If we may accept that S removal in grain is lower than commonly accepted... S requirements of the trial yields could have been satisfied even considering an arbitrary figure of only 50% efficiency, except the Nyngan site... The figure of 50% above has no sound basis the author is aware of...

Planning S fertilisation for maintenance levels of 4 kg to 5 kg S/t of grain removed might be more suitable as a general rule... Canola requires higher inputs per tonne of grain for the major (macro-) nutrients N, P and S compared with other crops (Table 1)... Table 1: Comparison of the average quantity of major nutrients removed (kg/ha) per tonne of grain and stubble for a range of crops, including canola and wheat...

Three years of trials by the Grains Orana Alliance (GOA) in the central-west region of New South Wales have consistently failed to demonstrate a canola yield or oil response to the addition of sulfur, which challenges the current recommended practice for canola... Given that most canola growers apply 20 kilograms of sulfur per hectare as a matter this is likely to be reducing growers' profitability.".. None of the trials responded to sulfur in oil or yield...

Three years of trialling by GOA has consistently failed to demonstrate a significant response to the addition of sulfur (S) in yield or oil%... Numerous trials by other organisations recently have also failed to demonstrate responses to sulfur in canola... In summary, 20 trials have now recently been undertaken across a number of seasons and locations in NSW. None of them have demonstrated S responses in yield or oil %. This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high...

This does not exclude deficiency and yield penalties from occurring but does highlight that the frequency and the likelihood is not high... Delaying any action that has the potential to cease grain fill will see more seeds achieve their maximum size and improve yield... In summary there was no 'concerning' level of seed loss observed at any trial or timing, correlating well with the yield data...
