METHOD FOR PRODUCTION OF FERTILIZING/MELIORATING COMPOSITION BASED ON CARBONATE SAPROPEL Russian patent published in 2006 - IPC C05F7/00 C05F3/00 

FIELD: agriculture, in particular fertilizer production and soil fertility enhancing.

SUBSTANCE: claimed method includes composting in clamps of frozen sapropel, organic waste and NPK mineral fertilizers. Frozen carbonate sapropel is treated with hydrogen peroxide in ratio of 10:1 calculated as dry matters, humidity of organic waste is adjusted to 60-65 %, blended with sapropel in ratio effective to produce optimum pH value (6.5-7.5) and mineral fertilizers are added. Then mixture is stowed in clamp, treated under stirring with soil microorganism composition in amount of 1 l per 1 t of mixture at humidity of 60-65 % and temperature and conditioned for 1 week. After secondary stirring mixture is further conditioned for 2 weeks at temperature not more than 30°C.

EFFECT: multipurpose mixture of high quality to enhance soil fertility.
