NOVELTY - Organic fertilizer comprises 65-70 wt.% chicken manure, 16-20 wt.% tobacco waste, 8-12 wt.% conditioning agent, 1-2 wt.% pH regulator, 3-5 wt.% deodorizing agent, and 0.1-0.2 wt.% microbial fermentation agent. The conditioning agent is radix Sophorae flavescentis residue, bean dregs, garlic slag, pepper waste, humic acid, sawdust, rice hull, and/or edible mushroom. The pH regulator is natural gypsum, diluted hydrochloric acid, diluted sulfuric acid, and/or calcium phosphate. The microbial fermentation agent is fermenting bacteria.    USE - Organic fertilizer.    ADVANTAGE - The organic fertilizer has comprehensive nutrients, thus, compensating for the shortage of fertilizer.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of organic fertilizer comprising raw material processing by crushing tobacco waste, edible mushroom dreg, and other organic material, mixing with chicken manure by stirring, adding microbial fermentation agent and deodorizing agent, measuring the pH of the mixed material, adding pH regulator to regulate the pH at 6.5-7.5, where the ratio of carbon and nitrogen is 25-35:1, and obtaining fermentation material, conveying the fermentation material to a fermentation tank, sealing, fermenting for 5-7 days, turning for the first time when the temperature increases to 60-70 degrees C, turning for 3-4 times for every 3 days to fully ferment, where fermenting temperature of chicken manure is 40-70 degrees C, obtaining fermented material, when the fermentation material temperature increases to 60-70 degrees C, adding conditioning agent, conducting fully sealed fermentation for 4-7 days, controlling the fermentation temperature at 70 degrees C, turning for 2 times, controlling the water content at 40-50%, where the weight ratio of fermented material and conditioning agent is 6:4, scattering the materials and naturally cooling by evaporating water, when the material temperature reduces to normal temperature and the water content of the material is less than or equal to 30%, the fermentation is complete, and obtaining organic fertilizer.
