Abstract
Spatial variability of topsoil depth is of interest to many agricultural practitioners since it relates to the ability of soil profile to accumulate water and nutrients. Conventional on-the-go mapping of apparent soil electrical conductivity provides valuable information related to the spatial variability of soils, but does not always allow detecting differences that occur with depth.
