This investment aimed to locally validate previous R&D investment relating to spring sown crops (albeit include newer crop types and varieties where suitable), building local grower and adviser knowledge to inform decisions when managing excess soil moisture. It aimed to provide production and economic information from both farm-scale demonstrations and a small plot trial to inform good business decisions in regard to spring/summer sown crops.
The trials evaluated the crop performance on a range of metrics to provide a thorough assessment of summer crops, and the role they can play in agronomic systems, and the potential they have to reduce the waterlogging risk.
GRDC Outcome:
By February 2023, 20% of Western Region Growers who farm in areas with a medium to high-risk of regular waterlogging will have built the knowledge and confidence to profitably sow a crop in spring or summer on paddocks were winter crops/pastures have failed due to excessive waterlogging or where soil moisture levels permit in future years.
To achieve this outcome, Stirlings to Coast Farmers (SCF) worked with a number of other Grower Groups to ensure the key learnings of the trial were broadly and successfully extended to growers in the Great Southern Region of WA.
In 2021/22, six successful field trials were spread across the medium to high rainfall zones of the Central Wheatbelt, Great Southern and Southern Coastal regions of WA. Excessive winter waterlogging occurred in the 2021 season across all trial locations.
The results showed that:
