The aim of the study is to investigate the role of spring wheat and rapeseed straw using the biodestructor Mikotop in increasing the efficiency of mineral fertilizers in the cultivation of soybeans and spring wheat. The study was conducted under production conditions on the chernozem of the Biysk-Chumysh zone of the Altai Region of the Ivanov A.N. Peasant Farm. Two field experiments were laid out: the first – with the introduction of spring wheat straw, on which soybeans were grown, the background in this area was mineral fertilizers at a dose of N78P26K26, and the experiment options included the introduction of straw (0.85 and 1.9 t/ha), both separately and inoculated with the biopreparation Mikotop at a dose of 1 l/ha; The second was conducted with spring rapeseed straw, over which spring wheat was grown. The experimental design also included the N75P26K26, background. The experimental variants were similar, with straw doses of 1.8 and 2.5 t/ha, respectively. Yield, grain quality, and economic indicators were assessed. For this, plant samples were collected in five replicates using the sheaf method. Grain weight, protein, and gluten content were determined according to GOST standards, as well as farm-specific costs. When adding spring wheat straw alone, the soybean yield increased by 2.5–4.1 % with an increase in protein from 35.1 to 37.2–39.3 %. For the inoculated variants, it increased more significantly – by 7.5–12.3 % with a protein content of 36.5–39.6 %. In the experiment with rapeseed straw, the wheat yield increased in the inoculated variants by 6.7–7.8 % against 2.5–4.5 % with straw alone, protein by 2.4–2.7 %, and by 0.6 % with pure straw. The profitability level in the experiment with soybeans increased from 66.8 to 69.8–87.5 %, and with spring wheat – from 28.8 to 31.4–36.8 %. The results demonstrate the important role of the Mykotop decomposer in increasing crop yields and improving their quality, due to the absorption of nutrients from applied fertilizers.
