Objective: The study of the influence of various agents of biologization and agricultural crops on fertility, biological and biochemical properties of light chestnut soils of 8-field and 3-field crop rotations
Material and methods: Methods were used that are generally accepted in ecology, biology, and soil science. We have determined the activity of soil oxidases, polyphenol oxidase, and peroxidase. In the present study, ANOVA and correlation analysis was carried out
Experimental: Crop rotation followed the following order: stem crops in winter and spring crops — weed-sensitive crops, and crops that depress weeds that enrich the soil with humus and nitrogen. The scientists have developed 8, 6, 5 and 3-field most effective biologized crop rotations.
Result and discussion: Cultivation of crops with maximum biologization of agriculture, which reduces the negative impact of production intensification factors on soil fertility and the possibility of wide introducing elements of the organic farming system in production. At a long-term organic farming hospital, where mineral fertilizers have not been used for more than 20 years, researchers annually receive more than 60 centers per hectare of winter wheat, 40 centers per hectare of soybean, 70 centers per hectare of corn and 400-450 centers per hectare of sugar beet root crops.
Conclusion: The research results proved that due to the rational composition and alternation of crops in biologized crop rotations, it is possible not only to prevent a decrease in humus in the soil, but also to increase the yield of field crops from rotation to rotation
