Description

At GRDC's National Grower Network (NGN) forums, growers have been asking for information about the cost of inorganic P fertilisers and potential lower cost options of organic P fertilisers. A GRDC investment to explore this topic has delivered some interesting outcomes and to find out the details we speak to Maurie Street from the Grain Orana Alliance, and Dr Tim McLaren from the University of Queensland.
