The article describes the results of a study on the use of crop residues (straw) as a fertilizer in the organic farming system. The studies were carried out in two farms of Ryazan region and consisted in disposing of crop residues as a fertilizer using a special machine. It is a device for utilizing the non-grain part of the crop as a fertilizer and using the standard technology with the addition of biological products with the help of a sprayer. The design of the developed machine allows selection and grinding of the plant material with its simultaneous treatment with a working solution of biopreparations or stubble destructors. Recycled plant residues were treated with various biopreparations: Agrinos-1 1.2-2 l/ha, Sternifag SP 80 g/ha, Ecorost 0.4 l/ha and Biocomplex BTU 1 l/ha. As a control, the straw was crushed and embedded in the upper soil layers without treatment with biopreparations. From the moment of disposal of crop residues and until the beginning of spring barley sowing in April 2019, the activity of cellulose-degrading bacteria in the soil was recorded (using the linen method). Content of the main micro and macro elements was established by a comprehensive chemical analysis. Before harvesting in August 2019, biological productivity was recorded (it was 15.2% higher on variants using biopreparations for stubble destruction) and the quality was assessed by the protein content in the grain.
