Horizon	Depth (cm)	Description
A1	0–10	Dark greyish brown (10YR4/2); organic sandy loam; weak medium subangular blocky structure; firm consistence (dry); pH 6.7:
B21	10–30	Greyish brown (10YR5/2) with common faint brownish yellow mottles; medium clay; strong fine polyhedral structure; strong consistence (dry); pH 7.2:
B22	30–50	Brownish yellow (10YR6/6) with a few distinct orange mottles; medium heavy clay; strong medium and coarse polyhedral structure; pH 8.7:
C	50–100+	Pale mottled sandy material.
Management Considerations
Strong textural contrast Shallow topsoil depth, susceptible to sheet and rill erosion Sodic topsoil (crusting of surface) and subsoil which is also dispersive Variable clay depth and depth to clay, gilgai characteristics Swale, very poor site drainage
