Micronutrient deficiencies – real but unpredictable

Micronutrients or trace elements are often suspected to be deficient in some Australian cropping regions. Some trace element applications are now routine. But recent trials in areas with reported deficiencies have shown little response to micronutrient applications.
Micronutrient trials
In southeastern Australia, 23 trials were run on wheat, barley and canola […]

Crop nutrition field day provides local solutions

Researchers, agronomists and leading grain growers came together in July and August for a series of successful on-farm workshops presented by the More Profit from Crop Nutrition II (MPCN II) project.

Findings from recent soil and plant nutrition research were outlined by crop nutrition and agronomy researchers, followed by in-depth […]

What can you do with waterlogged paddocks?

How do you make evidence-based decisions following excessive rain and slow soil water drainage? Where the crop is not a write-off, getting a handle on which areas of the paddock are in the best shape, and the yield potential for those areas is the most useful information to have.
Assessing crop […]

Watch our webinar: how to review last season’s crop nutrition decisions

You might know how much you or your client spent on crop nutrition last season, but do you know if it was well spent? Review at the end of the season is the best place to answer that question. How do you assess how well last season’s crop nutrition management […]

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 efficiency, what […]

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 […]

Zinc deficiency shows up in the cold

The cold snaps seen in southern Australia this year gave conditions where zinc deficiencies typically appear. Zinc deficiency tends to occur early in the growing season when soils are cold and wet. Shoot growth then outpaces root development. Root-pruning herbicides can induce zinc deficiency by the same mechanism. Zinc deficiency […]

Correcting micronutrient deficiencies

Ross Brennan from DAFWA talks about a current micronutrient project funded by the GRDC as part of the More Profit from Crop Nutrition II Program.
Recent GRDC funded research in Western Australia showed that both foliar sprays and nutrient applications to soil are very effective in correcting micronutrient deficiencies in crops. Applying […]

Diagnosing crop problems

Sampling soils and plant tissues during the growing season can help diagnose symptoms that are seen in crops. Where patches of poor growth are seen, either soil or plant tissue samples from within the good and poor patches can be taken and sent for analysis.
For plant tissue samples, cut around […]
