METHOD FOR OBTAINING ORGANIC FERTILIZER BY PROCESSING DEBARKING WASTE Russian patent published in 2021 - IPC C05F11/00 C05F11/08 C05F17/20 

FIELD: fertilizer production.

SUBSTANCE: invention relates to a method for obtaining fertilizers based on debarking waste. The method for obtaining organic fertilizer by processing the waste of debarking includes grinding the debarking and subsequent laying in clamps together with chicken droppings and their subsequent composting, while the formation of clamps is carried out by evenly laying layers of debarking and chicken droppings alternately. The laid layers alternate at least twice, while the ratio of debarking waste and chicken manure by weight in the clamp is 50/50. After laying each layer, a 10% solution of the microbiological fertilizer Baikal EM1 is sprayed on each laid layer and then composting is carried out for 3 weeks with mixing of the formed clamp with a frequency of 1 time a week.

EFFECT: proposed method for obtaining organic fertilizer by processing debarking waste provides organic fertilizer that is safe for direct application to the soil, provides increased decomposition of organic matter contained in debarking waste and chicken manure, provides restoration of the humus layer of the soil, makes it possible to process bark dumps and bird droppings on an industrial scale, which improves the ecological state of the environment in regions with a developed woodworking industry.
