B22s
35/45-80 Olive yellow (2.5Y6/8 moist) with light red (2.5YR7/6 dry) mottles; fine sandy clay loam; apedal massive structure; strong consistence; pH 5.1; gradual and smooth boundary to:

B23g
80 +Grey (2.5Y5/1) with (10-15%), yellowish brown (10YR5/8 moist) mottles common; medium clay; medium (20-50 mm) prismatic, parting to coarse (20-50 mm) and medium (10-20 mm) blocky structure; firm to very firm consistence; pH 4.9.

Management considerations
Better drained surface than the majority of valley floor soils in this landform and so less prone to pugging by grazing animals. Subsoil subject to waterlogging. Acidic profile responding to lime. Compare this profile to SW55 for a variation in this type of soil.
