25–30

Yellowish red (5YR5/8) fine sandy clay loam; weak medium blocky structure; firm consistence (moist); pH 5.4; abrupt boundary to:

B21

30–45

Yellowish red (5YR5/8) medium clay; moderate medium blocky structure, parting to fine blocky structure; firm consistence (moist); pH 6.1; abrupt and wavy boundary to:

B22

45–65
Yellowish red (5YR4/6) medium heavy clay; weak coarse blocky structure, parting to moderate fine blocky structure; firm consistence (moist); pH 6.7; gradual boundary to:

B23

65–90

Strong brown (7.5YR5/6) medium clay; strong medium blocky structure, parting to fine blocky structure; firm consistence (moist); pH 7.0; gradual boundary to:

B3

90+

Strong brown (7.5YR5/6) with (5YR5/6) and (2.5YR5/8) mottles; very fine sandy clay loam; weakly structured; very firm consistence (slightly moist); pH 7.3.
Management considerations
  • Strong texture contrast between surface (A) horizon and the upper subsoil (B21) horizon
  • Massive structured surface (A1 and A2)
  • Strongly acidic profile
  • Mottled subsoil (B3)
