Description

A1

0–8

Very dark greyish brown (10YR3/2); light clay; massive (structureless); earthy fabric; very firm consistence when dry; highly calcareous; pH 9.0; abrupt and wavy boundary to:

B21

8–40

Dark grey (2.5Y4/1); medium clay; strong coarse to medium prismatic, parting to a medium to fine angular blocky structure; smooth ped-fabric; very strong consistence when dry; highly calcareous; few distinct slickenside cutans, pH 9.5; gradational and smooth boundary to:

B22k

40–70

Greyish brown (2.5Y5/2); medium clay; weak fine polyhedral structure; rough ped fabric; weak consistence when moderately moist; very highly calcareous; few extremely coarse calcareous soft segregations in patches; pH 9.5; diffuse and smooth boundary to:

B3

70–140+

Greyish brown (2.5Y5/3); medium clay; weak coarse polyhedral structure; rough ped fabric; weak consistence when moderately moist; highly calcareous; very few very coarse calcareous soft segregations in patches; few faint clay skins, pH 9.5.
Management considerations
  • High susceptibility to wind erosion
  • Alkaline subsoils with calcareous soft segregations in patches
  • Massive surface structure may make it vulnerable to wind erosion without stubble and trash retention
  • Possible slight to moderate soil structure decline susceptibility due dispersibility in the deeper subsoil
