Propel is a concentrated (10,000 mg/L) source of ferrous iron. This ferrous iron is a mixture of readily available and time-released iron
Iron is immobile in plants; this means that plants cannot deliver iron from older leaves to new ones. Therefore, deficiency symptoms appear first on new or young leaves. Because plants use iron to produce chlorophyll, a lack of iron results in chlorosis, or yellowing, of the younger leaves.
