Several research papers emphasize that both species composition and land cover in Mediterranean ecosystems generally recover rapidly after fire. Mediterranean species have ecological strategies for the post-fire period, such as the ability to resprout, seed bank persistence, or the ability to grow or disperse. Here an abandoned agricultural field (AAF) near Biograd na moru (Croatia) was burned by an induced fire. Fifteen rings (diameter 0.2 m2 ) were established, five for each variant: I. unburned (UB), II. medium intensity (MB) and III. high intensity (HB), and observed within 12 months. The results showed that the functional group (FG) of grasses dominated in the variant MB, in contrast to the dominance of legumes in the variant HB. Compared to AAF, the number of forbs FG slightly decreased in both burn variants (MB, HB). The dominant strategy was competitors (C), followed by ruderal plants (R), whose numbers increased slightly after burning in the MB and HB variants, while stress tolerants decreased significantly in both variants. The total cover of renewed vegetation was higher on HB than on MB. These preliminary results indicate that the intensity of HB does not promote grass survival in the first year after fire, while legumes and forbs are more resistant to higher fire intensity and therefore have a higher chance of survival.

Soil sampling is the first step in generating field-specific information on which to base agricultural input decisions. The objective of the study was to evaluate spatial and temporal variability of soil pH, plant available phosphorus (P2O5) and potassium (K2O) content under variable mineral nitrogen (N) fertilization. The research was conducted on the experimental field within hydro-ameliorated cropland in the Western Pannonia subregion of Croatia (45°33’N, 16°31’E). Grid soil sampling (15x15 m ; n=200) was carried out with semi-automatic circular tractor soil probe at 30 cm depth after winter wheat harvest in 2010 and 2016 covering ten fertilization treatments (0-300 kg N ha-1). A sequence of spatial changes in soil properties was influenced by differences in N rates, liming, field drainage and specific terrain features, although similar spatial response was apparent for both investigated years. A two-way ANOVA revealed that only soil pH values significantly differed among two years (p

A neglected arable agricultural area near the town of Vrana near Lake Vrana was burned by an induced fire. The area is located in the transition zone between evergreen (Fraxino orni - Quercetum ilicis) and deciduous vegetation (Querco- Carpinetum orientalis). The agricultural site itself, immediately around the burned area of the experiment, is dominated by Mediterranean maquis with the characteristic species Pistacia lentiscus and the monoculture community of Foeniculum vulgare. The studied area is divided into three experimental variants (average slope 18%): I. (control - anthropogenic meadow), II. (lower intensity burning, burning 10 kg/m2 of straw) and III. ( higher intensity burning, burning 10 kg/m2 of straw and 15 kg of vine wood). Fifteen rings (diameter 0.2 m2) were established on the studied area, five on each variant. The growth and development of flora and vegetation were observed monthly. All inventoried plant species were identified, herbarized, digitised, and are available in the ZAGR online herbarium (http://herbarium.agr.hr/hr_search.html). Abundant growth of plant taxa from all three functional groups that follow different ecological survival strategies was observed on the control variant: legumes, forbs, and graminoids. The most abundant species included the very species that were recorded within the experimental rings, but also included several others that were not previously recorded in the burned experimental rings (Plantago lanceolata, Urospermum picroides, Sisymbrium officinale, Silene latifolia ssp. alba). On the variant with lower fire intensity, the dominance of monocotyledons from the Poaceae family is visible: Avena sativa, Dactylis glomerata, Hordeum murinum, Elymus repens and others. On the variant with higher fire intensity, the dominance of plants from the group and family of legumes (Fabaceae) was observed, for example, Vicia cracca, Vicia sativa and Lathyrus aphaca. Compared to the control variant, abundant plants from the forage functional group grew in both burn variants (higher and lower intensity): Foeniculum vulgare, Convolvulus arvensis, and C. cantabrica, which were also the first to emerge three weeks after the 2019 induced burn. Total cover of renewed vegetation did not exceed 25% at either fire intensity after 24 months. Based on this results, we conclude that higher fire intensity does not promote survival of therophyte (monocotyledonous) life form, while hemicryptophytes and hamephytes (dicotyledonous) are more resistant to higher fire intensity and therefore have a greater possibility of survival.

Nowadays, when the negative impact of nitrogen fertilization is recognized, requisites are arising to determine the actual contribution of specific agricultural practices on environment degradation. Isotope analyses are imposing as key techniques for confirmation of nitrogen origin in soil and agricultural impact on ecological footprint of nitrogen on environment. Main objectives of this research were: (a) to determine soil δ15N isotope content regarding the variable doses of nitrogen fertilization and soil depth ; (b) to determine δ15N isotopic signature in applied commercial nitrogen fertilizers. Research was based on 12 soil samples and 9 fertilizers [urea, granular and piled LAN (limestone ammonium nitrate) and six NPK fertilizer formulations]. Soil samples were collected from a stationary field experiment in 2018 located in central part of Croatia after 22 years of application variable nitrogen doses (0, 100, 200 and 300 kg N/ha) on three depths (0-30, 30-50 and 50-80 cm). Analyses were performed in 2021 in two replications and δ15N isotopes in soil and fertilizers were determined by the EA-IRMS method. The results reveal that variability of the δ15N isotope content in soil (+5.1 ‰ to +7.7 ‰) indicates the organic origin of nitrogen in the soil despite the long-term application of mineral nitrogen fertilizers. As a confirmation of this allegation the range of δ15N values in the applied nitrogen fertilizers was from -0.96 ‰ in piled LAN up to +3.26 ‰ in NPK 7-20-30, implying that observed fertilizers were produced by processes of "industrial" fixation of atmospheric nitrogen and they did not leave a mark on the total nitrogen in the soil.

Agriculture can contribute signifi cantly to climate change mitigation through biological carbon sequestration, i.e., the storage of atmospheric carbon in the plant pool through the process of photosynthesis. The objective of this study is to determine the carbon (C) and nitrogen (N) content in above- and below-ground biomass, as well as C and N balance of soybean biomass. Destructive harvest of aboveground (grain, stems, leaves, stubble) and belowground (root system) biomass of soybean (Glycine max L.) was conducted in Šašinovec, Croatia (45°50’ N ; 16°11’ E ; 120 m a.s.l.) in 2019. The C and N balance represents the diff erence between C and N gains (stems+leaves+stalks+root biomass) and losses (grain biomass) in the agroecosystem. The total dry matter yield is 16.53 t ha-1 and is composed of 23.7% grain, 48.6% stem, 20.8% leaf, 2.1% stubble and 4.9% root biomass. The average C and N content ranged from 25-55% and 0.5-7%, respectively. The total C balance is positive and is 3, 38 t ha-1, with total gains of 5, 52 t ha- 1 and total losses of 2, 14 t ha-1. The total N balance is negative and is -0.13 t ha-1, with total gains of 0.13 t ha-1 and total losses of 0.26 t ha-1. The negative N balance indicates that soybean biomass negatively aff ects soil quality and results in N losses from the agroecosystem, while the positive C balance indicates that soybean biomass can contribute to climate change mitigation through biological carbon sequestration under the studied agroecological conditions.

Nowadays, when soil pollution poses a worrisome threat to humanity, the need for soil protection is very pronounced with increasing requirements for methods that can quickly and accurately detect pollutants in the soil, especially metals. Portable X-ray fluorescence (pXRF) imposes itself as method with real-time and simultaneous multi- (total) element analysis, along with relatively low detection limits and relatively low cost. The goal of this research was to determine the concentrations of lead (Pb), nickel (Ni), chromium (Cr) and manganese (Mn) in referent soil samples by means of pXRF method and to determine the accuracy (RPD) and precision (RSD) of pXRF analyser using the referent soil samples. The research was based on analysis of 43 referent soil samples which were collected from 2009 to 2019 as part of participation of Analytical laboratory of Department of General Agronomy (Faculty of Agriculture, Zagreb) in Wageningen Evaluating Programme for Analytical Laboratories (WEPAL) within International Soil-analytical Exchange (ISE) program. Measurement was conducted by simple “point and shoot” technique on VantaTM handheld (portable) XRF analyser C Series (Olympus, USA, 2019). Results revealed that portable XRF analyser is capable of measuring Pb, Ni, Cr and Mn in ranges of concentrations (10.5 - 327 mg Pb/kg ; 18 - 70 mg Ni/kg ; 63 -255 mg Cr/kg ; 201 – 1435 mg Mn/kg) with excellent (RPD 0-10 %) to good (RPD 10-25 %) accuracy and acceptable precision (RSD < 20 % ; USA EPA, 2007) especially in clay soil samples. Also it is noticeable that poor accuracy (RPD > 50%) for investigated elements was determined in same soil samples with sandy texture.

Paleoclimate studies for long-term records are often obtained from speleothems fed with very slow drips that have a diffusional flow and consequently a limited amount of water available for monitoring studies. Using a HOBO U24-001 data logger, we have implemented a methodology for measuring electrical conductivity (EC) in drip water samples with volume

Long-term application of copper (Cu) based fungicides promotes Cu accumulation in agricultural soils. Copper is not biodegradable and can remain in the soil for decades and become a potential threat to the environment and human health. Therefore, the Cu levels in soil samples should be monitored frequently by rapid, selective, simple and low-cost analytical techniques. The aim of this study was to compare three soil analytical methods for determination of total Cu in soil. Soil samples were collected from agricultural land in Hrvatsko Zagorje (Rovno, near Krapina) where two vineyards are placed on the middle of the slope, and below them are arable land and meadow. At twelve positions of the investigated location 36 soil samples were collected from three different soil depths (0-10 cm, 10-20 cm and 20-30 cm). In air-dried, ground and homogenized soil samples, Cu content was detected by AAS, ICP-MS and pXRF methods. Before detection by AAS and ICP-MS, the soil samples were digested by aqua-regia. Determined Cu content varied in very similar ranges from 51.2 mg/kg to 444.3 mg/kg with average of 137.2 mg/kg for AAS ; from 48.6 mg/kg to 446.4 mg/kg and average of 138.0 mg/kg for ICP-MS and from 54.0 mg/kg to 435.3 mg/kg with average of 141.5 mg/kg for pXRF. The complete correlation was determined for detected Cu content between investigated methods and the correlation coefficients for the determined Cu content between individual methods were respectively: 0.9997 (AAS vs. ICP-MS), 0.9944 (AAS vs. pXRF) and 0.9940 (ICP- MS vs. pXRF).

Soil electrical conductivity (EC) is an important indicator of soil health. It affects crop yields and suitability, many soil properties like plant nutrient availability, and activity of soil microorganisms which influence key soil processes including the emission of greenhouse gases such as carbon dioxide i.e. soil respiration. While it is well known that major drivers of soil EC are soil temperature and moisture content, less is known on the relation between soil EC and respiration. Therefore, the objectives of this research were to determine relation of soil EC and soil microclimate (soil temperature and moisture), as well relation of soil EC and soil respiration under three different land covers. A study on soil EC, microclimate and respiration under bare soil, winter wheat and winter barley was carried out from November 2020 until July 2021 on experimental field near Osijek city, continental Croatia. The results showed that EC is more related to soil microclimate elements i.e. soil temperature and soil moisture content than on soil respiration. Between 17% and 47% of EC can be explained by soil microclimate elements and none i.e. only 4% to 12% by soil respiration.

The three greenhouse gases (GHGs) associated with agriculture include carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). While the CO2 represents the major GHG issue for the total economy, N2O, even though is a small part of the overall GHG issue, becomes the most important for agriculture considering soil management and fertilizer use. This research, conducted in a conventional agroecosystem under triticale vegetation in Popovaca, was based on measurement of CO2 and NO2 emissions using a static chambers for CO2 and method with passive samplers and static chambers for NO2. The aim of this study was to determine the amount of C-CO2 emitted from the soil into the atmosphere, depending on different amounts of nitrogen fertilizer (0-300 kg N/ha) during the vegetation. Also, the aim was to determine the suitability of the selected method for N-NO2 concentration measurement and to determine the potential impact of mineral fertilization on the N-NO2 emission (0 and 300 kg N/ha). Mean annual values of C-CO2 emissions ranged from 10.4 kg/ha×day on the treatment X (black fallow) up to 26.1 kg/ha×day on the control treatment (I) and treatment with 250 kg N/ha (VI). A weak correlation between the amount of nitrogen (0-300 kg/ha) and the emission of C-CO2 was determined (r = 0.26). The used method was suitable for N-NO2 concentration. Measured daily values of N-NO2 emission ranged from 1.66 to 7.18 mg/ha per day, depending on phenophase and treatment. Statistically significant differences in N-NO2 emission between two monitored treatments (300 kg N and 0 kg N) were not observed.

U slučaju pozitivnog otkrića, odnosno potvrde otkrića ugljikovodika nastaviti će se aktivnosti privođenja eksploataciji bušotine opremanjem i izgradnjom sabirno-transportnog sustava. Završetkom crpljenja ugljikovodika, poslije 20, 30 ili 40 godina temeljem ovih analiza utvrditi će se promjene koje su se desile kao posljedica višedesetljetnog crpljenja ugljikovodika. Na žalost u ovom slučaju nije se desila ta situacija. S obzirom na rezultate bušenja donijeta je odluka o rudarskoj likvidaciji bušotine i trajnom napuštanju kanala bušotine i bušotinskog radnog prostora. Kanal bušotine je likvidiran postavljanjem cementnih čepova po završetku izrade kanala bušotine, a nastavno na likvidaciju kanala bušotine uslijedila je sanacija bušotinskog radnog prostora i vraćanje u prvobitnu namjenu.

Anthropogenic climate change is altering ecological and human systems globally, including national parks that conserve unique but vulnerable ecosystems and biodiversity. Yet the magnitude and spatial patterns of climate change across national parks are generally unknown. The National Park (NP) Brijuni in Croatia encompasses 14 islands and islets covering an area of 33.9 km2 in the northern Adriatic Sea, representing a unique microenvironment with a specific biodiversity, natural, cultural and historical features. Due to its location, NP Brijuni is in direct threat of potentially strong air pollution from regional and long-range sources from continental Europe. However, the atmospheric pollution impacts to the area of the NP Brijuni have been unknown. This work presents the first insight into the air pollution sources, its seasonal variabilities as well as atmospheric deposition impacts to the area of NP Brijuni. The sampling campaign at NP Brijuni was conducted from June to November 2020 and included on-line measurements of black carbon (BC) concentrations and collection of particulate matter (PM10), wet and total deposition samples. The results of BC concentrations and its source apportionment and dataset comprising dominant ions (NO3-, SO42-, Cl-, Na+, K+, Ca2+, Mg2+, NH4+) and organic matter (organic carbon and water soluble organic carbon) in PM10 and deposition samples were statistically analysed and discussed considering different seasons, meteorological conditions and specific air-mass inputs in order to better understand the extent of the changing environment as a main prerequisites for air quality management, planning and implementation of appropriate environmental protection measures in the NP Brijuni.

Klimatske promjene jedan su od najvećih izazova s kojima se danas suočavamo. Sektor poljoprivrede predstavlja jedan od većih izvora emisija stakleničkih plinova kako u svijetu tako i u Hrvatskoj, a koje izravno utječu na sve veći problem klimatskih promjena. Jedan od glavnih čimbenika u borbi protiv njih je upravo tlo koje sadrži dva puta više ugljika u odnosu na atmosferu i stoga predstavlja važnu komponentu globalnog proračuna za ugljik. Ovisno o tome kako se njime gospodari, tlo može imati ulogu izvora ili skladišta C i N. Cilj ovog istraživanja bio je izmjeriti i prikazati količinu emitiranog C-CO2 iz poljoprivrednog tla te usporediti međusobnu ovisnost C-CO2 emisije o temperaturi i vlažnosti tla. Pokusno polje s 10 različitih gnojidbenih tretmana postavljeno je u središnjem dijelu Hrvatske, u Popovači, na dubokom distričnom pseudogleju u svrhu mjerenja emisija C-CO2 iz tla. Mjerenje koncentracije CO2 u tlu provedeno je metodom statičkih komora 8 puta tijekom vegetacijske godine u tri ponavljanja na svakom tretmanu. U neposrednoj blizini svake komore mjerili su se i parametri tla (temperatura, vlaga i elektrovodljivost). Prosječne godišnje vrijednosti C-CO2 kretale su se od 2, 7 kg ha-1×dan do 28, 9 kg ha-1×dan. Zabilježena je slaba pozitivna korelacija između prosječnih godišnjih vrijednosti C-CO2 i temperature tla, kao i između vrijednosti C-CO2 i vlage u tlu.

Zelenom gnojidbom tlo se obogaćuje organskom tvari, poboljšava se biološka aktivnost tla, koriste teže pristupačna hraniva, utječe na biološku drenažu tla, povećava kapacitet tla za vodu, utječe na pedohigijenu, osigurava opskrba tla organskom tvari i bolja pristupačnost hranjiva. Zelena gnojidba predstavlja važnu mjeru koja ima cilj očuvanje optimalnih fizikalnih svojstava i povećanje plodnosti tla. Ovim istraživanjem, potvrđeno je da zelena gnojidba povoljno utječe na reakciju tla, porast biogenih elemenata, kao i na poboljšanje njihovih odnosa u periodu od godine dana (jesen 2020. – jesen 2021.). Nije potvrđena korelacija između zelene gnojidbe i poboljšanja fizikalnih svojstava tla. Nije uočena pozitivna korelacija između zelene gnojidbe i prinosa kukuruza, obzirom da se prinos pokazao manjim na tretmanu na kojem je primijenjena zelena gnojidba. Potrebno je nastaviti istraživanja kako bi se potvrdili pozitivni rezultati, te kako bi se utvrdile promjene fizikalnih i kemijskih svojstava i uočio utjecaj zelene gnojidbe na iste, kao i na prinos uzgajanih usjeva.

One of the most significant questions of the world that struggles with how to address climate change is how to reduce increasing levels of carbon dioxide (CO2) in the atmosphere. One of the strategies for climate change mitigation is carbon sequestration i.e. storing of atmospheric carbon (C) into the plant/soil pool. This accomplishes not only the aim of reducing levels of atmospheric CO2 but it is also improving soil health, leading to higher yields, nutrient contents and other agroecological benefits. The relationship between carbon sequestration and plant/soil carbon input is complex and depends on many elements like land use types i.e. crop type and cultivar, soil properties, agrotechnical measures, etc. Therefore, the aim of this study is to determine the biomass yields and carbon sequestration potentials of two arable crops (winter wheat and winter barley) and their four different cultivars. In order to determine biomass yields, biomass carbon contents and sequestration potentials, four different cultivars of winter wheat (Srpanjka, Renata, El Nino, Kraljica) and winter barley (Rex, Lord, Barun, Panonac) were destructively harvested at three randomly chosen 1 m2 of each cultivar in continental part of Croatia at 2021 harvest. In this study, the above-ground (grain and straw: stems + leaves + chaff) and below-ground (roots + stubble) biomass yields, the allocation of atmospheric carbon within biomass and sequestration potentials od each cultivar will be presented.

Streljane i upotreba vatrenog oružja izvor su onečišćenja tla i okoliša, ali i rizika za zdravlje divljih životinja i ljudi. Krajem 2021. Europska agencija za kemikalije uputila je prijedlog EK za ograničenje upotrebe Pb na otvorenim prostorima upravo zbog dokazane toksičnosti na ekosustav. Kod disciplina streljaštva na leteće glinene golubove većinom se koristi streljivo s olovnom sačmom. Na streljani Luže u blizini Zagreba, a koja se koristi samo za olimpijske discipline Trap i Skeet, 2020. uzorkovano je tlo na dvije piste (C i D). Na prvoj streljačkoj pisti (C - koja se koristi od 1989.) godišnje se iskoristi oko 7 paleta meta, a na drugoj pisti (D - koja se koristi od 2006.) iskoristi se 5 paleta meta godišnje. Jedna paleta sadrži 8250 meta. Prosječno se po paleti iskoristi 11 000 komada streljiva, a svaki metak u prosjeku sadrži 24 g olovne sačme te 1, 3 g baruta. Iz toga proizlazi da na pisti C dolazi do transfera 1848 kg olova i 100, 1 kg baruta u okolni ekosustav, a na pisti D 1320 kg Pb i 71, 5 kg baruta godišnje. Cilj ovog rada bio je utvrditi sadržaj i prostornu varijabilnost koncentracije metala (Pb, Sb, Cu, Zn, Ni) u tlu na dvije piste streljane Luže, obzirom na utjecaj razdoblja korištenja piste i udaljenosti (-40 m, +5 m, +25 m, +50 m, +100 m, +240 m) od pozicije pucanja (0 m). Dugogodišnje korištenje streljane rezultiralo je da koncentracije nekih metala u tlu prelaze MDK (NN 71/19) za poljoprivredna tla (Pb, Sb, Ni i Zn na 100 m, te Pb na 50 m). Vrijednosti koncentracija Pb i Sb izmjerene na 100 m prelaze i intervencijsku vrijednost (Rijkswaterstaat Environment/2013) te zahtijevaju sanaciju. Utvrđena je i vrlo jaka korelacija između udaljenosti i kiselosti tla. Zabilježen je pad od čak 2, 14 pH jedinica na 100 m u odnosu na prirodno okolno tlo (-40 m i +240 m).

Radi održivosti uzgoja proteina u svijetu, sve se više potiče uzgoj insekata. U uzgoju nastaju nusproizvodi među kojima su ekskrementi insekata koji se nalaze na tržištu te predstavljaju tip poboljšivača tla. Njihova kvaliteta i efikasnost znanstveno su malo ispitani. Cilj rada bio je utvrditi kemijski sastav izmeta šturka (Gryllus assimilis Fab.) te efikasnost njegove primjene kao poboljšivača tla u poljskim uvjetima uzgoja salate (Lactuca sativa L.). Primjena izmeta šturka je pozitivno utjecala na tlo i kemijski sastav biljke ali nisu ustanovljeni statistički značajni rezultati u prinosima. Utvrđen NPK omjer šturkovog izmeta iznosio je 5:1:4.

Budući da se istražna bušotina Ždala-1 pokazala negativnom, pristupilo se prema projektu uklanjanja naftno-rudarskih objekata i postrojenja po kojem je bušotina likvidirana sukladno članku 185. Zakona o istraživanju i eksploataciji ugljikovodika (NN 52/18, 52/19), internom dokumentu „Postupku napuštanja rudarskih objekata, postrojenja, instalacija i uređaja u SD IPNP“ (US2_INA1_1, ver 03, od 08.04.2016.), Dopunskom rudarskom projektu remontnih radova na naftnom polju „Privlaka“ – tipski projekt (Klasa: UP/I- 310-01/98-03/96 ; Ur. broj: 526-04-99-06 od 26. 01. 1999.) u poglavlju 4.2.8. Tehnologija trajnog napuštanja bušotina te Glavnom tipskom rudarskom projektom „Sanacija isplačnih jama u INA- Naftaplinu“ (travanj 1990.). Građevinski i rudarski radovi izvedeni su u sukladnosti s pojednostavljenim rudarskim projektom. Ostali građevinski elementi koji su se nalazili na radnom prostoru bušotine su uklonjeni te zbrinuti na privremenu deponiju investitora kako bi se po potrebi ugradili na drugoj lokaciji. Da bi u cijelosti postupak sanacije bušotinskog radnog prostora bio priveden kraju potrebno je još narednih godina provesti mjere rekultivacije saniranog bušotinskog prostora kako je to navedeno u poglavlju 7 projekta rekultivacije u ovom elaboratu.
