METHOD FOR RECLAMATION OF BLACK SOILS FERTILITY Russian patent published in 2016 - IPC A01B79/02 A01C21/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular, to agriculture and soil science. Method includes introduction of organic fertilizers, closing with disk harrows, sowing of green manure, ploughing and cultivation. Herewith before ploughing weeds together with it introduced is a mixed mass of manure with ground straw in the form of compost maintained within a site for 5-6 months at the ratio of manure to ground straw of 2:1 at the mixture humidity of 50-60 %. Prepared homogeneous mass is then uniformly scattered in the field and together with weeds is embedded into the soil by disk harrows in the third-fourth decade of May into the soil layer of 12-25 cm. Then deep ploughing down to 30 cm is performed, and liquid drains of the livestock sector are introduced in summer in dry weather. Formed on the ground surface crust is ripped with disk harrows. In autumn the mass is ploughed for spring sowing for the depth of 15-20 cm, and in the second spring cultivation or disking is performed, leveling and compaction with smooth water-filled rollers. Then the mixture of herbage is formed of naturally growing on black soils by sowing during May crops in the form of a mixture of seeds with a specified norm of sowing. Closing of green mass into the soil in autumn is used as an additional green manure of fertilizers, herewith plowing is carried out for spring sowing with transverse disking of the field. Phosphate-potassium fertilizers are introduced on the third year in spring at first, for example inter-row, processing of the sowed tilled crop. Fermentation products of multipurpose compost are added on the third year in spring.

EFFECT: method provides higher activity of soil microorganisms, reducing density of soil and erosion processes, increasing soil humus.
