N-rich strips show if your crop needs a boost this season

  An N-rich test strip in your paddock allows you to follow nitrogen supply in-crop, and see what responses are likely to additional N. The test strip is a part of the paddock where additional N is applied – above the base rate applied to the rest of the paddock. […]

Reducing Nitrogen losses in the High Rainfall Zone of Victoria

Strategies to reduce Nitrogen (N) losses in Victorian High Rainfall Zone (HRZ) cropping systems are getting clearer. Recent research in south western Victoria examined rates of N applied, placement of fertilisers and nitrification inhibitors. This work is part of the national agricultural nitrous oxide research program, supported by the GRDC. […]

Webinar – get more profit from nitrogen with price ratios

A free, online webinar to explain the concept of an economically optimum nitrogen rate. The optimum is derived using a ratio of the price of wheat to the price of nitrogen. This framework can help growers and advisors achieve better returns on nitrogen expenditure when used in conjunction with N […]

Using deep soil cores for Nitrogen, Potassium & Sulfur

Soil testing is a valuable tool for crop nutrition decision making. The standard 0 – 10cm soil test doesn’t always tell us enough about the crop availability of more mobile nutrients. Nitrogen and Sulphur, as anions (negatively charged), tend to move deeper into the profile with rainfall. On sandy acid […]

Subsoil manuring provides long term N supply

Some growers have been able to reduce N inputs for at least three years following the placement of manure into the subsoil. Trials in Victoria’s High Rainfall Zone by Southern Farming Systems are showing promising signs of multiple benefits from subsoil manuring. Originally, subsoil manuring was primarily for improving the […]

Top 10 crop nutrition articles 2015

During 2015 eXtensionAUS Crop Nutrition published 43 articles on many different aspects of crop nutrition in the Australian grains industry. All of these articles were prepared with, and reviewed by, members of our Community of Practice, Australia’s leading experts in crop nutrition. These are our top ten – the most popular […]

Webinar: Review crop nutrition in your paddocks

Webinar recording coming soon As part of the More Profit from Crop Nutrition national extension program,Chris Dowling presented a webinar for advisors and growers from all Australian grains regions covering the techniques for evaluating how the previous season’s crop nutrition delivered in terms of yield. The webinar covered what information you need, different measures of […]

Nitrogen – 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 on Nitrogen.     […]

How good was your crop nutrition last season? Tools for review

How do you assess how well last season’s crop nutrition management shaped up? Every grower knows how much they spend on crop nutrition. They do not always know if it was well spent. A good crop nutrition program maintains soil fertility, and supplies what is needed to meet the productivity […]

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 […]

What nutrients are lost when making hay from failed crops?

Cutting for hay is an option to get some economic value from a failed crop. Growers with an eye to the long term productivity of their paddocks weigh the value of the hay against the value of leaving the crop material in the paddock. Nutrients that would otherwise be recycled […]

Rain in the North – the flow on for crop nutrition

Rain received in late August in the northern grains region will help winter crops finish in NSW, but more is needed in September to make a great finish. Growers who have already top dressed should be happy, however the window is closing fast for growers to boost yield with extra nitrogen. […]
