Soil samples

A soil sample is a sample of the soil that is taken for further analysis in the field or in a laboratory. A sample is always taken at a certain depth (from/to). Optionally, a certain technique can be described (e.g. disturbed or undisturbed), as well as the conditions of sampling (e.g. atmospheric conditions, etc.). The results of analyses carried out on the sample shall be kept as observations linked to the sample. A sample can be linked to one or more commands and attachments can also be linked to a sample (e.g. analysis results or reports). A soil sample is either a single sample or a mixed sample (this is the type). A single sample is always linked to one soil location or one depth interval. A soil location or depth interval may have 0 or more single samples. A mixing sample can be linked to one soil site, one soil site or one soil depth interval. These may have 0 or more mixing samples.
