Crop Nutrition

Give seeds the best chance by avoiding fertiliser damage

Germinating seeds can be damaged by fertiliser placed too close or applied at too high rates. You can check how much fertiliser you can safely drill using the seed damage calculator. The amount of fertiliser that can be safely placed with seed depends on:
Crop type
Overall canola and lentils are particularly […]

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 […]

Tips to tweak your crop nutrition program following drought

Following drought growers look to recover production and protect vulnerable soils. When it comes, the break may present opportunities to cut back on some usual nutrient inputs while moving back into production. Soils should be managed with an eye to their long term fertility.
Phosphorus
Soil phosphate levels may increase a little […]

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

An N-rich test strip in a canola crop at Branson Farms, South Australia.
 
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 […]

What’s the minimum Phosphorus rate if you are following a poor crop?

Many growers will be thinking about what to do with Phosphorus (P) fertiliser for their next winter crop. Soil tests are the best indicator of whether a paddock is going to be responsive to P fertiliser.
If your soil tests shows moderate to good levels of P, and yields were […]

Using Potassium to put more profit on the bottom line

Potassium nutrition is a key part of crop agronomy. Under the GRDC’s More Profit from Crop Nutrition program, Professor Richard Bell from Murdoch University and collaborators investigated Potassium (K) nutrition in Western Australia; to help growers and advisors better understand crop responses to K inputs in different situations.
A free […]
