The Goat Liquid Fertilizer (Biourine) Quality by Addition Various Types of Decomposers to Support Organic Agriculture

Abstract

Excessive use of inorganic fertilizers causes several problems in the soil and can pollute the water so that the natural balance becomes disturbed. The use of inorganic fertilizers to increase crop productivity can be suppressed by switching to organic fertilizers. This study aims to determine the physical and chemical quality of goat’s liquid fertilizer (biourine) with the addition of various types of decomposers. The materials used in the study were goat urine, EM-4, banana hump, and goat feces. This study used a completely randomized design with 4 treatments with 3 replications consisting of P0 (1 liter of goat urine), P1 (1 liter of goat urine + 45 ml mole of banana hump), P2 (1 liter of goat urine + 45 ml mole of goat feces), P3 (1 liter goat urine + 45 ml mole EM-4). Parameters measured in this study were physical quality (odor, texture, pH, temperature and color) and chemical quality (nitrogen, water content, phosphorus, calcium and organic C). The results showed that the temperature in the P0 treatment was 34oC, while the P1, P2 and P3 treatments were 32oC. The color of the goat biourine in treatment P0 is reddish black and treatment P1, P2, P3 is concentrated reddish black. The smell of goat biourine treatment P0 was very stinging and treatment P1, P2, P3 was stinging. Treatment pH ranged from 7.67-8.29
