Abstract

Исследования проводили с целью оценки эффективности нового органоминерального удобрения отдельно и в сочетании с минеральными удобрениями. Работу выполняли в 2017-2019 гг. в условиях Ярославского региона на дерновоподзолистой глееватой среднесуглинистой почве. Схема опыта предусматривала следующие варианты: без удобрений; использованная минеральная вата Izovol Agro Universal; органо-минеральный субстрат; обеззараженный куриный помет; органо-минеральный субстрат + NPK; NPK. Исходное содержание органического вещества (ГОСТ26213-91) в почве пахотного слоя - 2,86 %, подвижных фосфора и калия (ГОСТ54650-2011) - 286,1 и 143 мг/ кг почвы соответственно, гидролитическая кислотность - 2,07 мг-экв./100 г почвы. Гидротермический коэффициент в годы исследований был равен 0,9...1,4. По результатам корреляционно-регрессионного анализа (при p<br />We evaluated the efficiency of a new organo-mineral fertilizer, applied separately and in combination with mineral fertilizers. The work was carried out in 2017-2019 under the conditions of the Yaroslavl region on sod-podzolic gleyic medium loamy soil. The design of the experiment included the following treatments: without fertilizers; used Izovol Agro Universal mineral wool; organo-mineral substrate (OMS); disinfected chicken manure; OMS + NPK; NPK. The initial content of organic matter (GOST26213-91) in the soil of the arable layer was 2.86%, the contents of mobile phosphorus and potassium (GOST 54650-2011) were 286.1 and 143 mg/kg of soil, respectively; the value of hydrolytic acidity was 2.07 mg-eq/100 g of soil. According to the results of the correlation-regression analysis, the overall productivity is closely related to the content of organic matter (r = 0.78), mobile forms of phosphorus (r = 0.78); somewhat weaker it is related to the content of mobile forms of potassium (r = 0.69), exchangeable acidity (r = 0.68) and S-value (r = 0.51). The best treatment in the experiment was the application of the OMS, consisting of prepared chicken manure and vegetation mats used in greenhouse production, in combination with the full rate of mineral fertilizers. It helped to improve the agrochemical state: the organic matter content increased by 0.20%, exchangeable acidity raised up to 5.64 units, the amount of absorbed bases grew by 0.85 mg-eq/100 g of soil, the contents of mobile phosphorus and potassium increased by 41.73 mg/kg and 19.45 mg/kg of soil, respectively. At the same time, the productivity of agricultural crops increased by49.04%. With this fertilizer system, high revenues from the sale of products (74,990.20 rubles/ha) and conditional net income per 1 ha (55,973.75 rubles/ha) were observed.
