Optimising sulphur and nitrogen nutrition in canola

This project aims to determine if nitrogen supply is limiting uptake of sulphur in canola crops grown in the Riverine Plains region and whether sulphur uptake and yield is increased in canola when nitrogen is available in non-limiting quantities.The 2017 project trial assessed the response to nitrogen and sulphur in canola crops of the Riverine Plains by determining:• the influence of nitrogen and sulphur application on canola tissue content, yield and oil• the fluctuation in nitrogen and sulphur content and nitrogen:sulphur ratio in the plant from stem elongation (GS31) to harvest (GS99)• the optimum available soil nitrogen level for the region’s canola crops at varying sulphur application rates.
