NOVELTY - Method for preparing organic and inorganic fertilizer, involves steaming aqueous mother liquid containing amino acid, filtering, adding calcium, magnesium, copper, iron, manganese, zinc, boron, other organic matter and molybdenum, mixing, performing chelation reaction, adding lignin, stirring to obtain a liquid mixture, milling dried chicken manure, adding organic manure, fermenting, stirring, drying, mixing with humic acid, monoammonium phosphate and potassium sulfate, mixing, grinding, adding the liquid mixture, mixing, granulating, and drying product.    USE - The method is useful for preparing organic and inorganic fertilizer in form of granule (claimed) which is used for promoting growth of field crops, fruit and vegetable.    ADVANTAGE - The method prepares fertilizer which is rich in nutrient content, satisfies nutritional requirement of crop, improves nutritional content of soil, activates soil and improves quality of the agricultural products.    DETAILED DESCRIPTION - Method for preparing organic and inorganic fertilizer, involves taking raw materials comprising 80% aqueous mother liquid comprising amino acid, 10% amino acid, 10% other organic matter, 0.20% calcium, 0.20% magnesium, 0.1% copper, 0.2% iron, 0.1% manganese, 0.05% zinc, 0.1% boron, 0.05% molybdenum, sodium hydroxide solution (suitable quantity), 1% lignin, 21-23% chicken manure, 33-35% distillers grains, 1% organic manure fermentation agent, 1% UV sterilizing deodorant, 3% humic acid, 9% monoammonium phosphate and 8% potassium sulfate, placing the aqueous mother liquid in a concentrated tank, steaming at 80-85 degrees C for 6-8 hours until moisture content reaches 30%, filtering, placing into a chemical reactor, heating using microwave at 75-85 degrees C, blending, adding trace amount of calcium, magnesium, copper, iron, manganese, zinc, boron, other organic matter and molybdenum, mixing uniformly, performing chelation reaction, regulating pH to 5-7 using sodium hydroxide solution, after 6-7 hours, adding lignin, stirring for 0.2 hours to obtain a liquid mixture, milling dried chicken manure, placing into a fermentation tank, adding the organic manure, fermenting for 20-22 days, adding the UV sterilizing deodorant, stirring, drying until moisture content of less than 3%, to obtain dried organic fertilizer, mixing the dried organic fertilizer with the remaining raw materials, mixing uniformly, grinding into powder, adding obtained liquid mixture, mixing uniformly, granulating, and drying using dryer at 55-60 degrees C for 1.5-2 hours to obtain product.
