To study the distribution of soil enzyme urease in some of the vegetables growing soils of Ranga Reddy District of Telangana State, as Ranga Reddy district is near to metropolitan city Hyderabad and most of the farmers are involved in growing vegetables and are supplying to the nearby city to various vegetable markets present nearby. Soil enzyme activity is influenced by physico- chemical properties on soil enzyme. The soil was analysed for the physicochemical properties and they were correlated with the urease enzyme activity in the soils. The soil samples were analysed for the physicochemical properties like pH, EC, available nutrients, texture and organic carbon and soil enzyme activity was assayed. 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. The urease activity of surface soils expressed as µg of NH4+ released g-1 soil h-1. The ranges of urease obtained in the present instigation from 5.9 to 16.0 with an average value of 8.74. Correlation between soil properties and soil urease were calculated and these results showed that urease activity was positively significantly correlated (r =0.943**) and available nitrogen (r = 0.510**), while no significant correlation was observed with clay, silt and pH.
