The Effect of liquid organic fertilizer (LOF) goat biourin with various decomposers on some chemical properties of ultisol

Abstract

This study aims to improve soil quality, so that the soil used can be maintained against theavailability of soil nutrients. Efforts are made to apply fertilizers that are in accordance withthe needs of plants and in a balanced manner. Organic fertilizer is one of the efforts toimprove the physical and chemical properties of the soil, so that it is expected to increase thegrowth and production of plants to be applied. Liquid organic fertilizer has many advantages, namely the ease of application to soil and plants, all you need to do is water it. The rawmaterial forliquid organic fertilizer from goat biourin is goat urine, while the decomposersare banana hump, feces and EM4. This researchwas conducted in a greenhouse, was carried out for 4 months, Departmet of Soil and Laboratory of Chemistry, Biology and Soil Fertility, Department of Soil, Faculty of Agriculture, Sriwijaya University. The study using acompletely randomized design with 4 treatments and 3 replications. The treatment consistedof the ratio of biourin to water, namely: A (control), B (l:l), C (1:2), and D (1:3). Parametersobserved and measured in this study were C/N Ratio, Total N, and soil pH. Based on theresults of the study, it was concluded that the type and dosage of goat Biourin liquid fertilizer could increase soil pH, N-total and C/Nratio.
