Horizon	Depth (cm)	Description
Ap	0–15	Very dark greyish brown (10YR3/2); sandy clay loam; moderate medium to coarse polyhedral structure; rough ped fabric; very weak consistence when dry; moderately calcareous; many very fine roots; pH 8.5; smooth and clear boundary to:
B1	15–40	Dark grey (2.5Y4/1); light clay; weak coarse to very coarse platy, parting to very coarse and coarse angular blocky structure; rough ped fabric; firm consistence when dry; very fine to fine roots common; pH 8.5; wavy and clear boundary to:
B21	40–75	Very dark grey (2.5Y3/1); medium clay; strong coarse to very coarse prismatic, parting to medium to fine subangular blocky structure; smooth ped fabric; strong consistence when dry; very fine to fine roots common; pH 8.5; wavy and gradual boundary to:
B22	75–100	Dark grey (2.5Y4/1) with a few medium faint grey mottles; medium clay; strong coarse to medium prismatic structure; rough ped fabric; very strong consistence when dry; few fine calcareous nodules (<2 mm); few fine to very fine roots; slightly calcareous; pH 8.5; wavy and gradual boundary to:
B23	100–135+	Light yellowish brown (2.5Y6/4) with a few distinct large dark grey (2.5Y4/1) biological mixing; medium clay; moderate coarse polyhedral structure; rough ped fabric; strong consistence when moderately moist; few fine calcareous nodules, tubules and very coarse laminae; few very fine roots; very highly calcareous; pH 9.0.
Management Considerations
Moderate susceptibility to wind erosion where vegetation coverage inadequate Moderately to strongly alkaline pH trend Imperfect to poorly drained subsoils with grey & yellow mottling Low landscape position Lower subsoil has increased dispersibility Moisture status of the profile variable with depth Moderate to strongly structured throughout Effective rooting depth to 135 cm (observed)
