Can trace elements affect nitrogen use efficiency in crops?

Any kind of nutrient deficiency can reduce crop yields. Trace elements are only needed in small amounts but untreated, deficiencies can cause important crop losses. Also, crops won’t make the most of nitrogen (N) fertiliser if they can’t access the trace elements. Nutrient use efficiency is a measure of how […]

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 […]

Fertcare® Nitrogen Use Efficiency workshops

Applying the right form of nitrogen fertilizer at the right rate, at the right time and in the right place has important implications for crop profitability, greenhouse gas emissions and water quality impacts. The Fertcare® and Cotton Info Team is facilitating a Nitrogen Use Efficiency (NUE) workshop for Fertcare® participants […]

Do you know your Nitrogen Use Efficiency?

Water use efficiency is widely recognised as a key performance indicator for crop production. Similarly nitrogen use efficiency (NUE) is an important indicator of resource use effectiveness and economic performance of this important crop input. Why measure NUE? Nitrogen fertilizer is frequently the biggest single cost within cropping variable costs. With […]

Things to consider when applying nitrogen fertiliser

There are a few key points to consider before applying nitrogen (N) fertiliser:   Nitrogen is the nutrient removed in the largest quantities in grain at harvest. Pulses in the system can provide some free N. Calculate a few target yields using one of the many tools available that vary yield […]

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 […]

Use tissue tests to detect deficiencies

Micronutrients or trace elements are an essential part of crop nutrition. They are as important as the better-known macronutrients nitrogen, phosphorus and potassium. This was a key message on the southern tour of the MPCN II Roadshow in August 2016. Scott and Jillian Vaessen farm at Tabbita in southern NSW. […]

Nitrogen management key driver of WUE

The rate of nitrogen (N) fertiliser applied is the stand-out variable influencing water use efficiency (WUE) in wheat crops. This was the main finding in a four-year research trial in western Victoria. Ten variables accounted for a third of the WUE variation between sites. Trial set up Data collection points […]

What is the fate of nitrogen fertiliser?

Do you know the fate of nitrogen (N) fertiliser that’s applied to cropping paddocks?  How much ends up in the crop, soil or lost? Victorian researchers have been working with a traceable N fertiliser to find out. The standard assumption is the crop takes up half the fertiliser N in […]

The latest on Nitrogen at the 2017 GRDC Updates

Managing N loss risks – Chris Dowling Practical N management can minimise the economic impact of N loss events. Chris Dowling from Back Paddock Company presented at the Bellata Update. Denitrification and managing nitrogen loss risk – key factors affecting loss. Nitrogen application – Richard Daniel The rate of nitrogen […]

When can you get the best results from late nitrogen?

Applying nitrogen late in the crop’s development (after GS60) can boost the protein level in the grain, but when is it likely to be economic to do so? When leaf symptoms or comparison with an N-rich strip in the paddock indicate the crop really needs more N. When N can […]

Timing is more important than form with nitrogen

Getting the timing right for topdressed N fertiliser to best match crop demand is more important for N use efficiency than choosing the right N fertiliser form. Field experiments generally show that granular urea, urea solutions and UAN perform equally well in supplying N when used in-crop. The most common […]
