Fertiliser and Crop Management of Areas at Risk of Flooding locations
Aims

To examine fertiliser and crop management of areas at risk of flooding.

Key messages

• Wheat was surprisingly tolerant of continuous flooding for nearly 4 months, yielding up to 2.8 t/ha with the best combination of nutrients tested.
• Despite the extended flooding there was a 13% response to P at a starting Colwell P of 29 mg/kg, with an economic optimum application rate of 7 kg P/ha.
• Canola was intolerant of extended flooding, producing no harvestable yield.
• In-crop application of urea shortly before flooding showed no grain yield response in wheat, while there was a negative response of 9% to applying S as in-crop sulfate of ammonia.
• Ideally in-crop applications of fertiliser should be made at least a week prior to flooding to allow time for the crop to take up the nutrients.
