Research under the Grain & Graze program has found that despite tough conditions, Australia’s mixed farmers are continually adapting and surviving.
“Despite going through the driest five year period on record in Australia, we've been able to see a 9pc average increase in profit for mixed farmers participating in Grain & Graze program across Australia,” the program’s national co-ordinator, Richard Price, says.
“That is just testament to the resourcefulness of farmers.
"The great thing about mixed farming systems is that you can adapt to different climatic circumstances by adjusting the cropping-animal mix.”
As agriculture sails into waters made stormy by the cross-currents of climate change and soaring input costs, Grain & Graze pinned down diversity as a fundamental principle of farm adaptation.
Diversity starts with the mixed farm, an entity that has often been ignored in the commodity focus of research and lobby organisations, but which is at the heart of farming across southern Australia.
Researchers took a look at some of the enterprise mixes available to mixed farmers, like grazing of winter cereals, and identified the techniques that make these enterprise interactions successful.
Mr Price said that about 20pc of producers in the Murrumbidgee region grazed their cereals before Grain & Graze.
Now about 40pc use the strategy, many for the first time, and are reporting lifts in profits of up to 19pc.
The program also introduced the mixed farming sector to another pre-existing idea, integrated pest management (IPM), with highly encouraging results.
Used extensively in the cotton and broadacre grains sectors, IPM works by encouraging the natural predators of pest insects to operate on the farmer’s behalf.
Cam Nicholson, Grain & Graze’s south-west Victoria regional coordinator, said under IPM, insecticides become a tool of last resort rather than the first thing the farmer reaches for.
In one case monitored by the program, IPM reduced a farm’s insecticide use by 80pc.
Instead of simply counting pests and spraying when they reach a critical level, IPM asks that farmers and agronomists consider ratios of pests versus predators, whether beneficial species are building up and the pests reducing, and that the economic damage the pests are causing be coolly assessed.
Once a farmer has decided to work with “beneficials”, Mr Nicholson said, they need to begin practices that encourage beneficials while using “soft” options, like baiting, to discourage pests and change the ratios of insects in their crop.
“There's a fairly large shift in skill required, and the farmer needs a lot of confidence in the system.”
“But in our region (south-west Victoria) there’s been a fantastic response.
"We had 22 farmers and agronomists do the pilot course last year, and every single one has continued using it.
"They just think that it has got to be the way of the future.”
Grain & Graze program is jointly funded by Meat & Livestock Australia, Australian Wool Innovation, the Grains Research & Development Corporation and Land & Water Australia.
