Deficiency:- Interveinal chlorosis primarily on young tissue, which may become white;Fe deficiency may occur even if Fe is in the soil when: soil high in Ca, poorly drainedsoil, soil high in Mn, high pH, high P, soil high in heavy metals (Cu, Zn), oxygendeficient soils or when nematodes attack the roots; Fe should be added in the chelate form; the type of chelate needed depends upon the soil pH; foliar fertilization will temporarily correct the deficiency; may be deficient in centipede grass where pH and P are high

The principal veins remain conspicuously green and surrounding portion of theyounger leaves turn yellow tending towards whiteness in chickpea; groundnut; radish, cauliflower, cabbage and sorghum; lentil and soybean. Under sever deficiency;most part of the leaf becomes white.

Deficiency:- New growth small, misshapen, wilted; may be found in some peat soils;in some species young leaves may show interveinal chlorosis while tips of older leaves
remain green. In copper deficiency, visible foliar symptoms appear on young leaves as chlorosis changing to necrosis; rolling, wilting and twisting of leaves in wheat. Thelater affected leaves appear papery and twisted in rice.
