Abstract: The present investigation was carried out in Nilona micro watershed of Darwha block, Yavatmal district, Maharashtra to study the physico-chemical properties of soils and also predict the hydrological behavior i.e. saturated hydraulic conductivity (K_s). 118 surface soil samples were collected from grid points located at regular interval of 325 m. The results showed that the bulk density of 1.25 to 1.68 g cm^-3 and particle density 2.40 to 2.81 g cm^-3. Porosity of 32.86 to 52.30%. In soils of the Nilona micro watershed, the amount of sand, silt and clay content varied from 37.90 to 60.70%, 10.70 to 25.30% and 25.90 to 37.60%. The saturated hydraulic conductivity (K_s) of the studied soil positively correlated with sand. The soils of Nilona micro watershed were saline in nature and were within safe limit of salinity. The organic carbon content of surface soils ranged from low to high and available nitrogen under low category. The present study helps to prepare a comprehensive watershed development plan to understand the topography, erosion status and drainage pattern of the region. The need of such information is important in estimating soil hydrological model that assumes particular importance for Yavatmal district, a drought prone region of Maharashtra.
