The Dynamics of consumption of items of food and crop yield of crop rotation depending on the processing systems of leached chernozem in the Central Black Earth region
The results of the study of the dynamics of biomass growth and consumption of nutrients by plants of crop rotation depending on soil treatment methods showed greater removal of nutrients by crops of clover and corn in the moldboard treatment, winter wheat, sugar beet and annual grasses - with a combined treatment of the soil. Modern varieties and hybrids consume more nutrients on the formation of 1 tonne of yield compared with the standard values. At subsurface tillage crop yields were reduced by 6-19%, energy efficiency by 10-13% compared to moldboard and combined treatments.
