NOVELTY - Method of producing organic fertilizer by using agricultural waste involves using fresh excrement diluent, straw grain and corn cob grain as raw materials, and mixing the raw materials with fermented bacterial liquid I after pretreatment, the temperature rises to 60-70 degrees C and keeping the temperature to ferment for 2-3 days, when the temperature is reduced to 40 degrees C, adding second mixing fermented bacterial liquid and mixing with the yeast uniformly, continuing to ferment for 5-8 days, air drying or drying the ferment material.    USE - For producing organic fertilizer (claimed).    ADVANTAGE - The processes makes full use of agricultural waste; changes waste into valuable, after fermenting; eliminates the straw and cow dung pathogen; obtains organic matter of the organic fertilizer and NPK content are high, organic fertilizer has more than 55% of organic substance content, NKP has more than 3%, water content is not more than 15%; and improves the soil property and crop yield.    DETAILED DESCRIPTION - Method of producing organic fertilizer by using agricultural waste involves using fresh excrement diluent, straw grain and corn cob grain as raw materials, and mixing the raw materials with fermented bacterial liquid I evenly after pretreatment adding water in the following steps: (1) obtaining pre-processed fresh excrement diluent, straw grain and corn cob grain as raw materials; (2) uniformly mixing the pretreated compost every day turning the first time and keeping the humidity greater than 40%, when the temperature rises to 60-70 degrees C, keeping the temperature and fermenting for 2-3 days; (3) when the temperature of the fermentation material drops to 40 degrees C, adding the second mixing liquid and mixing with the yeast uniformly, each turning for 2-3 times, keeping the humidity is more than 40% and ventilation condition, continuing to ferment for 5-8 days; and (4) after the fermentation process, the fermentation material to air-drying or drying the moisture less than 15%, and then screening the yeast material, with big grain diameter continuously as fermentation raw material carrier and continuously used after mixing with the raw materials.
