Foliar-Pak Iron is a brand new, unique combination of iron and manganese that is protected by three different natural and modified plant metabolites. Each plant metabolite performs well in its own niche. The low-molecular-weight plant metabolites allow for movement through the stomatal pores and transcuticular pores; the high-molecular-weight modified plant metabolite chelates the iron and manganese for secondary uptake via the soil. This engineered redundancy ensures rapid uptake for the turf in all growing conditions.
