These are soil profiles taken from the trial. On the left is a core from the continuous cropping/no fertiliser field, and in the middle is one from the 50% pasture rotation. Although both soils naturally crack vertically, only the pasture rotations showed organic matter going deep in to the profile. It may be fluke that the samples were taken in these places, but it was consistent across all five cores they had on display. On the right is a close up of the higher organic matter soil from about a meter deep
