Subsoil
B21	30-60 cm	Reddish brown (5YR4/4), with many greyish brown (10YR5/2) mottles; clay; weak medium angular blocky structure; pH 4.3; diffuse change to:
B22	60-120 cm	Reddish yellow (10YR6/6), with many greyish brown (10YR5/2) mottles; clay; weak coarse parting to fine angular blocky structure; pH 4.3; diffuse change to:

Soil Profile Characteristics:

	pH	Salinity Rating	Sodicity
Surface (A1 horizon)	Very Strongly Acid	Medium	Non Sodic
Subsoil (B21 horizon)	Extremely Acid	Medium	Non Sodic
Deeper Subsoil (at 120 cm)	Extremely Acid	Medium	Non Sodic

This profile is very strongly acid at the surface, then extremely acid for the rest of the profile.

The profile has a medium salinity rating.

This profile is non-sodic.

The clay content moderate with a slow increase with depth.
