In the development of resource-saving technologies of processing of sloping lands, which provides deep loosening, it was developed and patented a new method of processing initially resistant sloping lands, aimed at subsurface moisture accumulation on the slopes. A mathematical model of steady state, designed to study the issue of stability of surface soil moisture saturation. A new method of calculating the limit conditions for holding the treated soil moisture saturation on the slope. Define the tasks of the theoretical calculation of the balance of forces applied to the considered solids on an inclined surface. Analysis of the results revealed that the treated layer will be in a state of stable equilibrium.

The results of calculations on the stability of slope lands treated in a new way. Device intrasoil walls combined with loosened intervals allows prevent subsurface runoff water, which reduces surface erosion slopes, improves the fertility of farmland returns a highly eroded areas in turn, eliminates the wetlands at the foot of the slopes. Established that the stability of the treated soil layer on the slope ample.
