Management Considerations:

Strong texture contrast between the surface soil and the subsoil is a very important soil feature and may impact upon subsoil permeability. The soil type also exhibits slightly acidic topsoils, with a fragipan forming a distinct boundary to the heavier textured and more alkaline subsoil. Calcium carbonate nodules are associated with alkaline soils and found in the subsoil also.

The application of gypsum to improve soil structure and permeability is recommended while penetration of the subsoil by deep-rooted crops is also useful. Minimum tillage practices will help to avoid bringing the sodic, dispersive material to the surface.
