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. […]

2015 crop prospects & Nitrogen

Some fertilizer goes on at or just before sowing. As the season progresses we need to: revisit paddock yield potential decide if, when and how much to top up Nitrogen (N). Splitting applications of N fertilizer through the season is a way of increasing nitrogen use efficiency, and better matching […]

Nailing nitrogen applications

For Wimmera and Mallee farming businesses, fertiliser is the biggest variable expense.  Creating Nitrogen (N) budgets based on predicted yields makes sense. N budgets start with realistic target yields based on predicted rainfall for the growing season. For wheat it is calculated as yield (kg/ha) = (growing season rainfall (mm) […]

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 […]

Will mid-season N be worth it?

As the winter cropping season progresses, some fortunate growers may be considering in-crop nitrogen (N) applications.  At the 2016 GRDC research updates, CSIRO researcher and mixed farmer John Angus discussed when and how to review N nutrition during the season. Once a cereal crop has emerged, the key times to […]

Sow close to the row to boost crops after a dry year

On-row or edge row sowing means sowing a new crop immediately alongside or in the previous crop row. Grain crops are usually sown inter-row (between the old crop rows). On-row sowing for phosphorus On-row sowing can make use of last year’s phosphorus (P) fertiliser. Phosphorus is not a very mobile […]
