Sprint 138 Chelated Iron 6% is a fully chelated EDDHA Iron that is very effective in fixing iron deficiency in calcareous and alkaline soils, as well as soils with a pH greater than 7.0. It helps prevent iron from binding with other compounds in the soil so it can stay in form. Adding Iron will ensure improved health and quality of plants. It can be used in nurseries, gardens, landscape plantings, and turf through soil application or foliar spray.

Key Features:

• Prevents and corrects iron deficiency
• Strongest chelate available for the most challenging alkaline or calcareous soils
• Works across a wide range of ornamental plant varieties in horticulture production settings
• Formulated to maintain and protect iron availability across all pH soils
• Flexible use as either foliar or soil applications

Why Iron EDDHA

• Plants with iron deficiencies will have pale yellow leaves and will not be able to produce the sugars requried to grow. Iron EDDHA fixes this issue, allowing for iron uptake (Wiersma et al. 2019)
• Unlike other iron sources which only work in low pH solutions, Iron EDDHA is effective up to pH 10 (Lucena et al. 2006)

Ingredients: Iron EDDHA powder

How to use:

Foliar spray & watering: Mix 5 Teaspoons per liter of water and use either as a foliar spray or water directly into soil/media* (solution will have a red color)

*Iron is not able to be moved into existing leaves from the soil so foliar application is necessary for existing growth, while watering into the soil will support new growth.
