Impacts of compost and wastewater sludge on soil biologic activities

Abstract

The use of agrochemical such as chemical fertilizers and pesticides has caused tremendous harm to the eco-environment. Organic matter (OM) addition to soil often leads to a rapid increase in the activities of various enzymes and reactivation of biogeochemical cycles in soil. One of the major concerns today in all over the world is the pollution and contamination of the soil. In fact hydrolytic enzymes are sensitive indicators of management induced changes in soil properties due to their strong relationship with soil organic matter (OM) content and quality. An experiment was conducted to study the impacts of combined fertilizer on soil properties in comparison with adding organic as solid waste compost (SWC) of plant origin or municipal wastewater sludge (MWWS) to sandy loam brown forest soil
