FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. Complex soil granular bio-preparation contains microelements and polymer, and also contains pathogens effective microorganisms immobilized on a granular inert carrier, part of the immobilized microorganisms within the granules is treated with water-soluble polymer with the formation coated with a polymer shell of slowly and rapidly dissolving capsules having different thicknesses of the polymeric shell, the thickness of the polymeric shell of the capsules is not less than 5 microns, slowly soluble – no more than 10 microns, the bio-preparation consists of a complex of granules, quickly soluble and slowly soluble capsules, taken in the ratio 1:1:1, and as microorganisms contains combinations of strains of fungi and/or bacteria.
EFFECT: invention makes it possible to expand the functionality of the preparation and to increase the efficiency of plant protection from diseases caused by pathogenic microflora, and also to increase the efficiency of the biological preparation and improve the soil structure.
