Influence of Philazonit biopreparation on the fertility of the soil and yield of agricultural crops

Influence of biological destructors Phylazonit SV and soil inoculant Phylazonit TO on yield of agricultural crops and basic soil parameters were researched. They included the following bacterial strains Bacillus circulans, Pseudomonas putida, Azotobacter chroococcum, Bacillus megaterium. It was established, that using Phylazonit SV before plowing at the rate 10 l/ha and in spring Phylazonit TO at rate 15 l/ha have increased pea yield by 22.8%, soybean by 21.9%, potato by 11.2%, maize by 19.4%. Additionally, the hummus parameters increased by 0.03–0.08%, lightly hydrolyzed nitrogen by 1.0–7.0 mg/kg, phosphorous movable forms by 2.0–6.0 mg/kg, potassium’s movable forms by 3.0–13.0 mg/kg soil. The soil-centric technology besides Phylazonit SV and Phylazonit TO with mineral fertilizers input came to pea yield increase by 30.1%, soybean by 36.8%, potato by 22.9%, maize by 35.8%. The soil-centric technology came to humus parameters increase by 0.05–0.1%, lightly hydrolyzed nitrogen by 5.0–15.0 mg/kg, phosphorous mobile forms by 8.0–18.0 mg/kg and potassium movable forms by 6.0–18.0 mg/kg in soil. The researched technologies for soil fertility evaluation showed the following notional net income for pea growing 315,7– 522,2 UAH/ha, for soybean growing — 585,0– 764,4 UAH/ha, for potato growing — 4516,0– 6284,0 UAH/ha, for maize growing — 1324,0– 2014,0 UAH/ha. The usage of technology profitability made for pea 9.8–12.6%, for soybean 13.7–18.3%, for potato 56.1–111.8%, for maize 31.2–40.5%.
