Texture

The high clay content of the soils of units 5, 31, X31, and X32 with their large shrink/swell ratios
poses a serious limitation to their use. Unit X32 is particularly limited in this respect. It has the
highest clay content and widest shrink/swell of any mapping unit in the survey.

The soils of units 5, 31, and X31 are considered marginally usable for revegetation. Seedbeds in
these soils can be established with some difficulty but can be worked successfully only over a
narrow range of soil moisture. They would require careful management if used for revegetation
purposes. Unit X32 is considered unsatisfactory for seedbed material and would require very careful
preparation if soils of this unit are to be revegetated, even in their undisturbed condition.
