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 […]

Kick-start crops with compost

Compost can improve overall soil health and benefit crops. The organic matter may improve soil structure, infiltration and porosity.  The soil’s water and nutrient holding capacity may get a boost. Compost feeds the microbes in soil, which in turn increases soil fertility.
Compost and nutrients
Individual composts are different. The source […]

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 […]
