Reports of iron deficiency chlorosis (IDC) of soybeans are coming in. The unifoliate leaves of soybeans are usually green, being fed by iron reserves in the seed, but as the trifoliolate leaves appear, chlorosis often develops when soybeans are grown on alkaline, poorly-drained soils. Iron is very immobile in the plant, so the deficiency appears first on the youngest leaves. Under severe conditions, the growing point is injured, recovery is limited, and yields are devastated.
