Description

Ap

0–20

Dumped material.

A

20–40

Light yellowish brown (2.5Y6/4); sand; minor organic matter content; weak consistence when dry; pH 5.6.

B21

40–120

Brownish yellow (10YR6/8); sand; very weak consistence; pH 5.6.

B22

120–170+

Yellow (10YR7/8); sand; very thin irregular silcrete laminations; very weak consistence; pH 5.6.

Management Considerations

  • Deep sand profile
  • Acidic hydrophobic topsoil, susceptible to wind and minor sheet erosion
  • Topsoil, low nutrient capacity
  • Acidic subsoil, low nutrient capacity
  • Landform element is a Duneslope, well drained site drainage
