Soil microbial enzyme activities in different age series sponge iron solid waste dumps with respect to reclamation

Soil enzymes are primarily derived from over all microbial population and activities of microorganism. Study of soil enzymatic activities provide an insight in to the microbial biotransformation process and soil enzymes could be used as the potential biochemical indicators of soil quality. In the present investigation soil microbial enzymatic activities of dehydrogrogenase, amylase, invertase, urease, protease and phosphtase were measured in different age series i.e. 0, 1, 3 and 5 years old sponge iron solid waste dumps to determine probable biotransformation of the waste. The study indicated that the soil microbial enzymatic activities were not detected in fresh dump (0 year old). But, there was an increasing trend in soil microbial enzymatic activities from 1 year to 5 year old waste dumps. The comparative analysis of the soil microbial enzymatic activities in different age series sponge iron solid waste dumps reflects the gradual improvement of the functionality in the older dumps.
