METHOD FOR PRODUCTION OF STIMULATING ORGANOMINERAL FERTILIZER Russian patent published in 1997 - IPC

FIELD: agriculture. SUBSTANCE: humine fertilizers and growth stimulators are prepared by mixing of ammoniated peat being enriched by microelements with fractions which are obtained by treatment of peat with solutions of alkali and hydrogen peroxide. Ammoniation of peat having 80 % moisture content is carried out at 80-90 C with the help of solution of ammonia and urea within 3-3.5 h. Mass ratio of peat and 10 % solution of ammonia is 1:0.4. Microelements and solutions being prepared during consequent treatment of said peat with 3 % solution of KOH within 10 h at 20 C and with 10 % solution of hydrogen peroxide within 1.5-2 h at 80-90 C are added into activated peat. Ratio of said peat, 3 % solution of KOH and 10 % solution of hydrogen peroxide is 1:12:2 respectively. At increased alkalinity of fertilizer 25 % solution of orthophosphoric acid is used. Quantity of thus activated peat in desired fertilizer is 20-50 mass %. EFFECT: increases biological activity of desire fertilizer. 1 tbl
