METHOD FOR INCREASING FERTILITY AND PRODUCTIVITY OF SOILS OF AGRICULTURAL LANDS Russian patent published in 2023 - IPC A01C21/00 A01B79/02 

FIELD: agriculture; ecology.

SUBSTANCE: invention can be used for reclamation of agricultural land and increase of its fertility. The method includes sequential introduction of carbonate-containing raw materials into the soil, that is, dolomite flour, taking into account its hydrolytic acidity, and an organomineral complex, followed by their incorporation into the soil. As an organomineral complex, a mixture of effluent from methane generation of cattle manure, superphosphate and potassium chloride at a ratio of 100:3:1.5 with a moisture content of not more than 60% is used. The mixture is applied to the soil in a dose of 5-10 tons of dry matter per 1 ha with a frequency of once per 3-4 years.

EFFECT: method enables increasing the content of basic plant nutrients, increasing the content of environmentally friendly organic matter in the soil and improving its agrochemical properties and increasing crop yields.
