Soils in peri-urban areas may fall under diverse environmental backdrops. In majority of the areas, agricultural and industrial activities play a vital role in variability of physicochemical characteristics of soils. In the present study, soil samples were collected in different backdrops which include industrial, agricultural and coastal areas. Various Physicochemical parameters were analyzed to assess the status of soils in context with fertility and variability. To assess the soil variability, Coefficient of variation was used as an index. Overall results of the soil study implicate lower contents of organic carbon and phosphorus has been observed in all the environments. C.E.C indicated as very low to medium content in all the samples. Soils in all the environments were observed to be non-salinized with optimum range of sulphates, pH and conductivity. Total nitrogen varying from lower to slightly higher, exchangeable bases (Ca2+, Mg2+, Na+) were observed to be higher except potassium (K+) in all the soil samples. The present study results are useful as base line fertility status of soils and can be of use for future land management practices.
