B21 | 40-60 cm | Pale brown (10YR6/3) with strong brown (7.5YR5/6) and dark red (2/5YR4/8) mottles; medium clay; strong coarse blocky structure; pH 5.6. |
The surface (A1) horizon is very strongly acid. The subsurface (A2) horizons are strongly acid, becoming moderately acid. The upper subsoil is moderately acid. | The upper soil profile is non-sodic throughout. | ||
Soluble salt levels are very low throughout the profile. | The clay percentage increases significantly at the A/B horizon interface. |
