Iron Needed for Plant Growth
Iron is one of the 19 essential nutrients plants need for healthy growth. It is a micronutrient, meaning that it is not needed in high doses. But it is important, not only as a constituent of chlorophyll, but also as part of iron proteins involved in photosynthesis, nitrogen fixation and respiration. Lack of iron can lead to interveinal chlorosis and necrosis. Photosynthesis and cellular respiration are both processes that allow plants to make ATP. ATP is short for adenosine triphosphate; it is a high-energy molecule used for energy storage by organisms. ATP will provide the energy for other metabolic processes in the plant life cycle.
added iron in plants proven to be beneficial to human health
Dartmouth Professor of Biological Sciences Mary Lou Guerinot, the principal investigator on a study to improve iron content in plants, says, "Iron deficiency is the most common human nutritional disorder in the world today, afflicting more than three billion people worldwide. Most of these people rely on plants for their dietary iron. However, plants are not high in iron, and the limited availability of iron in the soil can limit plant growth".
Iron Oxide in Fertilizers
Alkaline soils make iron and other micronutrients unavailable to plants. Chlorosis is the yellowing of leaf tissue due to a lack of chlorophyll. Chlorosis in the younger leaves of a plant characterizes an iron deficiency. The tissue between the veins gradually turns yellow, while the veins tend to stay green. The tips and margins of some leaves may turn brown and become dry and brittle.
