Abstract
Experimental field studies were carried out on the experimental field of Ulyanovsk State Agrarian University in 2018-2020. The experiment scheme in 2019 (laid in 2018) consisted of 4 variants: 1. Control (without fertilizers); 2. Zeolite in pure form, 500 kg / ha; 3. Organic mineral fertilizer, obtained by enriching zeolites with amino acids, 500 kg / ha; 4. Zeolite 500 kg / ha + N40 (carbamide at the dose of 40 kg of nitrogen per 1 ha). In 2020, the experiment was supplemented with four variants in order to identify more appropriate doses of fertilization (zeolite enriched with amino acids, 250 kg / ha; zeolite enriched with amino acids, 500 kg / ha; zeolite enriched with carbamide, 250 kg / ha; zeolite enriched with urea , 500 kg / ha). The experiments were carried out in 3-fold repetition with a randomized placement of plots. The effect of zeolite from Yushansk deposit of Ulyanovsk region and fertilizers based on it enriched with amino acids and urea were studied in the experiment, as well as their effect on general biological activity of leached black soil, on its agrochemical parameters, photosynthetic activity of soybean crops, yield and seed quality. A significant influence of experimental fertilizers on biological activity of the soil, improvement of nutrient regime, as well as the ability of zeolite to neutralize soil acidity was found. Improvement of the soil environment in case of application of zeolite enriched with amino acids and urea as a fertilizer contributed to an increase of soybean yields by 6-14% and by 12-31% to improvement of the product quality. With an increase of the dose of fertilizers, the yield of soybean seeds increased, but not proportionally.
