ISO 18311:2016规定了一种技术，用于在当前环境条件下确定人为影响（例如物质）对田间土壤生物摄食活动的影响。此外，还介绍了使用该方法监测土壤生物质量的方法（见附录A）。土壤无脊椎动物和微生物分解有机质是一个关键的过程，它决定了重要的土壤功能，如植物的养分有效性和土壤肥力的维持。此外，分解的植物凋落物为多种生物提供栖息地和食物，从而支持生物多样性和生态系统服务[33][34]。 ISO 18311:2016适用于土壤生物活跃的所有土壤。 诱饵薄层试验的使用与是否有凋落物层无关。ISO 23611-6（另见参考文献[20]）规定了现场研究的抽样设计。根据研究目的以及待调查场地的条件（例如土壤性质、污染等），设计可能会有所不同。 ISO 18311:2016不适用于半陆地或极浅土壤。在极端的气候或地理条件下（例如在高山上），很难使用它。

ISO 18311:2016 specifies a technique for determining the effects of anthropogenic impacts (e.g. substances) in the context of the prevailing environmental conditions on the feeding activity of soil organisms in the field. In addition, the use of this method for monitoring the biological quality of soil is described (see Annex A). The breakdown of organic matter by soil invertebrates and microorganisms is a crucial process that determines important soil functions such as nutrient availability for plants and the maintenance of soil fertility. In addition, decomposing plant litter provides habitats and food for a wide range of organisms, thus supporting biodiversity and ecosystem services [33][34]. ISO 18311:2016 is applicable to all soils in which soil organisms are active. The use of the bait-lamina test is independent from whether there is a litter layer or not. The sampling design of field studies in general is specified in ISO 23611？6 (see also Reference [20]). The design can vary according to the aim of the study as well as conditions (e.g. soil properties, contamination, etc.) of the site to be investigated. ISO 18311:2016 is not applicable for semi-terrestrial or very shallow soils. It can be difficult to use it under extreme climatic or geographical conditions (e.g. in high mountains).
