Influence of 3 Kinds of Organic Fertilizers on the Degradation of p, p′-DDT in Clay under Flooding Conditions

Abstract:

Using pot experiment to study the influence of three organic fertilizers of chicken manure compost (CM), activated sludge (AS) and cassava residue compost (CR) on the degradation of p, p'-DDT in clay soil under flooding conditions. The results showed that the two kinds of organic fertilizers of AS and CM could effectively accelerate the degradation of p, p'-DDT in clay soils, and the degradation effect was the best when adding 2% CM or 3% AS in clay soil. However, the influence of CR on the degradation of p, p'-DDT was not obvious. The degradation rates of P, P′-DDT in the treatment on adding 1% AS were from zero to 7.4% higher than that of 1% CM. The degradation rates of P, P′-DDT in the treatment on adding 2% AS were from zero to 11.3% higher than that of 2% CM. The degradation rates of P, P′-DDT in the treatment on adding 3% AS were from 8.3% to 27.4% higher than that of 3% CM. which indicated that AS is more conducive to the degradation of p, p'-DDT in the clay.
