How much nitrogen are we losing?

Around 25–30% of nitrogen (N) applied to paddocks is lost each season in the northern region. Researchers are not recovering this nitrogen from the soil or the crop biomass. Isotope labelled 15N fertiliser is used to track fertiliser nitrogen through the cropping system. Field trials in NSW and Queensland with […]

A clearer picture for nitrogen in Australian soils

A national effort has been going into understanding Nitrogen dynamics in Australian soils. The driver is to help growers and agronomists refine their Nitrogen fertiliser decisions. The completed review reduces uncertainty around some of the soil processes involved in supplying Nitrogen to crops, and future research needs. The review characterised: […]
