Grains and field crops
For a brief summary of objectives, site history and treatments see the 1969 summary of results. The results shown are of the yield of grain harvested from crops grown under various rotations of pasture ley. Quality (grain protein) is to be assessed on samples taken at harvesting. Plots on four of the trials are soil sampled before the start of the growing season and give an indication of nutrients available for crop growth. The trial W56H has the top 7.6 cms sampled and the other three the top 10 cms. Results of samples taken in 1971 have not been received from Government Chemical Laboratory. EX: W56H/604,
