Question

Is iron absorbed by plants both as ferrous and ferric?

Answer 1

The answer is Yes.

Yes, iron is not absorbed by plants as both ferrous and ferric forms. It is absorbed in both ferrous and ferric forms. Throughout their growth period, plants need a regular supply of iron. The ferrous ions absorbed at the roots are oxidized to ferric ions at the meeting point of the metaxylem and protoxylem. This is then chleated by the citrate and moved to the top of the plant by the metaxylem.

Answer 2

Ferric iron is the form of iron which has substances and compounds. It is referred as the iron with oxidization. It is a trivalent iron compound.

Ferrous iron is a divalent iron compound which is a +2 oxidation. 

In plants, most have ferric ions, hence iron is absorbed as ferric irons. 

However, advanced studies show that depending on the pH level, the plant can absorb iron in both ferric and ferrous form.
