Features of snow retention and counteraction to wind erosion of soils due to high stubble residues formed by a reaper designed for two-phase harversting by batch method

Abstract

The article deals with issues related to the territorial and climatic features of agricultural activities in the Russian Federation. Due to the large area of the country, the conditions for agriculture in different regions may differ greatly. At the same time, a significant part of the territory is affected by soil erosion. The main types of erosion are considered. The essence of the process of wind erosion or deflation and its key features are analyzed. In addition to soil erosion, insufficient soil moisture was noted as a disadvantage in a number of regions. A number of solutions to these problems are considered. As a solution to the problem, it is proposed to use a Reaper for two-phase harvesting of grain crops, which is equipped with a device for forming strips of high stubble residues. Formed high stubble residues provide snow retention and allow to counteract soil erosion. The paper deals with General issues of technology and design of the proposed machine. The results of theoretical and experimental field research related to the issues under consideration are presented. © The Authors, published by EDP Sciences, 2020.
