Abstract	Soil health can be defined as the ability of a specific kind of soil to provide a natural or artificial ecosystem, which helps to maintain balanced plant and animal life. Soil organisms act as the primary agents of nutrient cycling and regulate the dynamics of soil organic matter. Activities of soil enzymes have great potential to assess the health of soil biota, as soil enzymes control mineralization and therefore influence availability of N, C and P. Soil enzymes provide an easy, relatively rapid and low cost procedures to monitor soil health as they are considered to be indicators for measuring the degree of soil degradation. The present investigation was aimed at evaluating the basal soil respiration, total microbial activity and potential enzymatic activities of -glucosidase, urease, phosphatase and dehydrogenase in gold mine tailings and was compared with fertile soil types like vermicompost, garden soil and control soil from mine area. Differences in the respective analyses reflect the changes in the N, C and P metabolism in the soil, which is the result of total microbial activity. Amending the mine tailings with vermicompost showed significant effect in restoring the soil quality, which is reflected as increased enzyme activity, with different levels of amendment on increasing time interval. _____________________________________________________________________________________________________________
