Nitrogen state of Haplic Chernozem of the European part of Southern Russia in the implementation of resource-saving technologies.

Background: The prolonged use of traditional moldboard ploughing often results in soil degradation and, ultimately, has an impact on national food security. Therefore, the implementation of resource-saving technologies (minimal and No-till) is a promising approach in the development of agriculture, especially in drought regions. The present study reports the results of long-term research on the effect of various tillage methods (moldboard ploughing, minimal tillage and No-till technique) on the nitrogen content of Haplic Chernozem of the European part of Southern Russia.
