Make better crop nutrition decisions with these tools

There are a variety of free and paid support tools to help make crop nutrition decisions. Please note this is not a complete list. Check out Climate Kelpie for more decision support tools. Free Tools SoilMapp collates data from national soil databases (ASRIS and ApSoil). View maps, photos and satellite […]

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 […]

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 […]

Is it worth targeting a jump up in protein grade?

Some significant global premiums are emerging for high protein wheat grades. These international prices are starting to flow through to domestic wheat prices. Prime hard wheat (standard is a minimum 13% protein) was recently quoted at a premium of $85/tonne over APW wheat (10.5% protein, 5% screenings, 12.5% moisture) in […]

Kick-start crops with compost

Compost can improve overall soil health and benefit crops. The organic matter may improve soil structure, infiltration and porosity.  The soil’s water and nutrient holding capacity may get a boost. Compost feeds the microbes in soil, which in turn increases soil fertility. Compost and nutrients Individual composts are different. The […]

The good, the bad and the ugly of topdressing opportunities

Topdressing decisions have to be made or revised, as the season progresses. The best nutrient use efficiency is achieved when nutrient supply matches crop demand. Splitting N applications through the season can better match crop demand than applying all N upfront, and allows some of the expense to be deferred […]

Root systems that respond to banded fertilisers

Crop varieties that can exploit fertiliser placed in bands could be crucial to future cropping yields and fertiliser use efficiency. Many of our cropping systems are slowly running down the native soil fertility. Ongoing cropping in these soils could depend more and more on nutrients placed into the soil as […]

Crop nutrition research put in the spotlight

The More Profit From Crop Nutrition II (MPCN II) initiative features in the July/August 2016 Ground Cover Supplement. MPCN II brings together more than 20 Grains Research and Development Corporation (GRDC) funded crop nutrition projects from across Australia with the aim of improving fertiliser input returns and nutrient use efficiency […]

Soil and water – Australian Agronomy 2015

The 2015 Australian Agronomy conference was held in Hobart in September 2015. The conference theme was Building Productive, Diverse and Sustainable Landscapes. Of the many presentations we have selected and grouped those we think are most of interest to Australian crop nutritionists. This is our selection soils and water.   […]

Carbon credits from fertilizer management

Cotton farmers could soon add value to their nitrogen fertilizer management by earning income in a similar process to graziers under the Emissions Reduction Fund (ERF) that recently passed through the Senate. Emissions reduction methods set out the rules for estimating emissions reductions from different activities, and ensure that emissions reductions […]

Be effective and efficient with N

Efficiency and effectiveness are different dimensions of nutrient use efficiency (NUE). The most efficient way to use fertilisers is not to use any, but that is not effective, as production is likely to be nutrient limited. IPNI’s Rob Norton gave a rundown on NUE terms and details, and how they […]
