Horizon	Depth (cm)	Description
A1	0–5/10	Very dark grey (10YR3/1) with a few faint orange organic stain mottles; light medium clay; moderate medium subangular blocky, parting to fine subangular blocky structure; rough ped-fabric; very strong dry consistence; pH 6.0; clear and discontinuous boundary to:
A2	5–15	Grey (10YR5/2), bleached light grey (10YR7/2d), with a few medium faint brown mottles; fine sandy clay loam; massive (structureless); very few medium ferruginous concretions; many fine macropores; pH 7.2; abrupt and discontinuous boundary to:
B21	10/15–40	Dark grey (2.5Y4/1), with a few medium faint orange mottles; heavy clay; strong medium to fine prismatic, parting to fine angular blocky structure; smooth ped-fabric; very strong dry consistence; few distinct slickenside cutans; pH 8.5; gradual and wavy boundary to:
B22	40–80	Dark greyish brown (2.5Y4/2) with very few fine faint orange/brown mottles; heavy clay; strong medium prismatic, parting to fine and very fine angular blocky structure; smooth ped-fabric; very strong dry consistence; common distinct slickenside cutans; pH 8.5; distinct and wavy boundary to:
B23	80–110	Olive grey (5Y5/2) with very few fine faint orange/brown mottles; heavy clay; strong medium angular blocky structure; smooth ped-fabric; very firm moist consistence; common coarse ferromanganiferous nodules with few coarse calcareous soft segregation's; common distinct slickenside cutans; pH 8.8; distinct and wavy boundary to:
B24	110–180+	Pale olive (2.5Y5/2) with a few very coarse prominent (5YR4/6) mottles; medium heavy clay; strong very coarse lenticular, parting to moderate coarse and medium angular blocky structure; smooth ped-fabric; few fine manganiferous nodules with very few medium calcareous nodules; many prominent slickenside cutans; pH 8.7.
Management Considerations
Cracking clay profile Discontinuous bleached subsurface horizon provides extra depth to top of subsoil but compaction prone Alkaline subsoil; upper subsoil non-sodic, sodic at depth. Sets(consistence) very hard when exposed and dried Rooting depth dependent on major cracks for drainage and air (gaseous) movement Strong structure in upper subsoil Landscape position, drainage accumulation area
