FIELD: agriculture.
SUBSTANCE: in methods of subsurface-strip soil treatment, perfection is achieved based on using gradients by soil moisture and density, ensuring the capillary migration of water towards a less moist and more compacted strip. The funnel-shaped cross-section of the flat-strip soil treatment, taking into account the capacity of the non-capillary porosity and the slope of the subsoil permafrost "bottom" enhances the flow of gravitational water through the depressions into the subsoil layers of the soil, increasing the moisture conductivity of the surface-treated soil, saturating untreated strips with capillary moisture.
EFFECT: increased adaptability of autumn plowing, moisture charging, depth of soaking, reducting unproductive moisture loss and the soil deformation volume compared to deep subsurface tillage.
