NF EN ISO 23611-5, X31-224-5 (08/2024)

ISO 23611-5:2011 specifies a method for the sampling, extraction and conservation of macroinvertebrates from the soil, including the litter area. The proposed method is a prerequisite for the use of these animals as bioindicators (for example to assess the quality of soil as a habitat for organisms). The main principles of this method consist of having a rapid assessment (carrying out the sampling of an area in one or two days with basic equipment and with a reduced number of field assistants), to be able to deal with all the taxonomic groups of soil macroinvertebrates at the same time and in the same place. The TSBF (tropical soil biology and fertility) method has evolved and some modifications have been introduced in order to use it in temperate regions. The sampling and extraction methods of ISO 23611-5:2011 are applicable to almost all soils. Exceptions may be soils under extreme climatic conditions (hard, frozen or flooded soils) and matrices other than soil, for example tree trunks, plants or lichens. The sampling plan is specified in ISO 23611-6.
