Description

0–10

Dark brown (7.5YR3/3) with few faint red mottles; light clay; strong medium subangular and polyhedral, parting to fine and very fine subangular and polyhedral structure; weak consistence when dry; pH 8.5:

10–40

Brown (7.5YR4/3) with common faint red mottles; medium heavy clay; strong very fine polyhedral structure; firm consistence; a few soft and hard calcareous nodules; pH 8.5:

Limestone.

Management considerations

Uniform clay soil on Limestone.
Shallow soil.
High nutrient profile but limited depth (water holding capacity and rooting depth limitations).
Strongly structured, well drained despite high clay percentage.
Landform element is a undulating plain, imperfect site drainage.
