COMPOSITION OF STRUCTURE-FORMING MATERIALS Russian patent published in 2014 - IPC C09K17/14 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture and specifically to soil reclamation, particularly compositions and methods for controlling water erosion of soil. The structure-forming materials used are dirt pile rocks, bentonite clay, expanded clay screenings and shell limestone. The composition of structure-forming materials includes: expanded clay screenings of particle size 0.315-1 mm 5%, dirt pile rocks of particle size 15-20 mm 10%, shell limestone of particle size 5-10 mm 55%, bentonite clay of particle size 1-10 mm 30%. The composition of structure-forming materials is added in an optimum composition to a 12-15 cm layer of soil in the sowing period.

EFFECT: invention improves aggregate composition, soil water capacity and increases nutrient content of soil.
