Effect of Soil Organic Carbon on Perviousness and Conservation Property of Soil
Abstract This study was carried to use organic based wastes, as a source of soil organic carbon (SOC) to artificially restore the SOC in soils and explore its effects on Soil perviousness and conservation property. This property is defined by the author to represent the combined effect of the factors like SOC, porosity (Po), infiltration (In), erosion (Er) and runoff (Ru). The SOC was quantified in humus, pressmud, bagasse ash and fly ash, which were used as amendments for the four soils namely black cotton (BC), red, marshy and mountainous soils that prevail in the study area. The experiments were designed based on Response surface methodology with central composite design with respect to soil perviousness and conservation property. Quadratic models were developed to correlate soil-amendment combinations for the factors. For each soil a polynomial equation was built by combining all the factors for this soil property. Fly ash for BC soil, bagasse ash for red, marshy and mountainous soil were found to be the best suited soil-amendment combinations in enhancing the property of soil conservation and perviousness. The optimum SOC dosages were 1.005, 0.72, 0.76, and 0.86 g/g of BC, red, marshy and mountainous soils respectively.
