Implications of 2018 drought and frosts for nutrient management in 2019?

2018 provided many challenges for grain growers, with mother nature dealing out drought and frost and everything in between across Australia’s grain growing regions.  In light of these seasonal conditions and with harvest 2018 nearly over for many, what plans should you be making for your 2019 crop nutrition program? […]

Soil sampling to boost profit with variable rate technology (VRT)

Variable rate technology (VRT) means matching fertiliser or soil amendment rates to soil types, fertility, and yield potential. Trials in Western Australia  (WA) showed a gross margin increase up to $50/ha using VRT. Costs might stay the same but resources are better allocated. This can translate to improved yield. Because […]

More on crop nutrition from the 2018 GRDC Updates

The P story so far – Mike Bell At the Allora and Breezer updates, researchers from University of Queensland, DAF Queensland and NSW DPI gave an update on the latest deep P research findings. The P story so far – an update on deep P research findings Farming system impact […]

Nitrogen topical at 2018 GRDC Updates

Keep up with the latest research information on nitrogen. The following papers and key messages were presented at the GRDC Updates across Australia in February and March 2018. Improving N efficiency using mid-row banding – Graeme Sandral Mid-row banding urea at sowing provided a higher yield and profit response in […]

Research into mid-row banding benefits continues

In 2016, Agriculture Victoria researcher Ashley Wallace conducted mid-row banding (MRB) trials in Victoria. These were part of the GRDC/Agriculture Victoria Regional Research Agronomist program.The trials compared MRB nitrogen fertiliser in-crop to other application methods. MRB is when fertiliser is applied in concentrated bands below the surface to every second […]

Nutrient strategies for 2018

Given the very patchy 2017 season, how shall we approach crop nutrition in 2018?  In November 2017, Rob Norton gave a webinar for ExtensionAUS Crop Nutrition on this topic. Rob is the Regional Director for the International Plant Nutrition Institute (IPNI). The main crop nutrition strategies Rob suggested: do soil […]

Help Australia day mungbeans get what they need

Some rain around Australia’s northern region saw some last minute mungbean crops go in. The GRDC Mungbean Grownotes suggests we base fertiliser recommendations on: soil test results fallow length yield potential paddock history. That’s comprehensive, but with an opportunity crop there’s not always the chance to cover all the bases. […]

Top up nutrients after a good year

Nutrients leave the paddock with the grain. A good yield means more nutrients go out and less remain in the soil. Some nutrients may need topping up to maintain yields. How much topping up? Different grains contain varying amounts of nutrients. The table below gives estimates of the nutrients removed […]

Rob Norton recognised for excellence at fertiliser conference

Rob Norton

Congratulations to Rob Norton, who last night received an award recognising his long contribution to the Fertilizer industry, from Fertilizer Australia. Rob, the Regional Director of the International Plant Nutrition Institute (IPNI), is also the chair of extensionAUS’s crop nutrition Community of Practice. The award was presented at the conference dinner for the 2017 […]

Starter and residual P give strong early vigour in the north

Aerial photograph of starter and deep P trial site plots

This season, starter phosphorus (P) is producing strong early crop vigour. Deep P placement effects and the response to starter P are being documented at a long term monitoring site at Terry Hie Hie, in far north New South Wales.   The trial site compares plots with different rates of […]
