Bibliography

ISO 25177:2008 is a guide for describing the soil and its environmental context at a given site. Sites can be natural, near-natural, urban or industrial. It is important to realize that a number of soil samples can be taken at a site to support the soil description. The information provided by the descriptions in ISO 25177:2008 provides the context for the presentation of results from analyses undertaken on soil samples.
