Global meals safety is below strain from local weather change, inhabitants progress, financial shocks and illness outbreaks.
Closer to house, we’ve all felt the pinch. Remember when floods wiped out lettuce crops and KFC changed iceberg lettuce with cabbage in its burgers? Or when bird flu sent the price of eggs soaring?
Add in fragile supply chains and a food waste disaster, and holding meals on our plates isn’t so simple as it sounds.
To preserve us fed, a farmer should be a jack of all trades and a grasp of science. So what does science appear like out within the paddock?
LOOK MUM, NO HANDS!
Driverless automobiles have been the topic of science fiction and hype for many years. But for farmers throughout WA, autonomous tractors have been a actuality because the mid-2010s.
Autosteer expertise – guided by GPS satellites – permits farm equipment to precisely seed and harvest crops like wheat, barley and canola. Self-driving tractors enhance time and useful resource effectivity.
Mingenew wheat and sheep farmer Rob Holmes says they’re exact.
“There’s a GPS receiver on the roof of the tractor,” says Rob. “It is a bit fancier than the one in your car, but it’s the same idea – it knows where you are, down to about a metre.”
While that’s correct sufficient for basic navigation, satellites can drift a little bit. Small errors add up shortly in agriculture. That’s why many farmers add a base station on their farm – an motionless GPS anchor.

“The base station is always talking to the tractor, sending those correction signals. If the tractor drifts even a little, the autosteer corrects it straight away,” says Rob.
“That’s how you get it down from a metre to just a few centimetres.”
“It’s how you get those neat, dead-straight lines across the paddock.”
Being a number of centimetres off sounds minimal. But once you’re seeding, spraying or harvesting crops throughout lots of of hectares, these errors multiply.
It’s like portray the identical patch of wall twice or lacking a strip when mowing the garden – however multiplied lots of of instances over.
Autosteer expertise has modified the way in which WA farmers work, rising crops on the identical quantity of land extra effectively. This means much less wasted crop area and extra meals grown – and stronger meals safety for all of us.
I SPY WITH MY LITTLE AI
While satellites are used to steer tractors remotely, AI performs a job too – by serving to farmers examine their grain one wheat kernel at a time.
Before grains might be made into sourdough, beer or oil, they should be totally checked for ailments and defects.
Co-operative Bulk Handling (CBH) receives tens of millions of tonnes of grain from throughout WA. CBH grades the grain when it’s acquired, which determines how, when and the place it may be bought.
Defects like sprouted grain, discipline fungi and frost damage all have an effect on a truckload’s last grade.
Carrying out visible checks for defects is a handbook course of undertaken by grain samplers, lots of of instances a day.
Enter CBH’s new visible evaluation grain sampler. This machine was developed in collaboration with Deimos.
“The great thing about the technology is we can analyse half a litre of grain in around 2 minutes,” says Craig McLure, Head of Grain Technology at CBH.
The printer-sized machine scans 1000’s of grain kernels from each side.
The gadget strikes the grain onto glass plates, which vibrate to make sure grain is evenly unfold.

Craig says high-resolution cameras {photograph} every kernel from the highest and backside.
AI software program then compares every particular person grain towards 1000’s of reference pictures. The AI seems for indicators of harm, illness or contamination that will in any other case take a educated eye time to identify and rely.
“The machine effectively deploys our very best sampler to every sample site in our network,” says Craig.
The visible evaluation machine isn’t just about pace. By catching defects early, it protects the standard of meals on our cabinets, in our kitchens and on our plates.
FROM LITTLE THINGS, BIG THINGS GROW
Farming isn’t one type of science: it’s all of them.
After all, the complete saying is “jack of all trades, master of none; is often better than a master of one”. In agriculture, carrying many science hats serves one objective: placing meals on the desk.
CBH Group supported the event of the brand new Global Food Solutions exhibit – a part of Scitech’s Here, There and Everywhere everlasting gallery transformation. The exhibit opened on 22 September.
