Plants, in addition to other plant nutrients, need the element iron to grow well. Iron is an element that is essential for plants. Iron is primarily a component of enzymes and proteins. Iron is important for the formation of chlorophyll and therefore plays a central role in photosynthesis. Furthermore, iron has a significant influence on physiological processes and the plant's energy metabolism.

Iron deficiency

Although the element iron is only absorbed in minimal quantities by plants, a lack of iron can affect their development. Plants use iron during nitrate absorption, meaning a deficiency in iron can also mean insufficient nitrate uptake.
