Conversion of castor shell into a value added compost
Keywords:
Castor, Castor shell, Compost, NutrientAbstract
Castor shell is rich in lignin material and takes a long time to decompose. Therefore, it is necessary evolve procedures that can hasten this process so that the shell could be used as compost. The compost heaps were prepared in four treatment combinations (T1: castor shell + 10% dung slurry; T2: castor shell + dung slurry + 2% urea solution + 0.5% SSP; T3: castor shell + dung slurry + microbial consortium @ 1 kg/t; and T4: castor shell + dung slurry + 2% urea solution + 0.5% SSP + microbial consortium @ 1 kg/t. The N (1.2%) and P (1.4%) in T4, and K (1.5%) T1 were maximum. Micronutrients, Fe (4000 ppm) in T3 and Zn (68 ppm) in T4 were maximum.
