NOVELTY - Preparing composite fertilizer involves preparing fat absorption matrix by mixing carbonized wood residue (1 pts. wt.) with perlite (6-10 pts. wt.). Obtained mixture is heated at 60-65 degrees C for 10-15 minutes. Cooling and grinding heated product to obtain a fat absorption matrix of particle size 400 mesh, where perlite is preheated at 1000-1300 degrees C to obtain a porous material. Fertilizer matrix is prepared by mixing starch (1 pts. wt.), and clay powder (45-55 pts. wt.) to obtain another mixture. Obtained mixture is ground to obtain fertilizer matrix of particles size 200 mesh.    USE - Method for preparing composite fertilizer (claimed).    ADVANTAGE - The method enables to prepare organic fertilizer in cost -effective and eco-friendly manner.    DETAILED DESCRIPTION - Preparing composite fertilizer involves preparing fat absorption matrix by mixing carbonized wood residue (1 pts. wt.) with perlite (6-10 pts. wt.). Obtained mixture is heated at 60-65 degrees C for 10-15 minutes. Cooling and grinding heated product to obtain a fat absorption matrix of particle size 400 mesh, where perlite is preheated at 1000-1300 degrees C to obtain a porous material. Fertilizer matrix is prepared by mixing starch (1 pts. wt.), and clay powder (45-55 pts. wt.) to obtain another mixture. Obtained mixture is ground to obtain fertilizer matrix of particles size 200 mesh. Fertilizer pro-matrix is prepared by mixing soil with pepper roots to obtain third mixture, which is ground to obtain final product of 100-mesh sieve. Organic fertilizer is prepared by mixing pepper powder (9-11 pts. wt.) with animal waste (45-55 pts. wt.) to obtain fourth mixture. Obtained mixture is fermented for 40-45 days to obtain organic fertilizer. Moisture content of animal waste is 30-40%, and particle size of pepper powder is 2mm. Baking powder (10 pts. wt.), and sugar (100 pts. wt.) are dissolved in water at 60 degrees C. Dissolved product is mixed with rice bran (50 pts. wt.), tea residue (50 pts. wt.), soybean meal (39 pts. wt.), and yeast (1 pts. wt.) to obtain fifth mixture. Obtained product is mixed with absorption release matrix material (1 pts. wt.), fertilizer matrix (1 pts. wt.), fertilizer pro matrix (1 pts. wt.), and organic fertilizer (7-13 pts. wt.) to obtain seventh mixture. Obtained product is mixed with nitrogen, phosphorus pentoxide, and potassium oxide in a ratio of 6:5:4:85 to obtain eighth mixture. Obtained product is granulated to obtain final product.
