The Effect of Bio-fertilizer on Soil Chemical Properties of Sugarcane in Purwadadi Subang
Abstract
Biofertilizer is a biological product that can be used to improve the soil fertility. It is useful in enriching soil with micro-organisms that produces organic nutrients and may also reduce the plant diseases. This experiment investigates the usefulness of biofertilizer which can increase the soil properties. This study was conducted at sugarcane plantation, Purwadadi Subang Bandung. The experiment was arranged in a Randomized Block Design (RBD) with 6 treatments and 4 replications. The treatments were (50 ; 25) g/treatment Biofertilizer + (¼ ; ½ ; ¾ ; 1) of the recommended dose of NPK and the recommended dose of NPK as a control. The chemical properties (potential K, K sorption, potential P, P sorption, total N and pH) were affected by biofertilizer application, except for N sorption. The best treatment from this product was combination from high level of biofertilizer (50 g) and (1/2 - 1) of the recommended dose of NPK. The application of biofertilizer can substitute NPK fertilizer 25% - 50% in soil. In general, this product has a good potency especially to increase some of soil chemical properties in a short time with simple application in the field.
