IRON

Iron is a component of many enzymes associated with energy transfer, nitrogen reduction and fixation, and lignin formation.

Metal Imbalances

Iron deficiencies may be caused by an imbalance with other metals such as copper (Cu), manganese (Mn) and molybdenum (Mo).

Chlorosis

Plants deficient in Fe will often display a pale green leaf color (chlorosis), with sharp distinction between green veins and yellow interveinal tissues.

Foliar Sprays

Most Fe fertilizer sources work best applied as foliar sprays.

Chlorophyll Formation

Iron is a catalyst to chlorophyll formation.

Oxygen Carrier

Iron acts as an oxygen carrier in the nodules of legume roots.

Iron deficiency symptoms

Symptoms of deficiency can vary across crop species, but similarities exist for how nutrient insufficiency impacts plant tissue color and appearance. Nutrient deficiencies are commonly associated with the physical location on the plant (i.e., whether the symptoms are primarily observed on older versus newly formed plant tissue), but these symptoms can spread as the severity of the deficiency progresses.
