Management considerations
This strongly texture contrast soil has a hard setting surface soil with conspicuously bleached A2 horizon. Sodic, mottled and alkaline subsoils are features of this soil type. The application of gypsum counters sodicity and may reduce dispersion, while increasing organic matter and vegetative cover is important to add nutrients to the profile.
