Abstract
The main purpose of this study was to determine the biological activity of the soil by studying the intensity of decomposition of flax material in the studied experimental variants. It is precisely this use of inoculant, a selected valuable leguminous crop, that significantly increases the biological activity of the microorganisms present in it, characteristic of light chestnut soil. This application helps enrich the soil with peculiar bacteria that enhance nitrogen fixation from the atmosphere and turn it into accessible, easily digestible forms.
Materials and methods. Our observations were carried out from 2022 to 2023 on irrigated light chestnut soil at the experimental station “Irrigated” (Volgograd region, village Water). Two soil moisture regimes were considered, according to which the effectiveness of soybean seed treatment with a complex of bacterial nitrogen-fixing components was evaluated in comparison with the untreated version of the experiment (control).
Results. The obtained results of such observations convincingly prove that pre-sowing treatment of seed material with biological components has a positive effect on the biota ofthe studied soil profile. Data on the biological activity ofthe soil correlate with the yield and quality of the harvested grain, provided that the pre-irrigation moisture threshold is maintained at 80% of the lowest moisture capacity.
Conclusions. Constant moistening of the soil at the level of 80% HB when growing soybeans with pre-sowing inoculation of seeds makes it possible to obtain a grain harvest within two years of research atthe level of 2.85 t/ha with increased grain quality indicators, where the total nitrogen contentis 5.04%; phosphorus – 0.90%; potassium – 2.15%; crude fat – 21.21%, and fiber content is 9.74%.
