侵蚀后的化学土壤退化是土壤退化的第二种最丰富的形式，因此对我们有限的土壤资源构成威胁，因为它往往使其变得不那么有用。因此，有必要了解土壤化学降解的方式。本综述文件旨在强调土壤化学退化的一些原因。土壤化学降解的一种方式是通过土壤污染;通过扩散污染或局部污染源。诸如土壤盐碱化、酸化、化肥施用和农药使用等驱动因素都有助于土壤化学退化的进程。该审查文件阐明了这些退化驱动因素，并讨论了为确定土壤化学退化而开发的一些评估方法。在评估化学品退化时，可将评估工具和土壤质量指标参数结合起来使用，也可使用单一的评估工具。其中一些工具包括生态毒理学方法，土壤质量测试。两种或两种以上评估工具的组合有助于土壤的恢复过程。化学退化的土壤在大多数情况下可能是不可逆转的，因此，防止化学退化将有助于农业的可持续性。
Chemical soil degradation after erosion is the second most abundant form of soil degradation and as such poses a threat to our finite soil resource, as it tends to render it less usable. It is therefore necessary to understand the means by which soils are degraded chemically. This review paper seeks to highlight some of the causes of soil chemical degradation. One way by which soils degrade chemically is through soil contamination; either by diffuse contamination or from localised sources. Drivers such as salinization, acidification of soils, chemical fertilizer application and use of pesticides all tend to aid the process of soil chemical degradation. The review paper sheds light on these drivers of degradation and also discusses some assessment methods developed to determine soil chemical degradation. In assessing chemical degradation, a combination of assessment tools and soil quality indicator parameters or single assessment tools may be employed. Some of these tools include ecotoxicological approach, soil quality test. A combination of two or more assessment tools aids in the process of restoration of the soil. Chemically degraded soils may be irreversible in most cases and as such its prevention will aid in agricultural sustainability.
