Study of features of differentiated soil treatment by machine-tractor units on agricultural landscapes of slope lands

Abstract

Abstract The paper considers the features of anti-erosion contour tillage on slope lands, taking into account the location of technological furrows at an angle to the horizontal of the slope. Obtaining information about the terrain model is possible in different ways, including before processing and during the processing of the soil on the slope by a machine-tractor unit. In this case, it is necessary to calculate the angle of deviation of the soil treatment direction relative to the slope when pro-cessing the correct areas with such machines on a complex slope. It has been established that when technological furrows are placed in a straight line, the erosion process develops significantly, for example, when using passive working bodies of agricultural machines (tooth harrows, coverers) on slope lands. For processing complex slope lands, we propose to use the active harrow as an anti-erosion tool in a machine-tractor unit. We have obtained a mathematical model for processing complex slope lands with an active harrow as part of a machine-tractor unit. The proposed approach can be used on slope lands with a slope of up to 15 degrees. Thus, the prerequisites for contour processing of soil on slopes by forming technological furrows with a zero slope are justified, which excludes additional agrotechnical and hydrotechnical anti-erosion and reclamation measures on slope lands with a slope of up to 15 degrees.
