How to account for stubble nutrients next season

Stubbles can be a source of nutrients for next season. Different crops grown under different conditions have varying amounts of nutrients in their stubbles. Nutrient budgets can consider the amount and type of stubble.
How much stubble?

Stubble loads can be estimated from grain yield and the amount of growth. For cereals, […]

How to review Nitrogen nutrition at 3 timely points in the season

John Angus is a researcher with the CSIRO and a mixed enterprise farmer in southern NSW. At the 2016 GRDC research updates John reported on a three stage process to make strategic decisions about Nitrogen (N) nutrition through the season for dryland farmers.
Stage 1 – Prior to sowing
Prepare a Nitrogen […]

Test first, then time Nitrogen fertiliser to reduce losses

Optimal timing of Nitrogen fertiliser applications can maximise crop uptake and reduce losses to the atmosphere. Soil Nitrogen (N) dynamics in Victoria show some big differences between regions. High rates of N losses recorded from soils in the High Rainfall Zone (HRZ) emphasise how important timing of N applications can […]

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 […]

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.
Key […]

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 […]

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.
