- The Reefinator successfully crushed subsurface rocks to a size suitable for seed bed preparation.
- Two passes with the Reefinator was determined as the optimum to adequately bust up the rock; the first at 15cm deep and the second pass at 40cm deep.
- The FAE stone crusher can crush rocks to any size, right down to powder, but is very slow; soil chemistry is likely to be affected.
- Raised beds can now be formed to assist with the drainage and aeration in the crop root zone.
- The site will be monitored in 2018 to assess yield responses in comparison to previous seasons
