SEQUESTRENE 138Fe Iron Chelate 6% for Alkaline Soils 5lb bag

Sequestrene 138 6% fully chelated EDDHA iron chelate helps prevent iron chlorosis by maintaining and protecting iron availability in the most challenging soils that are alkaline or calcareous. It prevents iron from binding with other compounds in the soil, allowing it to stay in a form readily available for plant use for improved plant quality. Sequestrene 138 iron chelate provides plant-available forms of iron for an extended period of time. Numerous studies have shown that the EDDHA ortho-ortho isomer is superior in performance, especially in alkaline and calcareous soils.
