NOVELTY - Preparing organic compound fertilizer, involves (a) mashing agricultural organic waste, (b) mixing swelling agent with agricultural organic waste, placing the mixture in bulking machine to prepare the pellet, and cracking the pellet to obtain thin powder, (c) forming a fermenting material with e.g. thin powder, and wheat bran, (d) mixing the fermenting material and transferring mixture to fermentation pond, (d) drying the fermented material and cracking product to obtain powdery mixture, and (e) subjecting the fertilizer mixture to extrusion and pelletization.    USE - The method is useful for preparing organic compound fertilizer.    ADVANTAGE - The organic compound fertilizer has high beneficial active and live bacteria, provides balanced nutrition to crops, removes pollution of chemical fertilizer and pesticide to the ground and product by strong fermenting and decomposing capacity of bacteria, improves soil to reach green and organic standard, and can be used in soil for a long period of time to increase yield and improve quality of the crops.    DETAILED DESCRIPTION - Method for preparing organic compound fertilizer by fermenting agricultural organic waste, involves (a) mashing agricultural organic waste, controlling the moisture content of the mashed product to 55-65% and obtaining 1-2.5 cm as segment, (b) mixing swelling agent (2.5-4.5%) with the agricultural organic waste, placing the mixture in bulking machine, controlling the temperature at 200 degrees C, and pressure to 10 kg/cm2, bulking the obtained product to prepare the pellet, cracking the pellet using cracking machine and sieving the obtained product to obtain thin powder having diameter of 1.0 mm or less, (c) forming a fermenting material with bulked thin powder (55-60), wheat bran (5.5-6.5), biological humic acid (0.4-0.6), effective microorganism (EM), preferably bacteria (15-26), zinc sulfate (0.4-0.5), ferric sulfate (0.9-1), ammonium nitrate (1.8-2), ammonium phosphate (0.9-1), boron (0.2-0.3) and calcium chloride (0.03-0.04), (d) stirring and mixing the fermenting material, transferring obtained material to the fermenting pond, piling the material in the fermenting pond for 1 m high, covering the piled material with air permeable insulating material, controlling the fermenting temperature to 30-35 degrees C in a segment manner, where the fermenting time is 10 to 14 days, the pH of the fermenting process is 5 to 6.5, and reducing the pH to 4.5 to 4.7 before removing the film, and stabilizing the venting amount in the fermenting period, (d) drying the fermented material to obtain a fermented material having water content of 10-12, where the temperature of the obtained product is 90 degrees C or less, and cracking the fermented product to obtain powdery organic compound fertilizer mixture, and (e) extruding the organic compound fertilizer mixture in the dry type extruding and pelletizing machine as the granular organic-inorganic compound fertilizer.
