Protected cropping: Can it save Australia's salad and fruit bowls from harsh weather?

Published Jul 19, 2022

Tridge summary

Extreme weather in New South Wales and Queensland has led to a significant increase in lettuce prices, but farmers who use protected cropping have been less impacted. Protected cropping, which includes high tunnels, greenhouses, and fully indoor structures, allows farmers to control the plant's environment, including temperature, water, and soil. This can protect plants from adverse weather conditions. Professor Paul Gauthier from the Queensland Alliance for Agriculture and Food Innovation emphasizes that even in a storm, as long as the building can withstand the storm, the plants will be safe and production can continue.

Now experts say protected cropping could be the key to successful cultivation and getting farmers back to planting after extreme weather. Protected cropping is more than just greenhouses, says Paul Gauthier, a professor of protected cropping with the Queensland Alliance for Agriculture and Food Innovation. He says there are three different types of protective cropping. "It can be a high tunnel that protects the crop from the weather, it can be inside a greenhouse, or it can be in a structure where it is fully indoors, and the plants never see the sunshine." Protected cropping allows farmers to control the environment of the plants they grow, including the temperature, water, and soil in some systems that use hydroponics. Professor ...
