Sprint 138 Chelated Iron-5 lb Bag

Sprint 138 is a chelated iron that will work on your plants and turf in extremely poor soil conditions up to a pH of 12. If you have poor soil but your pH isn't over 8, use Sprint 330. Iron is essential for the formation of chlorophyll, a vital component to ensure plant health. Since iron has low plant mobility, new growth in iron deficient plants often shows iron deficiency. In early stages, leaves have interveinal chlorosis where plant leaves are light green to yellow but the leaf veins remain green. In severe cases, leaves turn white and plants may die.

Iron deficiencies commonly occur in:

• Soils which are high in pH, calcareous, or have heavy clay which tie up iron.
• Plants which have a limited root system due to environmental, pest, or disease stress.
• Soils high in sand content due to poor nutrient-holding capacity.

Sprint chelated micronutrient formulations are important to plant health. Unlike non-chelated or weakly chelated irons, Sprint 330 and Sprint 138 are strong chelates that maintain and protect iron availability in a wide variety of problem soils. Plus, Sprint has the added flexibility for use in either foliar or soil applications. Sprint 138, a 6 percent fully chelated EDDHA iron, is preferred in the most challenging soils that are alkaline and calcareous, including soils with a pH greater than 7.0. Sprint 138 contains the highes ortho-ortho (5.2%) content available in the industry providing a highly efficient chelate that will keep working to “shuttle iron” from the soil to the plant for an extended period of time.
