This International Standard 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]. This International Standard 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. This International Standard 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).
