A clearer picture for nitrogen in Australian soils

A national effort has been going into understanding Nitrogen dynamics in Australian soils. The driver is to help growers and agronomists refine their Nitrogen fertiliser decisions. The completed review reduces uncertainty around some of the soil processes involved in supplying Nitrogen to crops, and future research needs. The review characterised:

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 […]

Compost for agriculture – free training for advisors

A series of Fertcare® workshops across NSW will provide insight into the  benefits and impacts  of using composts in agricultural production, and skills in advising their use alongside conventional fertilisers. This free training is aimed at agronomists providing detailed soil and plant nutrition advice. The workshops are delivered by NSW […]

The good, the bad and the ugly of topdressing opportunities

Topdressing decisions have to be made or revised, as the season progresses. The best nutrient use efficiency is achieved when nutrient supply matches crop demand. Splitting N applications through the season can better match crop demand than applying all N upfront, and allows some of the expense to be deferred […]

How to include ammonium-N in recommendations

It used to be that nitrate was often the only form of nitrogen (N) specified in soil test results. Now it’s common for soil test results to specify the quantity of ammonium-N as well.
Recently some unusually high ammonium levels – equal to or higher than nitrate levels – have […]

Three reasons why topdressing Nitrogen can fail

A crop’s nitrogen (N) requirement rises when rainfall increases the yield potential. Applying more N fertiliser to meet greater plant N demand is often appropriate, but crop uptake is not guaranteed. Understanding why can help tailor topdressing practices to increase the chances of the applied N boosting crop yield and […]
