Iron (Fe) Nutrition of Plants - University of Florida

2018-1-31 · Iron uptake by the plant is not as simple as with other essential elements. Iron is taken up by plant roots in greatest amounts in the zone of the root between cell elongation and maturation, about 1 to 4 cm behind the root tip. Uptake of Fe by the plant is an active process, that is, energy is expended by the plant to take in Fe. Iron uptake

2007-5-25 · 1.. IntroductionIron (Fe) is an essential nutrient for plants. It is required for life-sustaining processes from respiration to photosynthesis, where it participates in electron transfer through reversible redox reactions, cycling between Fe 2+ and Fe 3+.Insufficient Fe uptake leads to Fe-deficiency symptoms such as interveinal chlorosis in leaves and reduction of crop yields.
