We compared the soil sorption coefficient ( ) measured by batch and centrifugation methods using a Japanese andosol and ten pesticides. Although the values measured by both methods increased with time, those obtained the batch method tended to be higher during the test period. The difference in values between the two methods affected pesticide concentrations estimated in the soil solution, and the results estimated using values obtained the batch method underestimated the observed trends.
我们使用一种日本火山灰土壤和十种农药,比较了通过批量法和离心法测得的土壤吸附系数( )。尽管两种方法测得的 值均随时间增加,但在测试期间,通过批量法获得的值往往更高。两种方法测得的 值差异影响了土壤溶液中估计的农药浓度,并且使用批量法获得的 值估计的结果低估了观测趋势。
