This one-year investment aimed to provide growers and advisers along the South Coast of WA with greater confidence to make decisions on whether to sow a cereal crop later in the growing season (late winter, early spring) after crop failure, or inability to seed, due to early season waterlogging. It also aimed to provide some data on what varieties and nitrogen fertiliser strategies might be required for later sown crops.

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.
