A field investigation was carried out in five tehsils of Jodhpur district of Rajasthan, India to study the variation in soil biological properties. Acid phosphatase, alkaline phosphatase, phytase, microbial biomass C (MBC), N ( MBN) and P(MBP) ranged between 1.10-3.45 µg PNP /g soil / h, 2.45 -8.42 µg PNP / g soil / h, 4.15-12.42 µg Pi / g soil / h, 27-52 mg / kg, 5.7-10.9 mg / kg and 1.10-4.10 mg / kg, respectively. Microbial population was higher in the rhizosphere soil compared to non-rhizosphere soil with maximum in Jodhpur (12.85%) followed by Bhopalgarh (11.24%) and Osian (10.70%). In general, phytase activity in soil was 1.4 and 2.75 times higher compared to acid and alkaline phosphatase activities. On an average, the rhizosphere soils contain 12%, 11% and 15% more biomass C, N and P compared to non-rhizosphere soil. Microbial population showed positive and significant correlation with nutrient availability and microbial properties.
