Soil Profile

A vertical section of a turf surface and rootzone. It will typically show more than one soil horizon, especially the surface organic layer, known as thatch, as well as topsoil or main rooting medium, and may be sub-soil where present. A good depth for analysing a soil profile will be from 150mm to 300mm, but this will depend upon the circumstances and requirements of the soil profile. A soil profile will often be able to provide an indication of soil structure, root growth and soil fauna activity.
