METHOD TO OBTAIN HUMOUS-MINERAL FERTILIZER

摘要

agriculture. SUBSTANCE: the mixture of peat and aqueous solution of caustic alkali is heated up to 80-130 C. The mixture obtained is divided into two flows: the larger flow - 60-90% against total weight and the smaller one - 10-40%, correspondingly. Slaked lime, sulfuric or phosphoric acids and zinc compounds are introduced into the larger flow. Mixture's pH is made to be 6.5-7.5, then it is mixed with the smaller one. It is possible to add NPK-fertilizers and/or carbamide into the larger flow. EFFECT: widened assortment of humous-mineral fertilizers of meliorative action. 2 cl
