A detailed study was carried out with respect to soil organic carbon (SOC), pH and Cu, Fe, Mn, Ni, and Zn on agricultural soil used for paddy rice cultivation for many years. The accumulation of Cu, Fe, Mn, Ni, and Zn in the soil has been correlated with pH and the presence of the five metals. Basic statistics has been elaborately used to explain nthe results and pollution indices are calculated to estimate the degree of soil degradation. Principal component analysis was carried out to identify the factors responsible for the soil quality degradation. The results throw light on quality of the soil from a well-known agricultural ecosystem.
