SOIL CONDITIONER Russian patent published in 2015 - IPC C05F11/00 C09K17/00 

FIELD: chemistry.

SUBSTANCE: invention relates to agriculture. A soil conditioner in granular form includes mineral components using an ash-slag mixture and lime, wherein the conditioner is made of irregularly shaped granules with grain size in the range of 1.0 to 6.0 mm of a water-resistant porous conglomerate with density of 300 to 400 kg/m³ and porosity structure, having a capillary and a non-capillary form, with ratio thereof of 0.85:1; the conglomerate consists of a dry mixture which is treated by mixing with water to a consistency with water to dry mixture ratio of 0.75:1, wherein the dry mixture contains biofuel ash as the ash-slag mixture, as well as cement, unslaked lime and a blowing agent. All components are taken in a defined ratio.

EFFECT: invention reduces density of soil consistency, increases soil porosity, increases aeration, increases moisture-retention capacity, which ultimately increases crop yield.
