The effect of zero-tillage technologies on the transformation of organic matter in leached chernozem

Abstract

Abstract The article considers the influence of resource-saving technologies in agricultural production during tillage. The possibilities of zero tillage in the conditions of agriculture ecologization are determined. The necessity of using soil protection technologies in connection with the use of tank mixture in the processing of the reference area is justified. The quantitative content of total organic carbon (Sorg), as well as alkaline-soluble and water-soluble organic matter, was estimated. Their share in the structure of Sorg is determined. For the first time in the agricultural zone of the Krasnoyarsk Region, the long-term effect (9-10 years) of zero technology on the dynamics of organic carbon content and its mobile forms was determined. Chemical and physico-chemical indicators relative to seasonality are presented. The degree of mobility of the organic matter of the soil treated by zero technology is determined and the reasons for this fact are revealed. It is shown that the zero technology reduces the degree of mobility of organic matter.
