Physico- chemical properties of soil have profound influence on soil enzyme acid phosphatases activity. To study the distribution of soil enzyme acid phosphatase and influence of physico- chemical properties on soil enzyme acid phosphatases activity forty soil samples were collected from different villages of Ranga Reddy district of Telangana state. These samples were analysed for the physicochemical properties like pH, EC, available nutrients, texture and organic carbon and soil enzyme activity was assayed. Acid phosphatase activities of the soil expressed as µg of 4-nitrophenol released g-1 soil h-1 ranged from 18.93 to 51.2 with an average value of 31.79. The pH ranged from 5.7 to 8.9, electrical conductivity from 0.1 to 1.23 dSm-1 and organic carbon from 0.13 to 1.48 %. The available Nitrogen varied from 201.5 to 472.5 kg ha-1. The available P2O5 status in the soils varied from 11.6 to 79.1 kg ha-1. The range of available K2O ranged from 118 to 411 kg ha-1. Acid phosphatase significantly, positively correlated with organic carbon (r = 0.735**) and available P (r = 0.776**). Acid phosphatase activity did not show any significant correlation either with silt, clay and pH.
