Sprint 330 & 138 High Performance Iron Chelates
For dark green, healthy plants, Sprint® 330 and Sprint 138 iron chelates are unquestionably the best iron products available. Unlike non-chelated or weakly chelated irons, the strong Sprint iron chelates maintain and protect plant available iron in turf, containerized and field grown plants, trees and shrubs.
Sprint 330: • 10 percent fully chelated DTPA iron • performs best in slightly acidic to slightly alkaline soils with a pH of up to 7.5
Sprint 138: • 6 percent fully chelated EDDHA iron • for soils that are alkaline and calcareous, including soils with a pH greater than 7.0
