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. |
