Horizon	Depth (cm)
A1	0–8	Dark brown to brown (7.5YR4/3); loamy sand, heavy; weak fine subangular blocky structure; rough ped-fabric; weak consistence (dry); field pH 7.0; abrupt boundary to:
A21	8–25	Brown (10YR4/4), light brown (10YR6/4 dry); fine sandy loam; massive (structureless); earthy ped-fabric; weak consistence when dry; many fine subangular quartz gravels; field pH 7.0; gradual boundary to:
A22	25–35	Yellowish brown (10YR5/4), conspicuously bleached very pale brown (10YR7/3 dry); coarse sandy loamy; massive (structureless); earthy ped-fabric; weak consistence when dry; many fine and medium subangular quartz gravels; field pH 7.0; sharp boundary to:
B21	35–60	Yellowish red (5YR4/6) with a few fine faint yellow mottles; light clay, silty; strong medium prismatic, parting to fine angular blocky structure; smooth ped-fabric; strong consistence when dry; field pH 4.7; gradual boundary to:
B22	60–80	Yellow brown(10YR5/4) with common distinct medium dark red (2.5YR3/6) and fine brownish yellow (10YR6/8) mottles; light clay; silty; moderate medium polyhedral, parting to fine subangular blocky structure; smooth ped-fabric; firm consistence (slightly moist); field pH 5.5; clear boundary to:
B23	80–105	Brown (7.5YR4/3) with a few fine faint red and grey mottles; light clay, silty; strong medium prismatic, parting to medium and fine angular blocky structure; smooth ped-fabric; very firm consistence when slightly moist; field pH 6.5; gradual boundary to:
B24	105–130+	Light yellowish brown (10YR6/4), with common distinct medium reddish brown (7.5YR6/6) mottles; light clay; weak coarse polyhedral parting to moderate fine subangular blocky structure; rough ped-fabric; weak consistence (slightly moist); field pH 7.0.
Management Considerations:
Texture contrast soil. Occasionally Gradational texture change with depth. Light textures, well drained to subsoil. Neutral surface (A1-A22); highly acidic upper subsoil (B21) grading towards neutral with depth. Surface soil has protective organic matter content, still slightly susceptible to sheet and rill erosion. Subsurface horizons bleached, susceptible to sheet and rill erosion. Subsoil likely to be sodic and dispersive at depth. Imperfectly too poorly drained.
