The influence of soil protection technologies on the content of organic substance in leached chernozem

Abstract

he quantitative content of organic carbon and mobile organic matter, its share in the total organic carbon is estimated. A significant intraseasonal variation of organic carbon was revealed when using dump processing. For the first time, the long-term impact (9-10 years) of soil protection technologies on the dynamics of organic carbon content and its mobile forms was determined for the agricultural zone of the Krasnoyarsk territory. It is shown that the zero land treatment reduces the degree of mobility of organic matter, and the minimum treatment (disk plowing) causes a significant differentiation of the seed 0-5 cm and the underlying 5-20 cm layer according to the content of sorghum.
