Western Australian researchers investigating biochar have unearthed some promising results about its properties... UWA Institute of Agriculture Associate Professor Daniel Murphy, who is leading WA research under the GRDC biochar project, said new studies had also shown that biochar did not affect the rate at which nitrogen was released from the decomposition of organic matter in soil... "Biochar is a stable form of carbon which can remain in the soil for hundreds of years - we need to be very sure about its attributes before making recommendations about its use," Professor Murphy said...

Applying P at depth (15 to 20cm deep on 50cm bands) can improve yields over a number of cropping seasons (if other nutrients are not limiting)... Limited P is now constraining yields in parts of the northern grains region, particularly in the vertosols (black and grey cracking clays)... The test needs to be done only every four to six years, and is most important in the subsoil layers...

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...
