Description
A1
0–10
Dark reddish brown (5YR3/3) sandy loam; weak medium blocky structure; very weak consistence (dry); contains many (25%) sandstone fragments (7 mm average diameter); pH 5.7; abrupt boundary to:
A2
10–25
Reddish brown (5YR4/4) fine sandy clay loam; weak medium blocky, parting to moderate fine polyhedral structure; weak consistence (dry); contains many (25%) fine sandstone fragments (10 mm average diameter); pH 6.2; clear boundary to:
B1
25–60
Yellowish red (5YR4/6) medium clay; moderate medium polyhedral parting to strong fine polyhedral structure; firm consistence (dry); contains very few (<2%) soft and hard manganiferous segregations (6–8 mm diameter); and many (50%) fine sandstone gravels (up to 100 mm diameter); pH 5.9; gradual boundary to:
BC
60+Mainly sandstone (90%); contains (10%) yellowish red (5YR5/8) medium clay; contains very few (<2%) soft and hard manganiferous segregations (6–8 mm diameter); and very many (90%) fine sandstone gravels.
Management considerations
  • Strong texture contrast between surface (A) horizon and the upper subsoil (B21) horizon
  • Shallow soil profile
  • Acidic profile
  • Rock outcrop
