DGT as the soil test of choice for predicting phosphorus requirements of grain crops

Plain text source: 
" DGT as the soil test of choice for predicting phosphorus requirements of grain crops.. Work funded previously by GRDC has shown that a new soil test sensor, known as Diffusive Gradients in Thin Films (DGT) provides an accurate measure of soil phosphorus available to wheat... The network of collaborators established in previous projects will be used to ensure as many regions and trials are accessed as possible - both current and archived soil samples will be analysed using DGT as well as the traditional Colwell, the resin test used by researchers and the Colwell plus PBI modification...
