| FUNCTION IN PLANTS |
OCCURRENCE UNDER DIFFERENT SOIL CONDITIONS |
- Necessary component of many plant enzymes.
- Occurs in chloroplasts where it participates in the photosynthesis and metabolism of N and S.
- Involved in the synthesis of chlorophyll.
|
- Content of plant-available Fe is low compared with total content of Fe in soil.
- Presence of Fe available to plants is at a minimum in neutral and alkaline soils.
- Deficiency can be induced by excess liming, "lime induced chlorosis", or by high levels of heavy metals.
- High levels of Mn can result in Fe deficiency in plants.
|
| DEFICIENCY SYMPTOMS AND CONSEQUENCES |
PLANTS PRONE TO DEFICIENCY |
- Can induce chlorosis, which starts in young leaves because of Fe immobility in the plant.
- In cereals deficiency is shown by alternate yellow and green stripes along the length of the leaf.
- Fe deficiency is often referred to as "twig dieback".

- Citrus, deciduous fruit trees, vine, bean, maize, tomato, roses and ornamentals.
