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 newly emerging, young tissue. Young leaves show interveinal chlorosis.
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.
Reasons
Iron deficiency.
Iron fertilizers applied to the soil are often not effective, because they are rapidly converted to insoluble forms.
Iron deficiency is common in high-pH dryland soils. It is seldom seen in flooded soils.
With mild Fe deficiency, fading may be of a temporary nature only.
Fe efficiency varies among cultivars.
