Sprint® 138 Turf and Greenhouse Nutrients

A 6% chelated iron micronutrient that produces superior results regardless of soil pH, Sprint 138 iron chelates help horticultural professionals solve plant health issues related to iron chlorosis.

It prevents iron from binding with other compounds in the soil, allowing it to stay in a form readily available for plant and turf use for improved quality and health.

With the highest ortho-ortho (5.2%) content available in the industry, Sprint 138® iron chelate provides plants 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. With Sprint 138® the ortho-ortho isomer represents 87% of the total chelated iron contained in the product – a big advantage in efficiency and performance.
