Unlike non-chelated or weakly chelated irons, these strong chelates maintain and protect iron availability in a wide variety of problem soils with the added flexibility for either foliar or soil applications. Sprint 330 is 10% fully chelated iron and performs best in slightly acidic to slightly alkaline soils with a pH of up to 7.5. Sprint 138 is a 6% chelated iron for the most challenging soils that are alkaline and calcareous, including soils with a pH greater than 7.0. May be incorporated mechanically, by rainfall, irrigation, soil drench or deep root feeding. Sold in 5 pound containers.
