The primary symptom of iron deficiency is iron chlorosis, the development of a yellow leaf with a network of dark green veins. of iron (and the amount needed to support new red cell production to replace those cells lost through senescence) is about 20 mg. As humans only absorb 1–2 mg iron/day, 90% of the iron needed to replace dying red cells comes from iron recycling processes. In the other two blocks iron chlorosis was moderate at the time of application of treatments. An iron deficiency in plants causes unsightly ... like enzyme and chlorophyll production, nitrogen fixing, and development and metabolism are all dependent on iron.
