POTENTIAL OF COW DUNG AMENDMENT TO ENHANCE LINDANE BIODEGRADATION IN CONTAMINATED AGRICULTURAL SOIL

Efficacy of cow dung (CD) amendment as potential bioremediation tool for cleanup lindane contaminated agricultural soil was investigated in microcosms simulated the laboratory. Microcosm CDS with 5 mg kg-1 fortified 200 g CD while CTS1 similar to except that it received no amendment. Setup CTS2 contained uncontaminated only and designed evaluate physico-chemical biological dynamics under unstressed conditions. The trends observed physico-chemistry were much more pronounced setups when compared CTS2. This relatively significant between days 15 which incidentally periods striking microbial population changes, whereas, remained stable. In spite initial drop at onset study (though less than CTS1), over 18% degradation occurred system against 9% CTS1. Although overall rates both soils presented statistical differences (P < 0.05), effected a higher level degradation. Data this investigation suggest is stimulant relevant organisms metabolic functions test especially early stages study. Therefore, utilization organic wastes great should be exploited. will help reduce amount waste destined landfill, thus reducing landfill gas emissions. It also provide cheaper source supplement purposes ultimate aim cost bioremediation.
