Description

0–5

Dark grey (10YR4/1); sand; single grain (structureless); loose to very weak consistence when dry; field pH 6.0; gradual boundary to:

A21

5–25

Light brownish grey (10YR6/2); bleached (10YR8/1 dry); sand; single grain (structureless); loose to very weak consistence when dry; field pH 5.5; gradual boundary to:

A22

25–80

Light grey (10YR7/2); bleached (10YR8/1 dry); sand; single grain (structureless); loose consistence when dry; field pH 6.5; clear boundary to:

Bhs

80–110

Dark yellowish brown (10YR4/4); sand; massive (structureless); weak consistence when dry; field pH 6.5: clear boundary to:

B21

110–140

Pale yellow (10YR 6/4); sand; single grain (structureless); loose to very weak consistence; field pH 6.5; abrupt boundary to:

D/C

140–150+

Light yellowish brown (10YR6/4) with many pale brown (10YR6/3), and brown (7.5YR4/4) coarse prominent mottles; heavy coarse sandy clay loam; massive (structureless); very firm dry consistence; field pH 5.5.

Management Considerations

Deep, sandy soil, slightly acid, becoming acid at depth (clay).
Leached soil, very little nutrient available, apart from thin surface soil.
Clayey subsoil at depth, possible deep Sodosol.
Surface soil maintaining stability while vegetation cover exists, susceptible to sheet rill and wind erosion.
Subsurface soil has loose to weak consistence (no binding).
Dune; site drainage varying from moderately well drained to well drained; receiving and distributing moisture.
