They are often used in soil monitoring, sampling of contaminated sites and in modelling, and include: • upper and lower limits of a soil horizon, or of a functional set of horizons • depth increments (also called fixed depths), that are often used for sampling, e.g. 0-30cm, 30-60cm, and so on, • a single depth range in which a soil sample is taken and for which the analytical result is valid, and • soil slicing, that is, profile segmentation according to a specified vector, for instance, either regularly spaced intervals (1cm), or a user-defined vector of segment boundaries (i.e. 0-10, 10-25, 25-50, 50-100). Slicing is used in modelling to generate continuous depth functions for soil properties.

SOURCE ISO 11074 NOTE The subsoil can be: (i) a grouping of one to several horizons underlying the horizons with recent humus accumulation from humifying biomass or (ii) a domain of a soil with a specific vertical extension starting well below the soil surface (e.g. 15-75 cm).

NOTE 1 For arable lands, topsoil refers to the ploughed soil depth; for grasslands, it is the soil layer with high root content. NOTE 2 The topsoil can be: (i) a grouping of one to several A horizons or (ii) a domain of a soil with a specific vertical extension starting from the surface (e.g. 0-15 cm). NOTE 3 In most soil description guidelines, the topsoil is composed of all A horizons occurring in a soil profile.
