Abstract

Taiga boreal forests growing in the Northern Hemisphere of our planet have an exceptional function of preserving the carbon balance on a global scale. However, active logging leads to the need for reforestation in these forests, including in areas with soil overwetting. The aim of the study is to model of the movement of the formation on the working surfaces of a forest plow used for the formation of linear microhill. For a theoretical study of the forest plow working process, a formalized mathematical description of the interaction of the plow working surfaces with the soil environment was performed. The research work with the model consisted in the implementation of simulation experiments to simulate the process of creating a linear microhill by a forest plow. According to the results of the research, the regularities of the influence of the contact of the plow bottom surface with the soil during its turnover on the amount of mass moved for lay-down in microhill per unit of time were obtained. Another series of simulation experiments made it possible to estimate the dependence of the crossing profile of microhill on soil moisture, taking into account the approach angle of the spherical disk.
