METHOD FOR PREPARING LIQUID ORGANOMINERAL FERTILIZER FROM CHITOSAN-CONTAINING RAW

摘要

FIELD: agriculture, fertilizers.;SUBSTANCE: method involves treatment of cyst crayfish, Artemia salina, with alkali 50% solution at the room temperature and modulus value = 1-(5:10) for 3-4.5 days, its treatment with phyto-nontoxic acids to pH = 3.0-6.3 followed by addition of copper sulfate to the solution in the amount 0.001-0.01 wt.-%. Ortho-phosphoric and sulfuric acids are used as mineral phyto-nontoxic acid mainly. Acid extract from humin-containing substance (peat, biohumus or sapropel) is used as an organic phyto-nontoxic acid, and potassium hydroxide is used as alkali mainly. Method provides preparing liquid organomineral fertilizer with enhanced biological activity. Invention can be used in plant growing, forest farming and fruit growing for improvement and sanitation of soils and enhancing productivity of agricultures.;EFFECT: improved method for preparing, enhanced and valuable properties of fertilizer.;5 cl, 3 ex
