Copper’s role is mainly as a reactive constituent of enzymes that catalyze oxidation and reduction reactions. Symptoms of deficiency in canola include interveinal chlorosis shortly after emergence, larger than normal leaves, wilting leaves, and a late flowering with the shortened flowering stem, but these have only been observed in pot experiments with severe deficiencies. The critical level of 0.30 ppm DTPA (diethylenetriaminepentaacetic acid)-extractable copper has been suggested for canola and this is much lower than the critical level for cereal crops. As a result, copper fertilization should probably focus on the cereal crops in the rotation.
