The influence of the systems of basic tillage and biological products on the agrochemical properties of the soil and productivity of field crops

Abstract

Abstract The agrochemical properties of the soil make it possible to assess the level of its fertility. The search for new forage crops is an urgent task in agriculture. Under the conditions of a high anthropogenic impact of man on soils through the introduction of mineral fertilizers and pesticides, the use of biological products in the cultivation of field crops is a solution to most environmental problems in the soil. This article presents materials on the study of the influence of various systems of basic soil cultivation and biological products on the agrochemical properties of the soil, as well as the productivity of field crops. The content of organic matter, the content of mobile phosphorus, the content of exchangeable potassium, hydrolytic and exchangeable acidity, and the amount of absorbed bases were determined. The yield of green mass and the yield of feed units of new promising crops for the soil and climatic conditions of the Yaroslavl region - soybeans, amaranth and buckwheat - were assessed. The studies were carried out under the conditions of a field stationary three-factor experiment on sod-podzolic medium loamy gley soil of the experimental field of the Yaroslavl State Agricultural Academy. The positive role of using Baikal EM-1 in the system of moldboard processing in buckwheat crops is shown. In this case, there is an improvement in most agrochemical indicators of fertility and it is possible to obtain maximum productivity.
