Eleven soils collected from Champagne-Ardenne area (France) were used to investigate isoproturon sorption in laboratory conditions. Our results identified the organic matter (OM) and the ratio of calcite content to OM content (Rt) as the main two parameters governing isoproturon retention in soils. While organic matter favored pesticide sorption, calcite had an antagonistic effect since it limited isoproturon retention. The Rt ratio of calcite content to organic matter content in soils appeared to be a parameter that should be considered in predictive models in addition to OM in regions presenting calcareous soils. Adsorption of isoproturon as a function of Rt and OM was successfully described through a simple empirical model.
从香槟-阿登地区（法国）采集了 11 种土壤，用于在实验室条件下研究异丙隆的吸附。我们的研究结果表明，有机质（OM）和方解石含量与 OM 含量的比值（Rt）是控制土壤中异丙隆保留的两个主要参数。尽管有机质有利于农药的吸附，但方解石却产生了拮抗作用，因为它限制了异丙隆的保留。在存在石灰性土壤的地区，土壤中方解石含量与有机质含量的 Rt 比值似乎是除 OM 之外，预测模型中应考虑的一个参数。通过一个简单的经验模型，成功地描述了异丙隆的吸附与 Rt 和 OM 的关系。
