Can I supply iron rust to the plants through roots in place of Fe?
Guest3430 Iron rust is the most stable form of Fe, so it is very unlikely that plants can get their Fe supply from rust.

In case of acute Fe deficiency in the soil, you can use any commercial foliar spray formulation containing all the micronutrients.
