METHOD OF PRODUCTION OF ECOTERRA ORGANIC FERTILIZER OF ECOTERRA-T AND ECOTERRA-ZH BRANDS Russian patent published in 2024 - IPC C05F11/08 C05F17/20 

FIELD: agriculture; agricultural production; horticulture; floriculture; forestry and urban farming.

SUBSTANCE: in the method, organic livestock waste of hazard classes III-IV is placed on equipped sites in open piles and a microbiological preparation in the form of effluent from biogas stations is introduced into them by spraying with equipment. Moisture-absorbing material in the form of sawdust, straw, peat and compost is first delivered to the site and levelled over the surface of the site with a layer of at least 10 cm. Organic livestock waste of hazard classes III-IV in the form of cattle manure, bird droppings, pig manure, horse manure, the moisture content of which does not exceed 75% is unloaded to moisture-absorbing material either jointly or separately. The organic mass is mixed and formed into a triangular shaped pile. The microbiological preparation is applied by spraying with equipment 3 or 4 times with intervals between the applications of 10–14 days in an amount of 2–4 litres per 1 m² of the surface of the pile. The resulting mixture is subjected to natural composting in the warm season for at least 30 days, and in the cold season for at least 60 days. At the same time, the placement site is equipped with waterproofing means — a water seal and a filtrate drainage system.

EFFECT: method provides a reduction in waste processing time, versatility in raw materials, the use of microbiological preparations produced on the basis of processed waste in reactors of biogas stations with anaerobic conditions, a simplified processing procedure with no need for turning the pile and the use of special equipment for introducing biological products.
