This video summarises more than 10 years of research findings and practical 'Rules of Thumb' to help grain growers to make the best use of their existing, and potential (mineral) soil nitrogen; reducing both fertiliser nitrogen application and nitrous oxide emissions. Victorian researchers are adding to the growing body of evidence indicating that significant amounts of applied nitrogen fertiliser remains unaccounted for, under certain cropping systems and conditions. Presumably, this nitrogen is being irretrievably lost from the cropping system; representing both a significant cost to growers, as well as having a negative impact on the environment, especially through nitrous oxide emissions.
