Abstract

The dumping of waste poses various detrimental effects on the soil quality i.e., mostly soil microbial and biochemical properties. In the present study the soil protease activity was evaluated in various sites of Balasore District such as Balasore Sadar, Soro NAC, Nilagiri NAC and Jaleswar NAC. For each dumping site there was a control site. The maximum protease activity found in Balasore Sadar was 6.78±0.05 μg tyrosine g-1 of soil hr-1 and minimum was 3.62±0.14 μg tyrosine g-1 of soil hr-1. In Soro NAC the highest protease activity was 6.62±0.74 μg tyrosine g-1 of soil hr-1 whereas lowest was 2.98±0.14 μg tyrosine g-1 of soil hr-1. Similarly in case of Nilagiri NAC the major protease activity was recorded to be 6.71±0.15 μg tyrosine g-1 of soil hr-1 however lower protease activity was found 4.02±0.013 μg tyrosine g-1 of soil hr-1. It was found in that Jaleswar NAC that the protease activity was maximum in dumping site (6.75±0.034 μg tyrosine g-1 of soil hr-1) and minimum in control site (3.68±0.019 μg tyrosine g-1 of soil hr-1). The present experiment showed that dumping of waste on open land field increases the soil protease activity as compared to their control site soil.
