Abstract

Studies have shown a high efficacy of the drug used to fertilize chernozem soils for potatoes, the yield increase was 2.8 t / ha or 34.6% compared to the control. The use of this fertilizer in a dose of 100 kg / ha on the background of phosphorus gave an increase of 2.3 times higher than the control. The results of laboratory studies have shown a favorable effect of the drug on the nutritional regime of ordinary chernozem: the supply of soil with easily hydrolysable nitrogen, during the growing season, on options 100 - 500 kg / ha, increased from very low - 19.06 mg / kg to an average of 40 mg / kg, depending on from doses of introduction; The availability of mobile phosphorus on the drug options 100-500 kg / ha (against the background of phosphorus) increased from a
very low 10 mg / kg to an average of 45.21 mg / kg. The drug contributed to the increase of microbiological activity and neutralization of the soil environment. an increase in the yield of potatoes in 2017 was noted on all fertilized variants, the most effective were doses of 100 and 400 kg / ha, where the yield increase was 144.6% and 147.1%. In 2018, a high correlation was
noted between the doses of fertilizer applied and the yield of potatoes. A substantial increase in yield was given by doses of the drug 300-500 kg / ha (30.8% - 34.6%).
