B22k

35-70

Greyish brown (10YR5/2); heavy clay; moderate coarse prismatic parting to moderate coarse blocky structure; weak consistence (moist); contains few (2–10%) soft carbonate segregations; pH 9.7; gradual boundary to:

B23

70+

Light grey (10YR7/2); heavy clay; pH 9.8.
Management considerations
  • Gradual increase in soil texture to heavy clay subsoil.
  • Vertic properties in deeper subsoil.
  • High calcium content in upper soil and higher magnesium and sodium and salinity levels at depth
  • Low topographic position, poor site drainage. Pale soil colours
