Description

A

0–40

(depths variable) Fine sandy clay loam; pH 8.2.

B

40–70

(depths variable) Brown (7.5YR4/3) with few faint red mottles; light clay (sandy); strong coarse/medium prismatic and angular blocky structure (peds 10–100 mm); strong consistence when dry; pH 8.0.

C

70–150+

Light clay (sandy); abundant soft calcareous segregations; pH 8.8.
Management considerations
  • Gradational, alkaline (calcareous) profile
  • High amount of wind blown carbonates, some salts
  • Depths of horizons are very variable
  • Lunette, well drained site drainage
