Other claims from this paper (9)
- Observation Soil and tissue micronutrients exceeded deficiency thresholds.
- Intervention effect Significant grain yield increases from foliar micronutrients were few.
- Intervention effect Foliar Zn raised leaf Zn by 4 to 9 mg Zn kg−1 at 5 of 17 sites.
- Intervention effect Foliar Fe raised leaf Fe by 8.1 mg kg−1 on average across ten deficient sites.
- Intervention effect Foliar B concentration was not affected by B application.
- Association Leaf nutrient concentration increases were unrelated to yield response except for Mn.
- Intervention effect Foliar Fe increased grain yield by 0.4 Mg ha−1 at deficient sites.
- Recommendation Foliar Fe may be profitable when deficiency symptoms are seen.
- Recommendation Other foliar micronutrients are unlikely to be profitable without deficiency evidence.
