METHOD FOR RECOVERY AND IMPROVEMENT OF SOIL FERTILITY, ESPECIALLY IN DESERT AND SEMI-DESERT AGRICULTURAL REGIONS Russian patent published in 2017 - IPC A01B79/02 

FIELD: agriculture.

SUBSTANCE: method for recovery and improvement of soil fertility is carried out by adding organic and natural mineral materials to the topsoil in the waiting period and saturating it with water in the postharvest period. The poultry manure is preferably used as an organic material and the sodium bentonite is used as a mineral material. First pre-processing of poultry manure is done using the Oksizin enzymatic drug synthesized from sugar beet molasses and providing for decomposition and disinfection of the organic material. The sodium bentonite designed for water filtration and evaporation rate reduction in the topsoil is ground. Then the produced materials are applied to the topsoil, mixed with the topsoil, buried in the depth of the plant arable layer selected for cultivation. The result is a shielding layer that provides for starting conditions of the microbiocenosis development. After sowing or planting in the plant shielding layer its regular watering is carried out. The first irrigation water is added with the Agrozin enzymatic drug synthesized from sugar beet molasses and providing for increased activity of aerobic soil bacteria in the plant rhizosphere.

EFFECT: invention allows for the efficient development of biocenosis and recovery and improvement of the topsoil fertility.
