Abstract
In recent years livestock sector in Indonesia grows rapidly. As a consequence, organic waste will increase and cause environmental pollution and health problem if it’s not managed. The recycling of cattle manure for agriculture purpose can waste problem. Previous studies have suggested that the use of organic waste as bio-fertilizer is good for soil. The objective of this study was to investigate the difference between untreated and treated cattle manure on their chemical properties, especially nutrient elements. Untreated cattle manure, treated cattle manure by anaerobic digesting and composting were analyzed their chemical properties such as pH value, water and organic content, N-content, P2O5, and K2O concentration. The pH value of fresh cattle manure, buried cattle manure, biogas sludge, and compost were 6.8; 5.4; 6.8; and 6.9 respectively. The C organic content in treated cattle manure decreased as compared to untreated cattle manure. On the other hand, N-content, P2O5, and K2O concentration of treated manure were higher than untreated manure. The highest N-content, P2O5, and K2O concentration were performed by compost from cattle manure.
