This standard sets out the essential conditions for the use of white earthworms as biological indicators (e.g. a tool to assess soil quality as a habitat for soil organisms), i.e. collection and processing of soil samples for collection of white earthworms, and extraction of white earthworms from soil samples. It specifically deals with the method of extracting white earthworms. References include basic ecological information about white earthworms and the use of white earthworms as biological indicators to evaluate the soil environment. This standard covers all soil habitats where white earthworms appear. Apply to. In general, soil sample collection for field research is described in KS I ISO 10381-1. These details may vary depending on the climatic and regional circumstances of the collection site. An overview of how pollutants affect whitening earthworms depending on packaging conditions is provided in reference [6]. The classification method for other soil biota such as earthworms and microarthropods is KS I ISO 23611-1. and KS I ISO23611-2. This standard is not appropriate for semi-terrestrial organisms living in or near water and may be difficult to use under extreme climatic or geographical conditions such as alpine areas. Soil invertebrates When collecting, it is strongly recommended to describe the characteristics of the collection location (taking into account climate, agricultural land use, etc.). However, describing the characteristics of the collection site is not covered by this standard.
