METHOD FOR OBTAINING A TAN BARK-DUNG FERTILIZER OF PROLONGED ACTION

摘要

agriculture. SUBSTANCE: the innovation deals with the methods for obtaining organic fertilizers. Tan bark waste products at about 7.5% moisture content reduced to 7-10 mm are mixed with poultry dung at about 76% moisture content at 1:2 weight ratio. The latter provides initial carbon-nitrogen content being at 20.3:1 ratio. Composting is carried out for up to 30 d. The present innovation enables to utilize waste products of both poultry- breeding and timber-processing enterprises. EFFECT: higher efficiency. 3 ex
