NOVELTY - Organic-inorganic fertilizer for turf, comprises (in parts mass): fermented organic fertilizer (50-65), urea (5-10), ammonium sulfate (10-20), diammonium phosphate (5-10), potassium chloride (5-10), magnesium sulfate (3-5), ferrous sulfate (2-5) and nitrification inhibitor (0.02-0.15), where the fermented organic fertilizer is obtained by fermenting sludge (50-60) with fungal dreg (20-30) and fungicide (15-20) obtained by microbial fermentation, and then drying the fermented product, until the moisture content is 25-35 wt.%.    USE - The organic-inorganic fertilizer is useful for turf and improving soil fertility.    ADVANTAGE - The fertilizer has long-lasting effect and supplies nutrients uniformly. The turf quality is improved.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of preparing the organic-inorganic fertilizer, which involves (a) fungicide obtained by microbial fermentation is prepared by mixing (in parts weight) horse manure (8-15) with extraction residue (5-8) and fungal dreg (80-85) uniformly, adjusting moisture content of the mixture to 60-65 wt.% and pH to 7-7.5, covering the mixed material using plastic film and fermenting for 3-5 days, when the temperature of windrow rises to 50 degrees C, turning and then fermenting again for 3-5 days to obtain first-grade solid fungicide, mixing the first-grade solid fungicide (15-25) with sludge (70-80), calcium superphosphate (3-4) and potassium chloride (1-2) uniformly, and fermenting the mixture to obtain the microbial fungicide, (b) fermented organic fertilizer is prepared by mixing (in parts) sludge (50-60) with fungal dreg (20-30) and fungicide (15-20) obtained by microbial fermentation uniformly, adjusting moisture content of the mixture to 60-65 wt.% and carbon/nitrogen mass ratio to 23-28 and pH to 7-7.5, composting the mixed material, punching a hole from the top, where the number of holes is 10-15/m2, covering the mixed material using plastic film for aerobic fermentation, fermenting for 7-10 days, when the temperature of the windrow rises to 50 degrees C, turning the mixture and fermenting the mixture again for 5-6 days to finish the fermentation process, and drying or blow drying the fermented organic fertilizer, until moisture content of the mixture is 25-35 wt.%, (c) mixing the fermented organic fertilizer with urea (80 meshes), ammonium sulfate, diammonium phosphate, potassium chloride, magnesium sulfate, ferrous sulfate and nitrification inhibitor uniformly, transferring the mixture into a disc or rotary drum granulator, spraying aqueous carboxymethylcellulose solution (2 wt.%) on the mixture, granulating the obtained mixture, and drying and screening the granules.
