The present study deals with the spatial distribution and population density of earthworms in sewage area and garbage area and is related to the some of physical and chemical characters of soil. To investigate population densities of earthworms in relation to various physico-chemical variables of two municipal-sewage and garbage of urban environment. Certain species of earthworms, Lampito mauritti, Pontoscolex corethrurus grow abundant in well-humified soils with high C: N ratio, while some (Perionix excavatus) are most abundant in poorly humified soils with low C: N ratios. In tropical regions N-content is low in soil as compared to temperate regions. Availability of nitrogen appears to be one of the most important factors limiting earthworm’s population. The population density of earthworms in soil is regulated by abiotic and biotic factors over the seasons. The effects of various abiotic environmental variables such as rainfall, air temperature, temperature at the soil surface and 15 cm depth, soil moisture, pH available nitrogen, available phosphorus (P2O5) and potassium (K2O) on the seasonal population abundance and vertical distribution of earthworms in these urban sewage and garbage areas.
