Horizon	Depth (cm)	Description
A11	0–15	Dark greyish brown (7.5YR3/1); sandy loam; massive (structureless); weak consistence when dry; pH 5.0; gradual smooth boundary to:		Melacic-Basic, Arenic, Bleached-Orthic TENOSOL
A12	15–60	Dark greyish brown (7.5YR3/1); loamy sand; massive (structureless); firm consistence when moderately moist; very few fine soft segregations; pH 5.0; distinct smooth boundary to:
A13	60–120	Dark greyish brown (7.5YR3/1) with common medium greyish brown mechanical mixing from other horizons; loamy sand; massive (structureless); very weak consistence when moderately moist; pH 5.7; gradual smooth boundary to:
A2	120–140+	Light brownish grey (2.5Y6/2); conspicuously bleached (10YR7/2 dry); sand; massive (structureless); very weak consistence when moderately moist; pH 6.0.
Management Considerations:
Soil is sandy and deep throughout with minimal pedological development. Sandy soils with high permeability and water drainage capacity. Relatively low clay percentage and low inherent fertility. Deep sandy soil (90% sand for all horizons). Strongly acidic becoming moderately acidic with depth.
