Sprint 330 and Sprint 138
High Performance Iron Chelate for Hydroponic, Foliar and Fertigation.
Iron is a key component of many critical enzymes in plants. It is one of the essential elements required for biological nitrogen fixation, sulfur metabolism and photosynthesis. It is also a critical element for oxygen transport in chlorophyll production. Iron chlorosis occurs when plants are unable to extract sufficient iron from the soil. This condition commonly occurs in:
- Soils that are high in pH, calcareous or have heavy clay that ties up iron.
- Plants that have a limited root system due to disease, pest or environmental stresses.
- Soils with high sand content and poor nutrient-holding capacity.
In the early stages of iron deficiency, new growth foliage exhibits interveinal chlorosis, in which leaf veins remain green but plant leaves are light green to yellow. In severe cases, leaves turn white and plants may die.
How can iron deficiency be prevented? Including Sprint® iron chelate products in your plant management program helps maintain and protect iron availability in a wide variety of problem soils.
Sprint iron chelated fertilizer products protect iron by preventing it from binding with other compounds in the soil, allowing it to stay in a form readily available for plant use.
Sprint 330 10% fully chelated DTPA iron performs best in slightly acidic to slightly alkaline soils and hydroponic solutions with a pH of up to 7.5. Sprint 138 6% fully chelated EDDHA iron is preferred in the most challenging soils that are alkaline or calcareous.
With the highest ortho-ortho (5.2%) content available in the industry, Sprint® 138 iron chelate provides plant available forms of iron for an extended period of time. Numerous studies have shown the EDDHA ortho-ortho isomer is superior in performance, especially in alkaline and calcareous soils.
