【 摘 要 】

The purpose of this research is to know the chemical nature of liquid organic fertilizer (LOF) based on various organic wastes and their effect on soybean growth. The study was conducted using a randomized block design with 9 treatment of LOF type applications. made from water hyacinth waste and a variety of additional composition of other organic wastes. Each of these treatments was repeated 3 times, requiring 27 experimental plots each with an area of 18 m2. The parameters observed were the chemical properties of LOF and the growth of soybean crop (plant height, number of leaves). The data obtained were analysed by analysis of variance when there was real difference, then continued with Least Significant difference (LSD test) 5%. The results showed that LOF contained some essential nutrients needed by plants, it is containing Nutrition Plants: N, P, and K, with C / N ratio: low. In addition also contains various bacteria that can improve the growth of soybean crops. Application of LOF in the field of agriculture can also prevent the occurrence of land degradation, as well as a solution in overcoming the problem of organic waste.
