This International Standard 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 this International Standard provides the context for the presentation of results from analyses undertaken on soil samples. NOTE 1 It might not be possible or necessary to record data under all the headings listed in these descriptions. NOTE 2 Overall guidance for presentation of information from soil surveys is given in ISO 15903.
