Management considerations
Deep sandy topsoil overlies a strong texture contrast between the surface soil and the subsoil. The A horizon exhibits a sporadically bleached soil leading to many fine segregations which are key features of this profile. The subsoil has prominent mottling which is another prominent feature of this soil type.

Increasing organic matter and maintaining vegetative cover is important to help stabilise the sandy topsoil and improve the soil structure. Penetration by deep-rooted crops is also a recommended management practice.
