Surface soil
A1	0 – 5 cm	Dark greyish brown (10YR4/2); silty loam; weak crumb structure; firm consistence dry; few medium ferruginous concretions; gradual change to:
A21	5 – 50 cm	Greyish brown (10YR5/2); silty loam; massive; very firm consistence dry; few medium ferruginous concretions; pH 6.1; clear wavy change to:
A22	50 – 60 cm	Greyish brown (10YR5/2); silty loam; massive; strong consistence dry; many medium ferruginous concretions; clear wavy change to:
Subsoil
B2	60 – 100+ cm	Grey (10YR5/1) finely mottled with brownish yellow (10YR6/6); heavy clay; strong coarse prismatic structure, very strong consistence dry; very many (>50%) medium to coarse ferruginous concretions and many rounded basalt stones; pH 6.7.

• Strong texture contrast between surface (A) horizon and subsurface (B2) horizon.

• The profile is slightly acid throughout
• Plant roots would find it difficult to penetrate the massive subsurface (A21 and A22) horizons which would be hard setting when dry
• Plant available water capacity is considered to be low; estimated at 57 mm.

• The nutrient holding capacity of the soil is low (based on the sum of the exchangeable basic cations and the depth of roots observed)
• Potassium levels are very low and a response to potassium would be expected.
