This project aimed to explore different management strategies to overcome copper deficiency in cereals. The project compared the effectiveness of copper sulfate and copper chelate applied either as liquids banded at seeding or as a foliar spray. The project also evaluated the effect of different timings of application of the foliar sprays and their efficiency.
This project aimed to benefit local and South Australian farmers by establishing an independent best practice management guide for copper applications for the future.
The program demonstrated that:
• At some sites where copper deficiency was historically assumed, no response to any form of copper application was observed. Copper response is likely to vary by site and season.
• Yield loss caused by copper deficiency can be devastating to wheat yield.
• Soil and tissue testing can be useful in helping to detect low levels, but are not always definitive. Copper response appears to be dependent on other complex interactions such as soil moisture, yield potential and other constraints (N fertility etc.) and thus soil/tissue tests alone are not a definitive guide to future responses.
• Foliar applications performed better than in-furrow liquids.
• Chelate and sulphate products performed equally well when applied as foliar applications.
• Timing did not appear to be critical, with a wide band of opportunity from mid-tiller to early head emergence providing similar results
