Abstract

The purpose of the research was to granular organic fertilizer from agricultural wastes. Mineral nutrient ( N-P-K-Ca-Mg content) of Peanut husk, Peanut Stem, Rice straw, Black rice hull, Rice Bran, Cabbage, Chinese Kale, Chinese Cabbage, Swine manure, Poultry Manure and Bat Manure were analyzed. The concentrations of the mineral nutrients in Peanut husk were N =1.52%, P = 1.59% , K = 2.6 %, Ca = 10.25% and Mg = 0.94%, Rice Bran, N =1.67%, P = 0.08%, K = 0.63%, Ca = 8.97% and Mg = 1.08%, Swine manure, N =1.15%, P = 4.26%, K = 0.21%, Ca = 1.29 % and Mg = 0.34 %, Poultry Manure N =1.38% , P =5.39%, K = 1.84 %, Ca = 5.75 % and Mg = 0.64%, Bat Manure, N = 2.10 %, P =13.89%, K =1.10%, Ca= 1.30% and Mg= 0.90%, Black rice hull N = 0%, P= 0.11%, K= 0.67%, Ca= 3.04% and Mg= 1.09%. respectively, Study of the a ratio of granular organic fertilizer found that a ratio of 18:32:20:20:4:6 (By percentage) and mixed with binder material (Molasses). The granular organic fertilizer were analyzed. The result were : N = 1.75 % , P =1.66 %, K = 1.01 %, Ca = 8.34 %, Mg = 2.56%, OC = 32.05 %, OM = 59.23 %, pH = 6.3, EC = 3.4 dS/m and C:N ratio= 18:1
