Iron deficiency made worse by
- High pH
- Water logged soils
- Calcareous soils
- High copper, manganese or zinc soils
Iron is important for
- Photosynthetic activity
- Healthy young tillers
Symptoms
As iron is immobile within the plant, deficiency symptoms are first visible on the young, newly emerging tissue.
Leaves show an interveinal yellowing, then become uniformly chlorotic and show a pale yellow to white coloration. Growth is stunted.
With severe iron deficiency the whole plant becomes chlorotic and dies of.
Iron deficiency is common in high-pH dryland soils. It is seldom seen in flooded soils.
Reasons
Iron deficiency
Iron fertilizers applied to the soil are often not effective, because they are rapidly converted to insoluble forms.

With mild Fe deficiency, fading may be of a temporary nature only.

With severe Fe deficiency, top leaves become completely bleached and show a pale yellow to whitish discoloration. Interveinal yellowing spreads to older leaves as well.

Symptoms
Interveinal chlorosis on young leaves is the distinct symptom of mild to moderate lack of iron. With severe Fe deficiency, top leaves become completely bleached and show a pale yellow to whitish discoloration, while the interveinal chlorosis spreads to the older tissue too.
