RIVERLAND horticulture growers are learning the art of turning fish waste into plant food in Loxton.
Australia's first aquaponic training facility is up and running with plenty of farmers lining up to be part of the action.
Aquaponics expert Andrew Dezsery said 20 farmers and commercial growers had been trained at the South Australian facility so far, four of who were now applying aquaponics systems to their growing practices.
A second training group is being formed.
Aquaponics is a sustainable system combining the cultivation of plants and aquatic animals in a re-circulating environment.
Mr Dezsery said he had been advocating aquaponics for more than 15 years.
"It's only now people are starting to say, we need to change our farming practices and help biosecurity," the #1Aquaponics general manager said.
Aquaponics uses less water than regular farming practices and does not use fertiliser, chemicals or pesticides.
It also allows crops to be grown in urban environments.
