The article discusses the results of investigations carried out within the framework of the research project commissioned by the Ministry of Agriculture of the Russian Federation in 2020. In August 2019, a field experiment was laid for the disposal of straw of spring barley of Vladimir variety using a special machine for this, i.e. a unit for utilizing the non-grain part of the crop as a fertilizer. When disposing straw, it was processed with biopreparations-destructors: Agrinos-1 (2 l/ha), Sternifag SP (0.08 kg/ha), Biocomplex BTU (1 l/ha), humic product Ekorost (0.4 l/ha). The straw was crushed and embedded in the soil on the control plot without treatment with biological preparations. It was found that the process of straw decomposition is more intensive compared to that of 2018-2019 on average by 5 %. The variants with Agrinos 1 and Sternifag SP treatment showed better results and accelerated the degradation process by 20 % compared to the control. The biological productivity of spring oats of Skakun variety showed that all studied biological products had a positive effect on the increase in yield. The best indicators were achieved on the variants with Agrinos-1 and Sternifag SP equal to 48.9 dt/ha and 45.4 dt/ha, respectively (the control was 36.4 dt/ha).
