Iron Deficiency Chlorosis (IDC) is a common soil issue in some areas of the country. IDCtends to occur in soil with high pH levels, which can prevent plant roots from reducing iron to a soluble state that can be used by the plant. The problem isn’t necessarily the lack of iron in the soil, but more importantly the type of iron that’s available in the soil for plant uptake.Iron is commonly in a ferric (FE3+) state when it’s in the soil, but the plants’ roots need to reduce the ferric iron (FE3+) to ferrous iron (FE2+) to make it soluble for uptake by the plant.
