Quality Vermicompost (Content N, P, K) from Beef Cattle Waste Treatment through Integrated

Abstract

This study aims to determine the effect of C/N ratio from feces of beef cattle and hay on the vermicomposting to quality vermicompost (content of N, P, K) through integrated processing. This study was conducted using Completely Randomized Design (CRD). Treatments were three treatment T1 = C/N ratio 20, T2 = C/N ratio 25, T3 = C/N ratio 30, with each 6 repetitions. Initial decomposition process conducted for 1weeks, vermicomposting process carried out for 2 weeks. Data were analyzed using analysis of variance and to determine the effect of treatments performed Duncan test. The results showed that: the C / N ratio signi cantly affect the content of N and P in vermicompost, and give effect non signi cant to K in vermicompost. The C/N ratio 20 produces the best quality vermicompost( N = 3.18%; P = 1.17% and K = 0.85%)
