Manganese is essential in plant nutrition for the oxidation-reduction process. Specifically, manganese participates in the oxygen-evolving system of photosynthesis and in the photosynthetic electron transport system. In the soluble form, manganese is easily taken up from soils by plants and is rapidly translocated throughout the plant.

Iron Deficiency in Plants & How to Add Iron to Garden Soil ...

After all this talk of iron deficiency, it must seem impossible to have too much iron in your soil. However, it can happen, especially if you add iron without checking for other problems (pH level or levels of other nutrients). High levels of iron can cause manganese deficiency and disrupt photosynthesis. Conclusion
