This sandy soil is also acidic meaning that the nutrient holding and waterholding capacity of the soil would be considered low. However the organic matter levels in the surface (6.5% OM) provides increased capacity for nutrient and water storage. The low pH means that nutrient availability is low and that aluminium and iron become more available/prevalent. The high clay content by laboratory determination of the surface soil is not consistent with the field texture and may indicate sample contamination. The light textures of this soil do not allow for the measurement of fine particle (silt and clay) stability (Emerson test). Where exposed this material is easily moved (little cohesion).
For management the depth of free draining material is important as is the variability of topsoil/soil depth. This soil varies in surface soil depth and is restricted at 85cm by a “coffee rock” horizon, restricting some downward drainage, promoting some lateral flow.
