Assessment of the impact of crop cultivation on the reproduction of land resources

Abstract

The paper assesses the impact of crop cultivation on the reproduction of land resources. It is determined that the change in the yield of major agricultural crops shows an upward trend. It was determined that crop yields are volatile due to natural and climatic phenomena. By comparing the values of nutrient removal with yield, it is determined that the most resource-intensive crop is corn, and the least - rapeseed. By comparing the removal and application of nutrients for the main agricultural crops, the conclusion is made about the narrow character of reproduction of land resources in Russia. It was found that for all crops, with the exception of rapeseed, there is a situation in which the removal of nutrients exceeds the volume of their application. The general conclusion of the study is the revealed trend of soil fertility reduction and degradation of land resources of the agricultural sector.
