Production process for converting cassava wastes into organic fertilizer

The invention discloses a production process for converting cassava wastes into organic fertilizers, comprising the following steps: (1) precrushing waste stems, branches and leaves of cassava; (2) adding inorganic nitrogenous and phosphorus fertilizers and yeast into the waste materials for pile-fermentation, and then mechanically turning over piles and drying till the water content of the waste materials is between 10 percent to 20 percent; and (3) conveying the dried fermented waste materials into a mixer, mixing the dried fermented waste materials with nitrogen, phosphorus and potassium fertilizers, and then pulverizing, pelletizing by extrusion, drying in a drum and packaging to obtain finished products. Because waste stems, branches and leaves after cassava reaping are processed into organic fertilizers, the waste materials are fully utilized and changed into valuables, and the problem of the environmental pollution of the waste materials is also solved.
