Abstract :

 Soil fertility can be related to the phosphatase activity of soil. Thus the soil health of the tea gardens of  Diugarh District was determined by the phosphatase activity of the soil. The acid phosphatase activity was found at the range of 273.29 ± 4.67 – 451.62 ± 11.72 units/g of soil and the alkaline phosphatase activity was  found at the range of 295.79 ± 3.86 – 539.88 ± 20.92 units/g of soil.  Rhizospheric soil from the shade trees was further screened and microbes with phosphate solubilising capacity were  isolated on Pikovskaya agar medium. Seventeen microbes were obtained with phosphate solubilising capacity. On the  basis of solubilisation zone and efficacy of viability during enrichment culture four active isolates were selected for  study. From the active isolates obtained the phosphatase activities were determined. The acid phosphatase specific  activity was obtained at a range of 9,397.56 ± 61.33 – 10,021.22 ± 91.78 and the alkaline phosphatase specific activity  was obtained at a range of 10,411.67 ± 73.47 – 13,854.33 ± 64.02.
