The effects of two farm manures, bovine manure (BM) and chicken manure (CM), on imazaquin degradation in a sandy loam soil were studied under laboratory conditions. The degradation of imazaquin in BM and CM-amended soil (10% by w/w) was about 2.4 and 1.5 times, respectively, faster than that in unamended soil. Different amendment ratios of BM to soil lead to different degradation rates of imazaquin. However, higher mix ratio did not necessarily increase the degradation, and the optimal active degradation of imazaquin was observed at the approximate mix ratio of 10:1 of soil to BM. Imazaquin de...
