B22	120 – 150 cm	Light brownish grey (10YR6/2) with very few fine distinct yellowish brown mottles; medium heavy clay; strong prismatic to lenticular structure (less than 200 mm), parting to strong coarse angular blocky structure; strong consistence moist.

• Lack of strong texture contrast between surface (A) horizons and subsoil (B) horizons.
• Conspicuously bleached A2 horizon.

The soil profile is very strongly to strongly acid throughout.	The soil profile has a very low salinity rating throughout.	The subsoil is sodic.
The levels of exchangeable aluminium are high throughout.the strongly acid profile.	The clay content increases gradually with depth down the soil profile.

Management Considerations:

• Bleached subsurface (A2) horizon indicates that seasonal waterlogging occurs above the more impermeable clay subsoil. This horizon will become ‘spewy’ when saturated.
• The dense and coarsely structured upper subsoil is sodic and disperses in water. This is likely to restrict root and water movement in the subsoil. Water is likely to build up on top of this horizon after heavy rains and waterlogging will occur.
• The subsoil has a very low exchangeable calcium:magnesium ratio (<0.1). Calcium deficiency could occur as a result.
• Availability of some nutrients may be low in the very strongly to strongly acid soil profile. This could apply to trace elements such as copper and molybdenum.
