Bottom depth intervals

An in-depth interval is linked to one or more soil building. A soil structure must have one or more in-depth intervals. An in-depth interval describes a part of the subsoil of the coupled soil site. The latter contains the location of the profile well or bore (X, Y, possibly supplemented by Z of the ground level), where the depth intervals describe the soil at that location in depth. An in-depth interval is a horizon or a layer (this is the type). A horizon is a visually distinct part of the soil created by converting the parent material through pedogenetic processes or by depositing organic matter. A horizon has homogeneous morphological and analytical characteristics for most soil variables. A layer, on the other hand, is not created by pedogenetic processes. This type is used less frequently, but for example in archaeological contexts or in steel collection layers in soil monitoring. Each depth interval has at least one upper and lower boundary indicating the depth of the horizon or low. If the limit is less clear or is not horizontal, two upper or lower limits can also be specified. It is possible that multiple in-depth intervals of the same soil site overlap in depth in whole or in part. In exceptional cases, the input of historical data is possible to create in-depth intervals without upper or lower limits.
