B22k	50–140	Reddish yellow (7.5YR7/6); light clay; strong coarse and medium, parting to medium subangular blocky structure; many soft calcareous segregations; pH 9.1:
B23k	140–170	Reddish yellow (7.5YR6/6); medium clay; moderate coarse prismatic, parting to strong coarse subangular blocky and moderate medium blocky structure; smooth ped-fabric; many soft calcareous segregations.
Management Considerations
Clayey profile, possibly a calcarosol (calcareous throughout). Clay content highest in upper subsoil. Subsoil dispersive when worked when wet. Strongly alkaline subsoil, but not sodic at least to 140 cm dominated by calcium. Gilgai micro-relief, caused by the soil cracking when dry, has lead to grey soil occurring in the depressions. Gentle Hillslope, imperfect site drainage.
