NOVELTY - A cassava residue fertilizer for sugarcane comprises: 80-150 pts. wt. cassava residue, 30-50 pts. wt. tea leaves, 5-10 tea residue, 30-50 pts. wt. inorganic fertilizer, and 10-20 pts. wt. microorganisms. The inorganic fertilizer comprises 10-20 pts. wt. nitrogen fertilizers, 10-15 pts. wt. calcium superphosphate and 10-15 pts. wt. potash fertilizers. The microorganisms comprises Bacillus including Bacillus megaterium, Lactobacillus acidophilus, lactobacillus azotobacter and Bacillus subtilis.    USE - As a cassava residue fertilizer for sugarcane (claimed), used in agricultural industry for crop planting.    ADVANTAGE - The fertilizer promotes growth of sugarcane; reduces or avoids the use amount of heavy metal; and has increased absorption utilization rate.    DETAILED DESCRIPTION - A cassava residue fertilizer for sugarcane comprises: 80-150 pts. wt. cassava residue, 30-50 pts. wt. tea leaves, 5-10 tea residue, 30-50 pts. wt. inorganic fertilizer, and 10-20 pts. wt. microorganisms. The inorganic fertilizer comprises 10-20 pts. wt. nitrogen fertilizers, 10-15 pts. wt. calcium superphosphate and 10-15 pts. wt. potash fertilizers. The microorganisms comprises Bacillus including Bacillus megaterium, Lactobacillus acidophilus, lactobacillus azotobacter and Bacillus subtilis. The nitrogen fertilizer includes ammonium hydrogen carbonate and ammonium nitrate having mass ratio of 1:1-1.5. The potash fertilizer includes potassium chloride and potassium nitrate having mass ratio of 1:1-1.5. An INDEPENDENT CLAIM is included for preparation of the fertilizer involving using manioc waste to ferment, drying the cassava slag until the water content is 50-60%, adding microorganism, sealing the composition for 10-15 days, fermenting cassava; fermenting tea leaf, taking tea leaf, where the pH of soil is 5-5.5, mixing uniformly, adding nitrogen fertilizer and microorganism, fermenting for 15-29 days, carrying out aerobic fermentation for 10-15 days, to obtain primary product fertilizer; drying the primary product fertilizer, until the water content is 5-10%, crushing, grinding by 80-100 meshes sieve, and proceeding spray granulation to obtain the fertilizer.
