Why Fertilise Wise?
River health, human health
Our river systems and many wetlands are in a poor state of health, judging by the undesirable and sometimes toxic algal blooms that occur regularly during warmer months. Although algae are plants that grow naturally in our rivers and wetlands, when they bloom, they are unsightly and foul smelling, prevent recreational use of the river, can be toxic to humans and animals, and kill aquatic fauna by starving them of oxygen.
High levels of phosphorus and nitrogen in our river systems and wetlands promote the growth of problem algae. Lawn and garden fertilisers are one of the largest threats as these nutrients added to our sandy soils are easily leached.
You can reduce the amount of nutrients you contribute to waterways by being Fertilise Wise.
