Application Organic Fertilizer to Improve Soil Properties in Intensive Farming System on Upstream Part of Bedadung Watersheed

Abstract

The chemical fertilizers and pesticides used on the soil will lead to compaction and reduce the number of soil organisms. Compaction and soil organisms decrease indicated the physical and chemical quality of the soil decreases. The research aimed to analyze the application of organic fertilizer and organic pesticide in intensive farming systems in order to change soil quality to
calculate of the level erosion hazard and productivity of chili plants. The research was carried out upstream of Bedadung Watershed. The experimental design used a Randomized Block Design (RBD) with two-factor. The observation of variables for soil quality parameters is soil structure, soil texture, soil permeability, and B-Organic. Whereas the observed plant productivity consisted of plant height (cm), number of leaves (strand), and yields (grams). The treatment of organic fertilizer also has an impact on changes in soil quality where the soil texture changes to sandy loam dominated by the percentage of fine sand and dust, the aggregate size of the soil structure increases, soil permeability become moderate - very slow, and organic material becomes high - moderate. Data on the height of plants and the number of leaves were analyzed using the Two Way of Anova test. The results of this study are that the most effective treatment for chili productivity is found in the treatment of 0.25kg organic fertilizer/plant and 11ml / liter of vegetable pesticides with a spray volume of 5.6 ml/plant producing an average value of 51.86 cm plant height, 31,2 strands of leaves and 59.39 grams of chilies.
