Function of Iron Iron is a constituent of several enzymes and some pigments, and assists in nitrate and sulfate reduction and energy production within the plant. Although iron is not used in the synthesis of chlorophyll (the green pigment in leaves), it is essential for its formation.

Why do plants require iron?
Iron is an essential micronutrient for almost all living organisms because of it plays critical role in metabolic processes such as DNA synthesis, respiration, and photosynthesis. ... In plants, iron is involved in the synthesis of chlorophyll, and it is essential for the maintenance of chloroplast structure and function.
What plants benefit from iron?
Vegetables that prefer moderately acidic soils -- usually a soil pH of 5.5 to 6.5 -- prefer more iron than crops that prefer slightly acidic conditions and include turnips, tomatoes, squash and radishes. Those that prefer extremely acidic soils, such as radishes and sweet potatoes, enjoy iron-rich soils the most.
What happens if a plant lacks iron?
Iron deficiency, also called iron chlorosis or lime chlorosis, starts with a yellowing of the leaves in between the dark green veins, giving the leaves a spidery look. Over time, the leaves become whitish and start to die back, eventually resulting in stunting and dying back of the entire plant.
How do you know if a plant needs iron?
Symptoms for Iron Deficiency in Plants
The most obvious symptom of iron deficiency in plants is commonly called leaf chlorosis. This is where the leaves of the plant turn yellow, but the veins of the leaves stay green.
Is Iron bad for plants?
Like animals and people, plants need a certain amount of iron to survive. Iron helps them create chlorophyll and aids in several other chemical processes plants perform. However, too much iron can have a toxic effect on the plant, weakening and eventually killing it.
Can I use iron tablets for plants?
In plants where chelates are not naturally released, chelated iron can be used as a supplement to treat and prevent iron deficiencies ( University of Florida Cooperative Extension).
How do I add iron to my soil for plants?
So, how do you add iron to garden soil? You can add chelated iron powder or blood meal directly to the soil to add iron. You can also add fertilizer or your own compost, as long as the iron content is high enough. Another option is to add chelated iron or iron sulfate in liquid form by spraying the leaves of the plant.
How can I add iron to my soil naturally?
An easy and effective answer to iron deficiency in soil is natural foliar spray. This is a method that relies on spraying liquid fertilizer right on the leaves instead of applying fertilizer to the soil. Think of it as an iron supplement for plants and not necessarily for the soil.
Do plants like iron?
Iron is a constituent of several enzymes and some pigments, and assists in nitrate and sulfate reduction and energy production within the plant. Although iron is not used in the synthesis of chlorophyll (the green pigment in leaves), it is essential for its formation.
Which form of iron is best absorbed by plants?
Iron is absorbed by plants in the form of ferric ions.
What does iron deficiency look like?
Common signs and symptoms include tiredness, pale skin, feeling short of breath, and dry and damaged hair and skin. If you think you have symptoms of iron deficiency, talk to your doctor. Self-diagnosing is not recommended.
How are plants damaged by iron deficiency?
Development of a deficiency
Continued yellowing of the leaves to sometimes almost white. Also, large leaves turn yellow. This inhibits growth. In serious cases the leaves show necrosis, and the plant's growth and flowering are inhibited.
