Vetiver Grass Hedgerows for Pollution Control
Machine planting of vetiver grass to create an artifical wetland for the treatment of effluent at a tannery north of Brisbane. The land between rows will be planted with pasture species to reduce nutrients and salt.

Note mechanical planting would seem to be the way to go on large commercial farms or sites and in countries where labor costs are increasing. another advantage of machine planting is that it can be done quickly at the optimum planting time.
