ARTIFICIAL SOIL AND METHOD OF ITS PREPARATION Russian patent published in 2015 - IPC C05F11/08 C05G3/00 

FIELD: agriculture.

SUBSTANCE: group of inventions relates to agriculture. The air biosoil - an artificial soil consists of large clumps of 2-10 mm in size, uniformly distributed over the volume, the small clumps of 0.1-0.3 mm in size, and the ultrafine clumps of up to 10 microns, with a total porousness of at least 40%, with a content of organic matter of not less than 20%, the acidity of pH 6-8, having a colour from light brown to black, containing microflora characteristic to wild black soil. The method of air biosoil preparation consists in the fact that waste products of animals and other organo-mineral wastes are mixed, peat, scanty soil and other filling materials are added, the resulting mixture is crushed to obtain at least 40% of small clumps, 1-5% of mixture is selected and passed through a disintegrator to obtain ultrafine clumps, they are mixed with the rest of the mixture, the concentrated soil solution is added in an amount of 1-3% by volume of the mixture, then the sorbent additives are added to provide porousness of at least 40%, the mixture is stirred by pouring to the containers with the displaced centre of gravity to ensure homogeneity , the mixture is placed into a fixed container and maintained at an optimum temperature within 20-37°C for at least 24 hours.

EFFECT: invention enables to increase the humus content and to improve productivity of creating soil from wastes.
