Abstract
While processing the soil with traditional plows at the same depth, a plow sole is formed in the subsurface layer, which leads to a deterioration in moisture absorption by the lower subsurface soil layer. As a result, water erosion occurs on the slopes. To overcome these limitations, the authors proposed an improved linear-step plow for soil slopes processing. Analytical expressions were obtained for determination the main parameters and traction resistance of the linearly-stepped broach-plow. It was indicated that the turnover of the layers with the lowest energy costs is provided with the following parameters of the plow of odd hulls: plow length is 75 cm, plow width is 25 cm, stabilizing plate height is 15 cm, and the minimum distance from the ploughshare toe to the stabilizing plate is 25 cm. An installation angle of the plate to the furrow bottom, the length of the plate and the width of the wing holders, as well as the physical and mechanical properties of the soil have a significant impact on the traction resistance of the hedge.
Highlights
It is known [1, 2, 3, 4] that a plow sole is formed with annual ploughing by standard plows at the same depth in the subsoil, the density of which exceeds by 2 or more the density of the arable layer
A large difference in densities leads to a deterioration of the moisture absorption by the lower subsurface soil layer
The subsurface drainage and water erosion occurs on the slopes
Summary
It is known [1, 2, 3, 4] that a plow sole is formed with annual ploughing by standard plows at the same depth in the subsoil, the density of which exceeds by 2 or more the density of the arable layer.
