|The surface soil is slightly acid. The subsoil is strongly alkaline becoming very strongly alkaline at 70 cm depth, before dropping back to moderately alkaline.||The salinity rating is very low in the surface and low in the upper subsoil becoming high with depth.||The surface is non-sodic. The subsoil is strongly sodic.||There is a sharp increase in clay at the surface / subsoil boundary.|
