SU1391521A1 - Method of recultivation of land - Google Patents

Abstract

This invention relates to agriculture. The purpose of the invention is to increase the yield of agricultural crops due to fertility, improvement of water-physical and agrochemical properties of the formed soil profile. Mix potentially fertile rock 50-60 wt.% Loess, 35-40 wt.% Clay and 5-10 wt.% Sand. The mixture is placed in dumps with a layer of at least 2 m. A humified layer of soil with a thickness of 50 cm is applied to the formed surface. The yield of alfalfa (hay) grown on the formed soil was 85-90 centners / ha. 1 hp f-ly. i O)

The proposed method makes it possible to create a gy; a specially fertile layer with optimal hydrological and physical conditions, since as a result of mixing rocks with different physical-mechanical composition, uneven filtration of soil water is prevented due to the presence of thin and large-pore multilayer rocks in soil.

their profile, 1) even shrinkage.

As a result, the potential fertility of the binding rocks is increased, favorable conditions are created for the growth of agricultural crops for a long period.

Thus, the yield of alfalfa (hay) grown on the soil, the profile of which is formed by a cutting method, was 59-60 centners per hectare, and according to the proposed method, 85-90 centners per hectare.
