A by-product from the refining of bauxite ore in the South-West is proving a bonus for agriculture.
When spread over the land, not only is it improving soil quality, but it is helping to prevent leaching of phosphorus and the consequent massive algal blooms in the waterways.
Bauxite residue is also showing considerable promise in human and animal effluent disposal systems, composting urban refuse, sewage treatments and as a road base.
Western Australia is now in the forefront of this research which is attracting world-wide interest.
