Management considerations
Strong texture contrast between the surface soil and the subsoil is a very important soil feature and can impact upon the permeability aspects of the profile. The surface soil is sandy, while the subsoil is sodic, mottled medium clay containing many fine and coarse segregations. Increasing the organic matter of the soil will help to retain nutrients in the loose, sandy topsoil, while the application of gypsum should improve soil structure and drainage properties down the profile.
