How are you growing a great break crop?

The yields of ‘break crops’ are more important to farm incomes with higher prices for some non-cereal crops.  In 2017, 22.5 million hectares were sown to winter crops. Over 20% – 4.7 million ha – were non-cereals. In the period leading up until 2011, break crops were around 14% of […]

How to manage nitrogen in no-till residues

Crop residues influence the supply and uptake of nitrogen (N). In the long term, residues will improve soil fertility. Stubbles can immobilise soil N as they break down. Moisture makes a big difference to the rate of stubble decomposition and mineralisation of nitrogen in the soil.

How to improve results from dual purpose crops

Responsive nitrogen (N) management optimises grain yield and grazing value from dual-purpose crops. Dual-purpose crops are sown early, grazed during winter, then grown on to produce grain. For dual purpose crops in the southern region the framework for N nutrition should be:

Apply adequate N upfront to promote vigorous forage […]

New deep P tool calculates the benefits and payback for you

Subsoil phosphorus (P) deficiency costs growers in Queensland and Northern NSW around $80–100 million each year in reduced yield. Deep P fertiliser applications into the subsoil can improve yield but are a long-term decision. They are moderately expensive and returns are not immediate. The Deep-P calculator helps Northern region growers […]

Quality fertiliser decisions backed by science

Australian crop advisors can use the best available science to give fertiliser advice. The Better Fertiliser Decisions for Cropping (BFDC) database:

is the best available data resource
is continually upgraded with the latest field trial results
holds data from over 5,600 research trials looking at fertiliser response
underpins the recommendations of Fertcare […]

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 […]

Use paddock test strips to get the most out of your fertiliser budget

Paddock nutrient test strips showed two nutrient deficiencies in Justin Wundke’s barley crop. Justin and family run a cropping and prime sheep enterprise in South Australia.
Before sowing last year’s crop Justin knew his paddock could have an issue with sulfur deficiency. Justin set up some test strips in his paddock after […]

Last year’s most popular crop nutrition stories

eXtensionAUS Crop Nutrition published 49 articles in 2016. These were the most popular:

Can I burn lime and gypsum with stubble?

Bottom line: Loss of limestone will be minimal, gypsum might lose some solubility.
2. Three reasons why topdressing nitrogen can fail
Not enough rain after topdressing, too wet, too late!
3. The best frost tactics for […]

Compaction concerns showing up in soil pits

Soil compaction caught the eye of growers and advisors at recent field days. Soil pits were part of every More Profit from Crop Nutrition roadshow field day. Soil scientists explained what they could see in the soil profiles.
Crop nutrition relies on roots exploring the soil to access nutrients. Ideally, soil […]
