FIELD: agricultural production, in particular, land fertility restoration. SUBSTANCE: method involves thinning soil to 0.5-1.2 m depth without soil layer turning by means of V-shaped blades; providing subsurface application of non-clarified animal sewage simultaneously with soil thinning; sowing ameliorant crops; cultivating crops following ameliorant crops in crop rotation on arable soil layer by differentially deepened cultivation process. Method allows soil fertility to be restored through the entire plowing depth for short time. EFFECT: increased efficiency in utilization of non-clarified animal sewage and full-value usage of ameliorant crop in planned crop rotations. 2 cl, 1 dwg
