Horizon	Depth (cm)	Description
A1	0–10	Brown (7.5YR4/3); sandy loam; massive (structureless); very weak dry consistence; very few fine subrounded quartz gravels; very few fine ferromanganiferous nodules; common fine to very fine roots; pH 5.2; clear and smooth boundary to:
A2	10–30	Yellowish brown (10YR5/4), conspicuously bleached very pale brown (10YR8/2 dry); sandy loam; massive (structureless); weak dry consistence; a few fine to very fine subrounded quartz gravels; few medium ferromanganiferous nodules; a few fine to very fine roots; pH 5.4; abrupt and irregular boundary to:
B21	30–50	Yellowish brown (10YR5/4) with common medium distinct yellowish red (5YR4/6) mottles; medium heavy clay; strong fine prismatic, parting to moderate fine subangular blocky structure; smooth ped-fabric; strong moderately moist consistence; common fine to very fine roots; pH 8.2; clear and tongued boundary to:
B22	50–80	Strong brown (7.5YR5/6); medium heavy clay; moderate fine to very fine prismatic, parting to weak fine to very fine subangular blocky structure; rough ped-fabric; strong moderately moist consistence; few fine to medium manganiferous nodules; few faint slickensides; few fine to very fine roots; pH 8.7; gradual and smooth boundary to:
B23	80–110+	Reddish yellow (7.5YR6/8) with many medium distinct yellowish red (5YR4/6) mottles; medium heavy clay; massive (structureless); strong moderately moist consistence; few fine to medium manganiferous nodules; pH 8.5.
B23	80–110+
Management Considerations
Strong texture contrast profile, highly sodic subsoil. Subsurface horizon is leached (bleached). Fewer nutrients available. Highly acidic surface and subsurface soil and alkaline subsoil. Note high fine sand content throughout. Less clay with deeper subsoil (undetected by hand texture) and higher proportion of magnesium to calcium at depth. Subsoil is very highly dispersive. Limited (preferably no) exposure required to remain stable. Slightly higher salinity with depth. Surface soil is only slightly dispersive. Landscape position, gentle crest. Water shedding.
