Other claims from this paper (8)
- Observation Corn plants developed zinc deficiency at high phosphorus and low zinc.
- Observation Corn growth was greatest with 130 ppm phosphorus and 2.5 ppm zinc applied.
- Intervention effect Phosphorus and zinc fertilization altered the distribution of zinc, iron and manganese across corn leaves, stems and roots.
- Observation Zinc mobility varied opposite to iron and manganese mobility in corn.
- Intervention effect Applied phosphorus reduced corn tissue zinc concentration.
- Intervention effect Applied phosphorus did not reduce zinc uptake per corn plant.
- Observation Zinc-deficient corn plants accumulated excess iron.
- Mechanism The authors suggest excess iron interferes with physiology in zinc-deficient corn.
