Soil management technologies showcased in the north

During late February and early March 2019, the GRDC Grains Research Updates for the northern region were held in Warra, Moonie and Goondiwindi in Queensland, and Spring Plains, Coolah, Dubbo, Corowa and Wagga in New South Wales.  A number of the presentations at the Northern Updates focussed on the new […]

The best resource on fertiliser N and legumes in the northern region

Balancing legume N with fertiliser inputs can be tricky. Legumes can affect soil N dynamics in unexpected ways. For example, chickpeas grown in low N soil can fix a large amount of N. But in high N soils, chickpeas use the soil N and fix less from the atmosphere. They […]

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 […]

Compaction concerns showing up in soil pits

Soil compaction caught the eye of growers and advisors at recent field days. Soil pits were part of every More Profit from Crop Nutrition roadshow field day. Soil scientists explained what they could see in the soil profiles. Crop nutrition relies on roots exploring the soil to access nutrients. Ideally, […]

Get the best nitrogen benefit from legume rotations

Legumes grown under ideal conditions can add 30 to 120 kilograms of nitrogen per hectare, per year, back into the soil for use by other crops. The benefit of legume rotations to the following crops comes when the nitrogen-rich legume residue has decomposed and released nitrogen into the soil. Wheat […]

Latest expert advice on deep banded fertiliser

Deep banding of phosphorus (P) and potassium (K) fertilisers has shown promising yield responses in some settings, but not in others. Deep-banding trials across Queensland and New South Wales have shown that banding rarely reduces crop yield, but it doesn’t always lead to profitable yield increases. Some of the variability […]

How to include ammonium-N in recommendations

It used to be that nitrate was often the only form of nitrogen (N) specified in soil test results. Now it’s common for soil test results to specify the quantity of ammonium-N as well. Recently some unusually high ammonium levels – equal to or higher than nitrate levels – have […]

Think twice before sowing chickpeas into high Nitrogen soils

leaf tips are dead

The current temptingly high chickpea prices make them an attractive option. In paddocks with high soil nitrate (>100kg N/ha) chickpeas may not yield as well as expected, or deliver the usual legume break crop advantage of a net benefit to the paddock’s nitrogen (N) balance. Paddocks can have high starting […]

Nitrogen Use Efficiency training online

Significant new research is investigating how management of nitrogen fertilizer can be optimised for crop profitability, alongside minimising greenhouse gas emissions and impacts on water quality. Fertcare® has brought this new information, along with a summary of existing best science and their practical implications into a training package. Following a […]

Deep Phosphorus fertiliser trials in NSW

Deep phosphorus (P) placement to improve crop productivity is being investigated in the central west of NSW, at Gilgandra and Nyngan. Led by Dr. Mike Bell (QAAFI), the trial investigates how deep P placement affects the fertility of the subsoil, and the economic effectiveness of deep P placement. The work […]

How Australian crop advisors make quality fertiliser recommendations

Crop nutrition and better fertiliser decisions for cropping webinar, presented on 8 October 2015 by Tony Cox, NSW DPI, National Coordinator for the More Profit from Crop Nutrition II program, funded by the GRDC. The webinar introduced the BFDC database and the Interrogator that enables crop advisors to ensure their […]
