An initiative by Kangaroo Island Seed Potato producers has led to the development of a major state wide project. There are scientifically documented challenges for the established soil testing methods (Colwell or Olsen P test) to reliably predict potato P requirements over a range of soil types. A project was developed by local producers in conjunction with Lyn Dohle (Rural Solutions SA) and submitted through Potatoes South Australia (SA’s peak potato industry body). The application was successful and the funds will be used to determine a more efficient method of soil testing using the DGT (Diffuse Gradient Thin Film test) developed by Dr Sean Mason at Adelaide University.
