摘要: Abstract The effects of charcoal amendment on adsorption, leaching and degradation the herbicide isoproturon in soils were studied under laboratory conditions. adsorption data all fitted well with Freundlich empirical equation. It was found that increased rate amended (correlation coefficient r = 0.957 ⁎⁎ , P DT 50 ) greatly extended when added inceased from 0 to 50 g kg − 1 (for Paddy soil, values 54.6 71.4 days; for Alfisol, 16.0 136 days; Vertisol, 15.2 107 days). significantly negatively correlated amount charcoal. This research suggests may be an effective management practice reducing pesticide enhancing its persistence soils.
