Effect of Copper Contamination on Soil Biochemical Activity and Performance of Rice (Oryza sativa L.)
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 5
Abstract
A pot culture experiment was carried out to determine the effect of soil contamination with CuSO4 5H2O in different concentrations on the activity of soil enzymes (Dehydrogenases, Urease, Acid and Alkaline Phosphatase) and dry matter yield of rice. The experiment was conducted in completely randomized design comprising 6 levels of Cu (0, 50, 100, 150, 200 and 250 mg kg-1 soil). Soil contamination with Cu also had a negative effect on the dry matter yield and yield attributes of rice. Toxic activity of Cu on rice appeared at the lowest dose (100 mg kg-1), and higher doses of Cu were found to intensify the effect. The enzyme activity in the soil samples was determined at 30, 60, 90 DAS and at harvest. The enzyme activity increased up to 30 DAS which later decreased to harvest. The results indicated that, soil contamination with CuSO4 5H2O of 100, 150, 200 and 250 mg Cu kg-1 soil significantly inhibited the activity of dehydrogenases, urease, acid and alkaline phosphatases. The soil enzymes can be arranged in terms of their sensitivity to Cu as follows: dehydrogenases > urease > alkaline phosphatase > acid phosphatase. Dehydrogenases and urease appeared to be better indicators of soil contamination with Cu, as their activity was more strongly inhibited by Cu than the activity of phosphatases.
