As close as possible to the southwest corner of the AusPlots plot (i.e. outside and immediately adjacent to the plot), the soils are characterised by exposing the profile to a depth of 1 m+ by: 1. digging a pit, or 2. using a core tube or hand auger to collect soils and laying out the profile, or 3. collecting a 500 g sample from 10 cm increments down the profile to 1 m+ (by hand auger or pit).
