Organic carbon status of sewage irrigated soils of Prayagraj Uttar Pradesh

Abstract

The representative soil samples were collected randomly from three sewage irrigated sites in Prayagraj, namely Beligaon, Kulbhaskar Ashram P.G. College and Baxibandh. Soil sampling was carried out by random sampling and representative soil samples were collected from different depths (0-10 cm, 10-20cm and 20-30 cm). Average of soil organic carbon in the whole top layer (0.643%) was more than the bottom layer (0.60%) in different soil samples. The organic carbon content in each soil samples decreased with depth. Soil organic matter content in different sewage irrigated soils can be determined by using conversion factors with soil organic carbon content. The conversion factor is 1.724, therefore, the level of soil organic matter is 1.724 multiplied by the soil organic carbon. The purpose of this research paper is to know how much and at which annual rate soil organic carbon can be accumulated in soils in different sewage irrigated sites of Prayagraj.
