The study aimed to evaluate the effectiveness of the use of biostimulants, such as humic acid preparation, Seaweed algae extract and microbial preparation BaikalEM, on plant growth and yield. The impact of biostimulants on plant development and crop yields was studied on sugar beet (Beta vulgaris) and maize (Zea mays). To achieve this goal, field studies were conducted to compare different biostimulants in terms of germination and yield (total crop weight, weight of a single fruit, sugar, starch and protein content). The study was conducted in April-August 2023 in the Sumy district of the Sumy region. Standard agronomic methods, including soil cultivation, measurement of plant growth and yield parameters, and statistical processing of the data were used in the study. The results showed that humic acids and algae extract, when applied separately, provided the highest seed germination and yield. Among all the variants of combined application, the most significant increase in germination rates for beetroot was provided by treatment with a combination of Seaweed and Baikal-EM – 91.7%. For maize, Seaweed with humic acids and Seaweed with Baikal-EM are 92% each. The combination of Seaweed and humic acids had the best effect on the yield of both crops: 460.9 c/ha for beetroot (compared to 325 c/ha without treatment) and 61 c/ha for corn (41.5 c/ha without treatment). The microbial preparation Baikal also demonstrated a positive effect, but its results were lower, and it proved effective in combination with humic acids. The results obtained indicate the feasibility of using humic acids and algae extract to increase plant productivity, while Baikal can be useful for improving the general condition of soil and plants in combination with other fertilisers.

In the late antique period (fourth-seventh centuries AD), lime was produced and consumed in great quantities for use in building, medicine, tanning, fulling, mortuary practices, and as an agricultural fertiliser. As a result, lime kilns (and associated slaking pits) are common features of late antique contexts – both in urban and rural environments and involving public institutions and private enterprise. In this paper we consider the archaeological remains of lime production and use in the eastern Mediterranean, a region in which dozens of lime production sites have been recorded. Focusing on the example of lime mortar production specifically, and following evidence for the associated chaîne opératoire, we demonstrate the versatility of the lime production process and how it frequently involved and even relied upon multiple industries.

Background: Climate change poses a significant threat to agricultural production worldwide, with developing countries being particularly vulnerable to its negative impacts. Agriculture, which is a crucial factor in ensuring food security and livelihoods, is particularly vulnerable to changes in climate patterns, such as increased temperatures, drought, and extreme weather events. One approach to addressing these challenges is by promoting the adoption of climate‐smart agriculture (CSA) practices among farmers. CSA combines traditional agricultural practices with innovative techniques and technologies to adapt to and mitigate the impacts of climate change. infrastructure. By adopting CSA practices, farmers can enhance their resilience to climate variability and improve their productivity. Objectives: This review examines the effectiveness of interventions promoting CSA to enhance farmers' knowledge of the benefits of CSA approaches, subsequent adoption of CSA, and disadoption of harmful agricultural practices in low‐ and middle‐income countries (LMICs). Search Methods: We searched 39 academic and online databases, websites, and repositories and screened over 19,000 experimental and quasi‐experimental publications to identify studies promoting CSA practices to women farmers. We conducted a citation tracking process on included studies and contacted experts to ensure a thorough search. Selection Criteria: The review focused on studies that included interventions promoting climate‐smart agricultural approaches. Using EPPI Reviewer 4, two review authors independently screened the impact evaluation using a standardized screening tool. Data Collection and Analysis: Information about participant characteristics, intervention characteristics, control conditions, research design, sample size, bias risk, outcomes, and results were gathered. Data collection and quantitative analysis were conducted using standard Campbell Collaboration methods. Main Results: Eight impact evaluations were found (two randomized controlled trials) evaluating the effects of CSA practices on farmer's knowledge gains of the benefits of CSA practices and subsequent adoption. Knowledge dissemination approaches such as Farmer Field Schools and weather and climate information services were found to positively impact farmers' knowledge and adoption of specific CSA practices. However, the evidence supporting this claim is uncertain as a high risk of bias was assessed for five of the eight included studies. However, we found no effects on the disadoption of harmful practices such as pesticide overuse. Authors' Conclusions: The evidence base for studies promoting climate‐smart agricultural approaches (CSA) to farmers in LMICs is small, and there is a lack of studies reporting sex‐disaggregated data and studies explicitly targeting women farmers. The review suggests that knowledge dissemination techniques are significantly effective in improving CSA knowledge and adoption, including integrated pest management techniques and their benefits, adoption of climate‐resilient rice seed varieties (STRVs), and use of botanical pesticides by farmers. More and better confidence studies are needed to inform policy and programming, including those that look at a wider range of interventions, including changing norms, values, and institutional arrangements.

In order to study the effects of combined application of compound fertilizer and branch fertilizer on the growth and yield of machine-transplanted rice, four hybrid rice varieties were used as experimental materials, and four fertilization treatments were set up by completely random design: compound fertilizer (T0), compound fertilizer + conventional branch fertilizer (T1), compound fertilizer + (branch fertilizer − 20%) (T2), compound fertilizer + (branch fertilizer + 20%) (T3). The results showed that the branch fertilizer could effectively promote the early growth and rapid development of tillers, and increase the agronomic traits such as chlorophyll content, LAI and dry matter accumulation. Among the four varieties, the yield of the V4 variety was the highest under T3 treatment, which was 11,471.15 kg·hm−2, which was 37.34% higher than that of the control, and the yield increase effect was the most significant. The correlations showed that dry matter accumulation and LAI were significantly or highly significantly positively correlated with the number of effective spikes and yield, and the number of effective spikes was highly significantly positively correlated with the yield. In general, the application of pitchfork fertiliser increased the effective number of spikes and the number of grains per spike of each variety to different degrees, which effectively promoted the improvement of the rice yield.

Various toxic and flammable gases exist in the fertilizer industry whose release quantification is very important regarding emergency preparedness, planning and response, and well-being of the community. ALOHA threat zones and threat at a point coupled with MARPLOT are evaluated for ammonia, methane, carbon dioxide and hydrogen release, and outdoor and indoor concentrations of these gases in nearby residences and highways calculated. These footprints are calculated using ALOHA which requires inputs such as site data, site location, building type, gas name, atmospheric inputs, release source information and dispersion model to display the threat zone, which can then be shown on MARPLOT. Potential impact of these releases on the community is mitigated through releasing equipment isolations, water sprays for dilutions, dilutions through steam or air and emergency sirens for information. This article covers hazards in the fertilizer industry, and provides general guidelines for operational staff of any industry to mitigate hazards. [ABSTRACT FROM AUTHOR]

Municipal organic solid waste in Palestine is causing several environmental and social problems. This paper studied management of this waste stream in the concept of urban mining and circular economy through composting and reuse the produced compost for different purposes as an indicator for the circular economy through the period extended from 2021 up to 2035. Two compost reuse scenarios are studied: use for agricultural purposes, and use as landfill cover materials. For agricultural purposes, compost can be used as an alternative fertilizer where nutrients in compost can replace the existing chemical fertilizers available in Palestine such as humic acid as a source of carbon, Ammonium Sulphate as a source of nitrogen, Triple Super Phosphate as a source of Phosphorus, and Potassium Phosphate source of Potassium. The estimated revenue from compost use in agriculture is USD 194.8 million in 2021 and USD 369.8 million in 2035. The estimated saving from using compost as landfill cover is USD 0.876 million annually, and USD 13.14 million during the 15 years' study period. Implementation of the circular economy principles in municipal solid waste management through composting can close the materials recycling loop, generating extra income, and adding net revenue to the national economy.

The distribution and overuse of chemical fertilizers in Iran are still a considerable issue, so further research is needed to gain a deeper understanding of the challenge. Accordingly, modifying farmers' inefficient behaviors toward the use of chemical fertilizers (UCFs) is a policy initiative taken by all countries to achieve sustainable agriculture, but the rate of adoption by stakeholders is a challenge, yet has the potential to be under study. Employing 375 potato farmers in Hamedan County, western Iran, the present research mainly investigated driving factors that account for and give new information about farmers' behavior toward the UCFs, Iran, where a substantial volume of agriculture products is produced in this district. The developed theory of planned behavior served as a predicting theoretical foundation to accomplish so. The resulting evidence made clear that 60 percent of the variance in farmers' behaviors of the UCFs is forecasted by the two constructs of farmers' intention and knowledge. This study concludes that farmers' behavior toward the UCFs is needed to be adjusted by providing farmers with the required knowledge and information. [ABSTRACT FROM AUTHOR]

The Brazilian savanna (Cerrado Biome) is one of the most important regions in the world in terms of food production, with the use of fertilizers based on nitrogen, phosphorus and potassium (NPK). When not applied properly, fertilizers can alter and affect water quality. The objective of this study was to evaluate the presence of these compounds in surface and groundwater in the Upper Jardim River Hydrographic Unit, Federal District, thus characterizing seasonal variations during the dry and rainy seasons in two periods. A total of 207 groundwater samples and 23 surface water samples were collected in the years 2014, 2015, 2019 and 2020. The parameters analyzed were pH and nitrate, nitrite, ammonium, phosphate and potassium ions. In groundwater samples, pH values were significantly higher and ion levels lower in samples collected during the early years (except for nitrate), and the ammonium concentrations were lower in the dry season than the rainy (in 2014 and 2019). In surface samples, total phosphorus levels were significantly higher in the rainy/2019 compared to the rainy/2020 season, while this tendency was inverted for potassium during the dry season. The use of NPK-based fertilizers has increased considerably in recent years in the region due to the expansion of the agricultural area, and although the results of the study show that concentrations in water are much lower than the maximum values allowed by Brazilian legislation, continuous monitoring is necessary to guarantee water quality.

From the vineyard to the bottle, the winemaking process generates a variety of by-products, such as vinasses, spent filter cakes, grape pomace, grape lees, and vine shoots. To avoid damaging the environment and to reduce economic impacts, the by-products and wastes must be handled, disposed of, or recycled properly. This review focuses on an environmentally friendly approach to the management and added value of winemaking by-products, such as grape pomace or grape marc, by using vermicomposting. Vermicompost is a well-known organic fertilizer with potential uses in soil bioremediation and the conservation of soil health. To achieve environmental neutral agriculture practices, vermicomposting is a promising tool for resilient and sustainable viticulture and winemaking. Vermicomposting is a simple, highly beneficial, and waste-free method of converting organic waste into compost with high agronomic value and a sustainable strategy in line with the principles of the circular economy.

In order to solve the problems of existing spiral fertilizer apparatuses, such as the variation in cavity filling rate with rotational speed, fluctuation of fertilizer discharge flow, and inability to discharge fertilizer precisely, a triple-head gradually reducing spiral fertilizer apparatus is designed, which gradually compresses fertilizer particles through the triple-head reducing fertilizer spiral structure to achieve complete cavity filling and uniform fertilizer discharge. The main factors that affect the particle motion state and the structural size of the spiral fertilizer through theoretical analysis are determined, and its theoretical fertilizer discharge amount and rotational speed are calculated. Using EDEM (Discrete Element Method Software 2022) to establish a simulation model of a single-head gradually reducing fertilizer apparatus, the spiral lead reduction percentage x1, spiral diameter reduction percentage x2, and rotational speed x3 are determined as experimental factors, and the filling rate μ and spiral torque Yaverage are used as experimental indicators to conduct a simulation study on the secondary universal rotation combination design experiment. The results show that when the rotational speed is 95 r/min, the spiral lead reduction percentage is 60.00~73.21%, the spiral diameter reduction percentage is 86.55~97.05%, the filling rate μ is greater than 95%, and the spiral torque Yaverage is less than 16 N·m. In order to further improve the uniformity of fertilizer discharge and ensure the controllable accuracy of fertilizer discharge, comparative verification experiments are conducted on single-, double-, and triple-head gradually reducing spiral fertilizer discharge devices and ordinary spiral fertilizer discharge devices. The results show that the precision of the gradually reducing spiral fertilizer apparatus is better than that of the ordinary spiral fertilizer apparatus. Moreover, it is determined that the three-head style performed best. The triple-head gradually reducing spiral fertilizer apparatus is also validated by randomly adjusting six rotational speeds. The experiment results show that the average deviation of the fertilizer discharge flow rate of the fertilizer apparatus from the preset value is 3.16%. The two have a minor deviation, and the fertilizer precision is high. Precise control of the amount of fertilizer discharged can be achieved by adjusting the rotational speed, and the research can provide a specific reference for the improved design and precise control of the spiral fertilizer apparatus.

The article investigates the effect of innovative forms of fertilizers containing a full set of macro and microelements on the condition of plants, yield and quality of sunflower seeds in the foothills of the Kabardino-Balkarian Republic. ORGANOMIX brand M for oilseeds has a fungicidal effect and, having an immunity inducer and growth stimulator in its composition, promotes plant growth and the formation of seed tissues, an increase in overall yield, the accumulation of fat in seeds, and an improvement in the quality indicators of sunflower seeds. The article presents average data for the period 2021-2023. Sunflower has high requirements for the provision of soil with nutrients and is especially sensitive to boron deficiency. Double non-root treatment of sunflower plants in the phase of 2-3 and 4-6 pairs of true leaves with liquid chelated fertilizer ORGANOMIX oilseed, enhanced with the microelement BOR, has made it possible to obtain the highest yield under the experimental conditions - 26.4 c / ha of sunflower seeds. The quality of sunflower seeds plays a major role for agricultural producers. The fat content of seeds is the main quality characteristic and it depends on the husk content, which is determined by hereditary characteristics and the external environment has little effect on it. In our experiment, the highest oil content was obtained in the variant of using the ORGANOMIX oil fertilizer, enhanced with microelements BOR and ZINC in a mixture with ORGANOSTIM - 47.0%, the husk content varied from 24.5 to 25.9%.

Relevance. The use of mineral fertilizers in the cultivation of tomato in the first place should ensure the best conditions for the nutrition of plants during the entire growing season in accordance with their need.The research methodology was based on generally accepted methods for vegetable growing. The main goal of this study was to improve the zonal technology for cultivating tomato in open ground using leaf dressing with KCL and KNO3 preparations, aimed at increasing the level of yield during irrigation in the north of the Astrakhan region. Field experiments were carried out at the experimental irrigated land use area of the Federal State Budgetary Scientific Institution "Caspian Agrarian Federal Scientific Center of the Russian Academy of Sciences" in the period from 2021 to 2023. The scientific novelty of the study was the theoretical and practical justification for the use of leaf dressing with KCL and KNO3 in the cultivation of vegetables, aimed at the formation of highly productive commercial products.Results. During the research work, a comparative analysis of various standards of use of drugs was carried out, highlighting the most promising option. Three-year studies found that the use of potassium fertilizer KCl with a concentration of 0.5%), 30... 40 days. after planting (flowering), 50 days. after planting and 60 days. after planting gave a significant increase in yield relative to the control option. Conclusions. Based on the results of the analysis, an average of five charges, the KCl treatment variant Background + 3 (concentration 0.5%) was identified, which had the highest yield of 130.56 t/ha. This option was significantly different from both control and other options under study. The increase relative to the control was + 4.08 t/ha or + 3.2%.

Relevance. The study of the reaction of potato varieties, especially new ones, to the use of a complex of agrotechnical techniques, including foliar top dressing with water-soluble fertilizers, is an urgent task. For this purpose, 4 potato varieties of different ripeness groups (Red Scarlett, Nevsky, Golubizna, Grand) were studied in two regions of Russia using agrochemicals Agrovin Micro. Methods. The article presents experimental data on the study of biometric indicators, yield and quality of potatoes for non-root top dressing in conditions of leached chernozem and sod-podzolic sandy loam soils of the Central region of Russia. The objects of research were potato varieties of various ripeness groups. Foliar fertilization of plants with agrochemicals Agrovin Micro was carried out in the phases of germination, budding and 20 days after the last treatment in two consumption rates – 1.0 and 2.0 l / ha. Control – without processing (K) with background N90Р90К135.Results. On average, over the years of research, the best options for all varieties turned out to be options with the use of additional leaf treatment with an agrochemical at a maximum dose of 2 liters /ha. Due to three-fold foliar top dressing for the critical phases of potato plant growth, the greatest yield increases and maximum values of dry matter and starch content to the mineral background were obtained. In the conditions of the Tambov region, the increase in yield, depending on the variety, ranged from 24.2 to 59.3% or 6.0-10.5 /ha and in the conditions of the Moscow region – 3.3-28.9% or 1.2-7.1 t/ha. The most suitable for processing into fried potato products from the studied varieties turned out to be Red Scarlett and Grand. All other things being equal, the color index of crispy potatoes and fries on these varieties was higher than the Nevsky variety by 1.0-1.5 points.

Organic fertilizers play a significant role in organic systems and sustainable soil management. In general, organic fertilizers increase soil fertilization and can reduce the negative effects of the excessive use of chemical fertilizers and synthetic man-made fertilizers. This study designed aimed to check the comparable effect between Organic and chemical fertilizer NPK on growth traits of Dedonia viscosa. the experiment conducted in Agriculture college forestry department in plastic house during October to April 2024. RCBD full factorial used to conduct the treatment, 10 replication per treatment with three fertilizers Organic humic acid, NPK chemical and control .in April the seedlings harvested, the biometric traits height and diameter measured in seedlings and biomass trait. The results show highly significancy about effect of plastic house conditions temperature and light on biometric growth of seedlings were p value ≤0.001 between D1 and D2 during the 6 months of experiment with increment 53 cm in height of seedling. And the results show significance between fertilizers effect on biometric and biomass growth traits (shoot biomass and root biomass) and seedling diameter if the p value were p value ≤0.05.so the data p value for the growth trait (Shoot biomass) for the seedlings showed significant P value ≤0.05 and ≤0.001 during the experiment duration between NPK and Humic acid and control. and the p value of anova table were ≥0.05 between NPK and Control and ≤0.001 between Control and humic acid. Cording to these results we recommend to propagate dedonia viscosa inside the plastic house to keep him from winter low temperature and wind outside and even we recommend to use organic humic acid fertilizer 10ml/ltr conc, even the NPK chemical can be used in 800 ppm conc and it give good results but less than humic acid which is get better growth traits biomet

The experience of technological development of our country is an important source of ideas and approaches to the further development of agriculture based on domestic equipment and technologies. The study of its evolution necessitates the using of periodization. It is currently undeveloped for chemization of agriculture, more often being replaced by a set of key dates and biographies. So, it is nesessary to develop a holistic version of the structuring of chemization history. (Research purpose) To propose and substantiate the authors’ version of Russian agriculture chemization periodization. (Materials and methods) Monographs, legal acts, collected works and publications of outstanding scientists were studied using chronological, genetic and periodization methods of historical research (Results and discussion) The proposed periodization integrates previous historical ideas and hypotheses. The chemization of Russian agriculture has more than 250 years of history, which can be divided into 6 stages: preparatory (prehistory of chemization, which has three sub-stages), formative, extensive, stabilization, intensive and decentralized. The starting point is a publication of work «On lands fertilization» by A.T. Bolotov in 1770. Currently, the prerequisites for a new stage in the development of chemization are being formed, and it main attributes are digitalization, mechanization and biologization in the highest degree. (Conclusions) The proposed approach to structuring the history of Russian agriculture chemization is useful both for researchers and for training organization. The presence of clear guidelines increases the effectiveness of studying the historical aspects of agriculture, science and technology, which are so necessary for the professional and personal development of future agronomists and engineers.

The carbon footprint of crop production on the lands of agricultural enterprises in Ukraine under crops of wheat, maize, sunflower seeds, rapeseed, soya beans, sugar beets, potatoes and vegetables was determined using the UN IPCC methodology. An increase in the carbon footprint of crop production in Ukraine during 1990–2021 was revealed, which is associated with a high level of nitrogen input from mineral fertilizers to the soil and mineralization of humus. In Ukraine, during 1990‒2021, a high level of humus mineralization was observed on the agricultural lands under crops of wheat, maize, sunflower seed, rapeseed, soya bean, sugar beet, potatoes, and vegetables ‒ 8‒1998 kg/ha/year with emitted into the air from 0.2 to 63.0 Tg of CO2/year. The average CO2 emissions from agricultural land per 1 Mg of main production of studied crops of Ukraine during 1990‒2021 are 46‒1109 kg and N2O emissions are 33‒452 kg CO2-eq., respectively. Among the studied crops, the highest emissions of CO2 per unit of production due to the mineralization of humus are for the cultivation of sunflower seeds ‒ 1109 kg/Mg/year, maize ‒ 868 and rapeseed ‒ 531 kg/Mg/year, and the lowest emissions for the cultivation of vegetables ‒ 46 kg/Mg/year (2021). The highest N2O emissions from agricultural land per unit of production for the cultivation of rapeseed ‒ 452 kg CO2-eq./Mg/year, sunflower seeds ‒ 368 and soya beans ‒ 300 kg CO2-eq./Mg/year, and the lowest emissions for the cultivation of vegetables and sugar beet ‒ 33 kg CO2-eq./Mg/year (2021). According to the prognosis, this tendency will lead not only to an increase in GHG emissions, but also to soil depletion and a decrease in the country's food security. By 2035 the average level of humus mineralization will be about 2200 kg/ha/year (R2 = 0.725), CO2 emissions per unit of the main production of crops will be about 800 kg of CO2 per 1 Mg of production per year (R2 = 0.657) and emissions of N2O from agricultural land per 1 Mg of main production of crops will be about 200 kg CO2-eq./year (R2 = 0.0591).

Under current conditions, ecological component is becoming increasingly important. Restoration of potential soil fertility by their saturation with organic matter of intermediate crop siderates is the basis for growing environmentally friendly and high-quality products. Development and adaptation of effective agricultural technologies for growing potatoes in order to obtain organic products is an important scientific area today. One of the tasks of our research was to identify the payback of organic farming elements at current prices, in particular material resources directed on obtaining maximum and quality of potato harvest in the process of its growing. The results of farming and economic efficiency of using intermediate cultivation crops on green manure while growing potato are given. As a result of the conducted research was revealed positive influence of intermediate crops of sideral crops on economic efficiency of potato growing. Application of post-harvest Raphanus sativum siderate provided the highest yield of potato tubers – 30.9 t ha-1 and starch yield – 4.08 t ha-1. In the case of post-harvest Raphanus sativum siderate when growing potato, the highest net profit was obtained – 1369 € ha–1 and an additional profit of 460 € ha–1. Application of post-harvest Raphanus sativum siderate provided the lowest cost of potato growing – 36.35 € t–1, and the highest profitability level of its cultivation – 121.7%, with a payback of additional costs – 0.43 € t–1.

ABSTRACTLand use/land cover (LULC) change, caused by human activities, can strongly affect wildlife species and their habitats. Yet, human impacts onto lakes and associated indicator bird species such as the lesser flamingos (Phoeniconaias minor) have rarely been investigated. We used remote sensing images from 1989 to 2019, with additional interviews and focus group discussions to investigate how LULC change and agricultural activities adjacent to the Momella lakes, Tanzania, have affected the flamingo habitat. Agricultural areas increased strongly over time, and most respondents earned their living through crop farming. The use of synthetic fertilizers, and limited knowledge about fertilizer effects on environmental health, were evident. We highlight that LULC data combined with socio-economic assessments is essential to understanding the dynamics and impacts of human activities on wildlife. We recommend training for sustainable farming practices around areas of high conservation values and integrating land use changes and socio-economic dynamics into conservation efforts.

This paper proposes a multi-site global optimisation model of blending operations, alternative routings and order scheduling with a co-production flow. It is performed in a phosphoric supply chain owning three open-pit mines of different geological structures and chemical compositions, each having a dry blending plant. One main challenge of the phosphate industries is to produce merchantable ores (MO) that verify a quality charter (chemical composition) with chemical heterogeneous source ores (SO). Thus, a process of SO blending followed by a treatment is mostly necessary to obtain the required MO. Six alternative routings exist to produce an MO; one of them involving a calcination plant generates a co-product. The model objective is to determine the least costly production programme of a set of MO orders to be delivered within precise time windows, in given quantities and compliance with a specific quality charter, by assigning for each MO its blending plant, routing, blend of SOs and production schedule; it also defines the feeding of the blending plants. A real case study illustrates the proposed model. [ABSTRACT FROM AUTHOR]

Purpose: to identify an effective combination of primary soil tillage methods, fertilizer background, water consumption features at different sowing dates and their influence on the yield of new pea varieties in Rostov region. Materials and methods. The research was carried out in 2022–2023 at the experimental stationary of the scientific center. The following were studied: basic soil tillage methods (plowing, combined, chiseling) (factor A); fertilizer backgrounds: 1) without fertilizers, 2) Р₄₀K₄₀, 3) P₆₀K₆₀, 4) P₈₀K₈₀, 5) N₁₅Р₄₀K₄₀, 6) N₃₀P₈₀K₈₀ (factor B). Sowing was carried out in two stages. Soils are ordinary chernozem. Results. Higher yields were obtained in the variants of the 1st sowing date, regardless of cultivation and fertilizers. The increase was 6.3–6.8 % for the Donets and 6.9–8.4 % for the Amulet varieties, compared with the data for the 2nd term. A decrease in yield was noted with combined and chisel tillage, regardless of the fertilizer background and sowing dates; it was 6.0–6.3 and 5.2–5.3 % for the Donets and Amulet varieties, respectively; 4.9–5.2 and 3.5–4.7 %, compared with plowing (factor A). The highest pea yield according to factor B was provided by the N₃₀P₈₀K₈₀ variant: 3.03 and 2.86 t/ha for the Donets varieties, 2.56 and 2.39 t/ha for the Amulet varieties. The yield increases reached 0.89–0.93 t/ha (44.3–45.2 %) and 0.67–0.71 t/ha (38.3–38.9 %), respectively, compared to the control. The difference in average yield between the P₈₀K₈₀ and N₃₀P₈₀K₈₀ variants did not exceed 0.09–0.13 t/ha for the Donets variety and 0.03–0.06 t/ha for the Amulet variety. Conclusions. The best average yield was obtained in the variant with plowing and N₃₀P₈₀K₈₀ nutrition at the first sowing period in 2023, amounting to 3.72 t/ha for the Donetsk variety and 2.91 t/ha for the Amulet variety. The lowest water consumption coefficient of peas was also noted here – 804 m³/t.

Basil (Ocimum basilicum L.) is a vital aromatic crop widely utilized in culinary and fragrance industries. The present study was conducted to implement a two-year field experiment (2019 and 2020) aimed to assess the impact of various fertilizers on the growth, yield, and essential oil composition of basil cultivated in Thanh Hoa Province, Vietnam. The fertilizer treatments included: no fertilizer (control), chemical fertilizer (NPK at 90-120-90 kg/ha), cow manure, chicken manure, and a combination of chemical fertilizer, cow manure, and chicken manure. The application of fertilizers resulted in significant improvements across various parameters compared to the control group. Basil plants treated with fertilizers exhibited increased height, la teral stem count, fresh and dry yields, chlorophyll and carotenoid content, essential oil yield, and essential oil content. The essential oil extracted from basil contained notable volatile compounds, with methyl chavicol, linalool, β-elemene, and epi-α-cadinol identified as the major constituents. The proportions of these compounds varied among the fertilizer treatments. Notably, the combined fertilization approach involving chemical fertilizers, cow manure, and chicken manure emerged as the most effective and significant in promoting basil growth and essential oil production. These findings not only contribute to the optimization of basil cultivation practices but also provide insights for the agricultural community, emphasizing the importance of balanced fertilization for maximizing the quality and yield of basil essential oil in the Vietnamese context.

There was studied the influence of soddy-podzolic light loamy soil of different cultivation status on the agronomic efficiency of mineral fertilizers application with varying doses of nitrogen and biological preparations applied against the mineral background, in Pskov region. On moderately cultivated soil the linear dependence of grain yield on nitrogen rates was established. An increase in nitrogen doses from 20 to 80 kg a. i./ha resulted in obtaining an additional yield compared to the control variant, which is dependent on soil pH: yield growth by 6% to 42% was recorded on soil with pH of 5.6; from 8% to 73% – on soil with pH of 5.3; from 32% to 69% – on soil with pH of 5.2; from 66% to 175% – on soil with pH of 4.8. Payback from applied fertilizers rose with increasing doses of nitrogen. Soil properties also influenced the payback value. The maximum payback, 12 kg of grain per 1 kg of NPK, was recorded when N80P40K70 with split nitrogen fertilizing was applied to the soil with pH = 4.8. The introduction of biological products to the variant with mineral fertilizers (N20P40K70 + N20) contributed to an increase in grain yield : the introduction of microbiological preparation Bisolbifitis provided additional 7.55%; spraying of foliar fertilizers – 3.67%–8.78%. On the soil with long-term cultivation status the dependence of yield on the doses of applied nitrogen in the range from 20 to 80 kg a. i./ha looked like a polynomial. Maximum yield was obtained in different years when nitrogen was applied at rates from 40 and 60 kg a. i./ha. An increase in the dose of nitrogen from 20 to 40 kg was accompanied in 2019 by an increase in the yield of grain from 11.2% to 22.6%. An increase in nitrogen rates from 20 to 60 kg in 2020 and 2021 resulted in the growth of grain yield from 20% to 65%. Respectively. When the most effective doses of nitrogen were applied the payback from fertilizers was 5 kg of grain per 1 kg of NPK in 2019; 7 kg of grain per 1 kg of NPK in 2020; and 10 kg of grain per 1 kg of NPK in 2021. On the soil cultivated and improved for a long-term the effect of foliar fertilizers with biological preparations Kodamine B-Mo and K-Humate-Na was less significant (3–3.5%).

Fertilizer application plays a crucial role in the decomposition of white poplar leaf litter and cycling of nutrients within forest ecosystems. The impact of various fertilizer additions on white poplar leaf litter and nutrient cycling is poorly understood. In this study, seven treatments were conducted at the following levels: Control (CK), no adding mineral fertilizers, N fertilization (+N), N and P fertilization (+NP), N, P, K fertilization (+NPK), P, K (+PK), manure fertilizer (+MF), and bird fertilizers (+BF) in a white poplar plantation in Qadis district, and used the litterbag techniques to measure litter mass remaining. The main objectives of our study were: (1) to explore the response of white poplar leaf litter decomposition to various fertilizers and accelerate the decomposition process; (2) to examine the relationship between C, N, and P concentration and their stoichiometric characteristic in leaf litter and soil. In this investigation, our results showed that white poplar leaf litter was significantly affected by fertilizers, and the decomposition process was greatly accelerated with + MF, +NPK, and + BF. The decay rate constant k (year −1) shows the decomposition rate of white poplar leaf litter as follows: +MF > +NPK > +BF > +PK > +NP > +N > CK (0.56, 0.53, 0.52, 0.51,0.51,0.5, and 0.46). Soil nutrients N, P and K increased significantly during the decomposition time with + MF, +NPK, and + BF, respectively, while C:N, C:P, and N:P ratios were highest in the white poplar leaf litter, and lowest in soil, we observed significant association between nutrients concentrations in soil and white poplar leaf and their stoichiometric. This current study concluded that adding + MF, +NPK and + BF fertilizers might be the preferred management option as they provided potentially beneficial changes in leaf litter decomposition and increased nutrient concentration. The data obtained will be a valuable reference for fertilization management strategies in forest ecosystems.

Abstract Sustainability in cotton production is inevitable because producing more cotton means more employment, economic acceleration, and industrial expansion. India, China, the United States, Brazil, and Pakistan contribute 74% of worldwide cotton production. Pakistan is contributing only 5%, despite the high potential of cotton. The average yield of cotton in Pakistan is stagnant at 570.99 kg hm−2, whereas it entails the highest cost of production among all other crops. The yield obtained in Pakistan is less than the potential, profitability is drastically lessening, and farmers are abandoning cotton for alternative kharif crops. Some traditional quantitative studies have unveiled different factors that affect cotton production. However, an in-depth qualitative study has never been conducted in Pakistan to explore the root causes of growing cotton crop failure. Following Moustakas’s traditional phenomenological guidelines, this phenomenological study was conducted in the district of Rahim Yar Khan in the core cotton zone of Punjab province. A total of 10 interviews were conducted with purposively selected cotton growers based on a criterion: (i) having more than 10 years of cotton growing experience, (ii) being a cotton grower, and (iii) having at least 10 years of formal schooling. Interviews were conducted face to face on an interview guide. One interview lasted 45–50 min, and responses were recorded and analyzed using a thematic analysis approach. A total of 6 themes emerged from the collected data, including (i) climate change, (ii) varietal problems, (iii) pesticide usage, (iv) sense of institutional services, (v) attitude of farmers and (vi) soil health and environment. These six merging themes contributed to cotton crop failure and yield decline. The deep exploration further summarized that researchers, extensionists, and farmers need to seriously consider variety, sowing time, and the environment to revive cotton crops. The detailed recommendations and policy guidelines are presented in this paper, highlighting the cotton sector’s research, development and investment areas.

This study examines the impact of internet usage on farmer's adoption behavior of fertilizer reduction and efficiency enhancement technologies in China. Based on 1,295 questionnaires in Henan Province, this study constructs a counterfactual analysis framework and used endogenous switching probit model to analyze the effects and pathways of internet usage on farmer's adoption behavior of chemical fertilizer reduction and efficiency enhancement technologies. The results indicate that. (1) The proportion of farmers adopting chemical fertilizer reduction and efficiency enhancement technologies is 60.15%, while the proportion of farmers not adopting these technologies is 39.85%. (2) Internet usage directly influences farmers' adoption of fertilizer reduction and efficiency enhancement technologies. According to counterfactual assumption analysis, if farmers who currently use the Internet were to stop using it, the probability of them adopting these technologies would decrease by 28.09%. Conversely, for farmers who do not currently use the Internet, if they were to start using it, the probability of them adopting fertilizer reduction and efficiency enhancement technologies would increase by 40.67%. (3) Internet usage indirectly influences farmers' adoption behavior through mediating pathways of expected benefits and risk perception. In addition, social networks negatively moderate the impact of internet usage on farmers' behavior of chemical fertilizer reduction and efficiency enhancement technologies. [ABSTRACT FROM AUTHOR]

Timely and accurate acquisition of cotton seedling information is crucial for seedling replenishment, yield increase, and effective cotton field management. This study proposes a cotton seedling recognition model and weed removal method for high-resolution UAV (Unmanned Aerial Vehicle) remote sensing images. First, the image information of cotton seedlings is enhanced by calculating the remote sensing index and using threshold segmentation. Second, the recognition model is constructed based on the spatial morphological characteristics of cotton seedlings, with weed interference removed using the straight-line method. Finally, the growth condition of cotton seedlings in farmland is comprehensively evaluated by calculating the seedling emergence rate and coverage rate. The experimental results show that: (1) the combination of the GLI (Green Leaf Index) and Otsu threshold segmentation algorithm effectively distinguishes cotton seedlings from the soil background and accurately portrays cotton seedling contours, further enhancing image information; (2) the proposed recognition model achieves an average overall accuracy of 95.75%, making it a practical method for cotton seedling recognition; and (3) the overall growth condition of cotton seedlings in the study area is good, enabling farmers to apply appropriate seedling replenishment and fertilizer based on the comprehensive cotton evaluation map to further improve the final cotton yield. This study aims to provide new research ideas for crop seedling identification and serve as a reference for the practical application of UAVs in crop monitoring. [ABSTRACT FROM AUTHOR]

Zinc (Zn) is the most commonly found deficient micronutient in agricultural soils worldwide, limiting crop yield and reducing food quality. Zinc‐enriched fertilizers have been successfully used to tackle crop Zn deficiency. However, Zn solubility is reduced after addition to phosphate fertilizers due to the formation of sparingly soluble precipitates, decreasing Zn availability to crops. We hypothesized that the availability of Zn in the fertilizer to plants is related to its speciation in the fertilizer. We evaluated a range of ammonium phosphate fertilizers using X‐ray absorption near‐edge structure and assessed the water‐solubility of Zn in the formulations. Four Zn species were identified in these fertilizers, with zinc ammonium phosphate the most abundant one. The speciation of Zn in the fertilizer had little relationship with the water solubility of Zn in the final product. Zinc solubility was driven by fertilizer pH, with lower pH resulting in higher solubility. We concluded that added Zn reacts with the fertilizer matrix to form mainly zinc (ammonium) phosphates, and when the fertilizer is dissolved in water, hopeite controls the solubility. Based on these findings, we tested whether a barrier coating between the P granule and the Zn compound could prevent reaction between Zn and P and thus enhance Zn availability. Indeed, higher Zn uptake was observed in an isotopically labeled fertilizer growth trial when a barrier coating physically separated Zn and P in the fertilizer. In summary, Zn availability to crops can be maximized by decreasing fertilizer pH and separating P and Zn in the granule. [ABSTRACT FROM AUTHOR]

Gaining a comprehensive understanding of the carbon emissions cycle in the atmosphere resulting from agricultural activities is crucial for assessing its influence on environmental quality. This study used panel datasets covering the period from 1990-2022 to investigate the influence of wheat and rice production on environmental quality in the six mega agricultural provinces of China namely Anhui, Hebei, Hubei, Henan, Jiangsu, and Sichuan. Study employed several econometric approaches such as Cross-Sectional Dependency tests, unit root and cointegration tests, Panel Mean Group Autoregressive Distributed Lag (PMG-ARDL), Panel Quantile (PQ) and Panel Least Square (PLS) regression analysis for the robustness of the findings. The empirical findings of PMG-ARDL model reveal that rice production positively increases CO2 emissions in the long run. The variables fertilizers usage, agricultural water consumption and agricultural credit also have positive impact on CO2 emission in the long run. Further, short-term results reveal that all the concerned variables positively contribute to increase the CO2 emissions. The PQR results illustrate that rice and wheat production, fertilizer consumption, agricultural water usage, agricultural credit and agricultural GDP have positive and significant impact on CO2 emission across the quantiles. Additionally, PLS outcomes show positive and significant association between wheat productivity, agricultural credit, fertilizer and agricultural GDP on CO2 emissions. The Dumitrescu and Hurlin (D-H) panel causality show unidirectional association among: carbon emission → pesticides use, carbon emission → temperature, and carbon emission → agricultural GDP. A significant bidirectional causal association was found between: carbon emission ↔ rice production, carbon emission ↔ wheat production, carbon emission ↔ fertilizers use, carbon emission ↔ agricultural water use, and carbon emission ↔ agricultural credit. These findings contribute to the understanding of the drivers of CO2 emissions in agriculture and provide valuable insights for policymakers aiming to mitigate environmental impacts while promoting sustainable agriculture, resilience, financial support to encourage green technology and implement robust monitoring mechanisms to protect quality of environment and agricultural sustainability.

Worldwide organic amendments have received much attention to improve soil fertility and crop productivity. Partial substitution of inorganic fertilizer through organic manure is a promising approach to decrease chemical fertilizer input while stabilizing or increasing crop yield. Field experiments were conducted in Hubei and Hunan provinces to assess the impact of partial substitution of chemical fertilizer through organic manure on cotton yield and soil properties during 2016 and 2017. The experimental plots (50 m2) were arranged in a randomized block design, with six treatments, and three replicates for each treatment. Our results revealed that the yield of 100% chemical fertilizer treatments was significantly higher than no fertilizer treatment in 2016, and the yield of organic fertilizer substitution treatments was higher than 100% chemical fertilizer and no fertilizer in 2017 in Hubei province. In Hunan province, the yield of replacing part of chemical fertilizer with organic fertilizer and 100% chemical fertilizer treatment was higher than those of 100% organic fertilizer and no fertilizer treatment over 2 years. Application of 100% organic fertilizer was found to be more beneficial in terms of improving soil fertility in Hubei provinces during both years. The substitution of chemical fertilizer by 50% organic fertilizer was effective to improve soil fertility and exerted a significant effect on soil available phosphorus, potassium in Hunan provinces during both years. Collectively, these results indicate that replace 100% chemical fertilizer through organic fertilizer in Hubei province and substitution of 50% chemical fertilizer in Hunan province could increase the cotton yield, improve soil fertility and reduce inorganic fertilizers, which have a potential impact on sustainable production of cotton.

In the present study grafted sericin/sodium alginate based encapsulated sustained release NPK fertilizer has been developed. Grafting of sericin/sodium alginate with acrylic acid-co-acrylamide has been performed by using microwave based grafting technique. The ratio of sodium alginate and sericin has been optimized for optimal release of NPK fertilizer, and it was found 0.7:0.3 ratio gives optimum release of encapsulated NPK fertilizer. The developed beads were characterized by studying bead size, encapsulation efficiency, swelling characteristics and cumulative release characteristics. The beads were found to have size range between 0.83 and 1.46 mm. The swelling kinetics of the beads in neutral, acidic and basic medium was found to obey pseudo second order kinetic model with value more than 0.98. The synthesized beads was found to obey Korsmeyer–Peppas release kinetic model. [ABSTRACT FROM AUTHOR]

This contribution examines the development of the European Union's nutrient policy from 2000 to 2022. It focuses on the policy's shift orienting toward expert knowledge and technological innovations in nutrient recovery and recycling, and explores the resulting (de)politicization of the policy area. Drawing on evolutionary policy change, agri-food (de)politicization, and agrifood technology innovation research, a three-phase development is identified through qualitative document and public feedback data analysis. The policy development started with a focus on environmental issues and nutrient scarcity in the 2000s (phase 1), expanded to nutrient recycling as a means to close the nutrient-food loop in the mid-2010s (phase 2), and began utilizing secondary nutrient sources for agri-food production and to ensure a stable supply of fertilizers in the 2020s (phase 3). The study shows that while expert knowledge and technological advancements have steered sectoral policies toward a circular agri-food system, they have also led to the EU's nutrient policy adopting a technocratic approach, privileging specific expert insights and depoliticizing the policy area. The findings highlight the intricate relationship between technological innovation, policy evolution, and public engagement in shaping the European agri-food system. [ABSTRACT FROM AUTHOR]

AbstractThe study aims to determine the nutrient chemical forms, storage effects, and phytotoxicity of fertilizers made from nutrient-rich materials and municipal organic waste in order to control the impact of farming practices on the ecology. Laboratory-scale experiments were conducted at 3-month intervals over a period of 15 months to determine the binding forms of phosphate and nitrogen, and other quality parameters of fertilizers. The germination index (GI) method was used to assess the phytotoxicity of the fertilizers at three different rates of applications- 2.0, 2.5, and 3.0 tonnes ha−1 on maize (Zea mays L.) and soybean (Glycine max). It was found that animal-based and organic mixture fertilizers had the highest levels of ammoniacal nitrogen and nitrate: NH4+-N (0.3 ± 0.0%) and NO3-N (0.7 ± 0.0%), respectively. Rock-based fertilizer had the highest levels of water-soluble (7.0 ± 0.0%) and neutral ammonium citrate soluble (4.1 ± 0.0%) forms of nitrogen and potassium, which are readily available to crops. The GI values of the fertilizers were generally above the safety standard of ≥80, except for synthetic fertilizer when applied on soybeans at 3.0 tonnes ha−1 (74.2). While organic fertilizers were deemed safe for application on the test crops, it is advised to avoid storing the fertilizers for an extended period of time due to potential chemical and biological changes that might affect the biome.

The ‘Okitsu No. 58’ citrus variety is highly prone to fruit cracking, which jeopardizes yield and results in economic losses. In this study, we investigated the impacts of spraying 5 distinct concentrations (0.1, 0.2, 0.3, 0.4, and 0.5 g/L) of chelated calcium (Ca) or silicon (Si) fertilizers at the young fruit stage (60-90 days after flowering, DAF) on fruit cracking and quality in the citrus variety ‘Okitsu No. 58’. The results showed either Ca or Si fertilizer treatments reduced fruit cracking. We found that all Ca and partial Si treatments (0.4 and 0.5 g/L) significantly promoted the accumulation of Ca content in the peel. Notably, Ca or Si treatments significantly reduced polygalacturonase (PG) activity and inhibited the production of water-soluble pectin (WSP) in the peel. Additionally, Ca or Si treatments elevated the superoxide dismutase (SOD) activity and decreased the malondialdehyde (MDA) content of the peels. Changes in these parameters likely contributed to strengthening the durability of peel cell wall constituents, thus enhancing the fruit’s resistance to fruit cracking. Overall, except for the C3 (0.3 g/L of Ca), Ca or Si fertilizers contributed to fruit conventional quality, mainly in terms of higher soluble sugars (SS) and SS/TA (titratable acid). Therefore, our findings will provide a reference for the prevention and control of citrus fruit cracking and the development of new fertilizers. [ABSTRACT FROM AUTHOR]

The latest study aimed to analyze the path coefficient for synthetic cultivars of maize (Zea mays L.) to determine the selection criterion for improved grain yield. In achieving this goal, a field experiment commenced in 2022 at the Ibn-Al-Bitar Preparatory Vocational School, Kerbala Governorate, Iraq. The study set up in a randomized complete block design (RCBD) used a split-plot arrangement and three replications. The main plots comprised six combinations of mineral and organic fertilizers, while subplots were the six synthetic corn cultivars, Fajr1, Maha, 5018, Sumer, Sarah, and Baghdad-3. The genotypic path coefficient analysis showed that grains per ear in the first and second fertilizer levels could benefit as a selection index, achieving the highest total effect (genotypic correlation) of 0.9459 and 0.9957, respectively, obtained through an indirect influence of the biological yield. The third level of fertilizer combination gave a harvest index that can also be a selection index because it showed the highest total result of 0.9825, obtained from a direct consequence of the grain yield (0.8745). In the fourth fertilizer combination, the biological yield can become a selection index because it gained the highest total outcome of 0.9898 from the direct effect of the grain yield (6.7848). In the fifth and sixth fertilizer combinations, the total uptake of nitrogen may be the basis for the selection index reaching the maximum total effects of 0.9806 and 0.9834, respectively, acquired through indirect effects of the biological yield in the fifth and total uptake of phosphorus in the sixth fertilizer combination.

Long-term use of inorganic fertilizers has negatively influenced rice productivity, being unsafe environmentally. The planned strategy sought to improve rice (Oryza sativa L.) production with a quality of environment-friendly rice cultivation by reducing the excessive inorganic fertilizers. The latest research aimed to analyze the effects of liquid organic fertilizer and urea on the growth and productivity of lowland rice managed with irregular irrigation. The urea (U) comprised four doses, i.e., control 0 kg/ha (U0), 50, 100, and 150 kg/ha (U1-U3, respectively), which fertilized the main plots. The liquid organic fertilizer (LOF) (P) also comprised four levels, viz., control 0 cc/L (P0), 2, 4, and 6 cc/L of water (P1-P3, respectively), which treated the subplots. The urea (100 kg/ha) application resulted in the highest average number of productive tillers (16.8) and the topmost percentage of full grain (84.47%). However, the urea fertilizer (150 kg/ha) produced the maximum flag leaf length (32.3 cm). The LOF concentration (4 cc/L) produced the superior 100-grain weight (2.84 g). The LOF (6 cc/L) produced the utmost index of chlorophyll a (236.43 μmol/m2), chlorophyll b (95.83 μmol.m-2), and total chlorophyll (339.64 μmol.m-2). The results showed that the combination of urea fertilizer (150 and 100 kg/ha) and liquid organic fertilizer concentration (LOF 6 cc/L) provided the best productivity of 6.26 and 6.13 t/ha, respectively.

Continuous addition of inorganic fertilizer and farm yard manure (FYM) alone or in combination is necessary to assess the changes in yield and soil properties. Therefore, a study was conducted for consecutive two years on nutrient management with nine treatments viz. T1- control, T2-100% FYM (N equivalent basis), T3-100% N, T4-NP, T5-NK, T6-PK, T7-NPK, T8-100% NPK+ FYM (recommended Practice) and T9- 150% NPK+ FYM to assess the influence of different treatments on yield, sustainable yield index, soil physic-chemical properties and soil carbon stock and sequestration rate in cauliflower and capsicum cropping sequence. Results showed that the addition of farm yard manure alone or in a combination with chemical fertilizers contributed to higher soil organic stock and soil carbon sequestration rate. Application of 150% NPK + FYM improved the SYI of system by 49.4% over a control. This treatment increases soil carbon stock by 12.5% from 25.9 Mg ha−1 to 29.6 Mg ha−1 and recorded with maximum soil carbon sequestration rate, i.e. 2.21 Mg C m−3 year−1 over the 2 years. Thus, balanced fertilization of NPK and FYM is beneficial for the maintenance of soil physical health, improving CEC and macro and micronutrient levels. [ABSTRACT FROM AUTHOR]
