Consistent Vermicast application will result in a completely rehabilitated soil. It takes time and how long it takes depends on factors such as the volume applied each time and the consistency of application protocols. The above sample was drawn from below a Macadamia tree that was four years old and had had vermicast applied at 4dm per year, every year. In this case the tree also received a compost application annually but no other fertilisers or compounds were added. The tree is healthy and has started to yield good quality nuts.
