depth interval
Definition:
Fixed depth range where soil is described and/or samples are taken.
Description:
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.
