NOVELTY - Chicken manure fermented organic fertilizer and its preparation are claimed. The fertilizer comprises 3000 kg chicken manure, 400-600 kg edible fungus waste residue, 100-200 kg soybean meal, 2-3 kg leavening agent and 20-30 kg yeast powder. Method for preparation of fertilizer, involves (a) weighing the above-mentioned raw materials, (b) mixing weighed raw materials, (c) piling mixed material, (d) performing two types of fermentation, where the first type fermentation is short stack fermentation, and the second type fermentation is high stack fermentation.    USE - As chicken manure fermented organic fertilizer.    DETAILED DESCRIPTION - Chicken manure fermented organic fertilizer and its preparation are claimed. The fertilizer comprises 3000 kg chicken manure, 400-600 kg edible fungus waste residue, 100-200 kg soybean meal, 2-3 kg leavening agent and 20-30 kg yeast powder. The chicken manure has water content of 60%. The edible fungus waste residue has water content of 10%. The soybean meal has water content of 6%. Method for preparation of fertilizer, involves (a) weighing the above-mentioned raw materials, (b) mixing weighed raw materials, (c) piling mixed material, (d) performing two types of fermentation, where the first type fermentation is short stack fermentation, and the second type fermentation is high stack fermentation. The short stack fermentation is performed by stacking mixed material in a short triangular section for 7-10 days, until water vapor basically disappears, where the triangular section is 45-50 cm in height and 100 cm in width, under summer conditions, short stacks doubled three times a day, and under winter conditions, short stacks doubled twice a day. The high stack fermentation is performed stacking mixed material to 25-300 cm tall as conical stacks, and fermenting mixture for 1-2 months, where if the material is only chicken manure, the mixture is stacked within 20 days before fermentation. An INDEPENDENT CLAIM is included for method for preparing the fertilizer, which involves performing the above-mentioned method.
