Grains and field crops
This trial was put onto a site adjacent to Mel Mason's source of nitrogen trial and the CSIRO, 15 N plots to provide some explanation of the results from the limited treatments in those trials. They were designed to monitor soil/fertiliser nitrogen transformations with time. Unfortunately the site of this trial was variable. The end most similar to the other trials was deeper and sandier and stored less water than the other and where crop growth was far better.
