APPLICATIONS
Uses & crop applications
EDTA-Fe supplies chelated iron for a broad range of crops and application methods, and helps correct iron chlorosis (leaf yellowing) on many soils.
- Drip irrigation and fertigation (water-fertilizer integrated systems)
- Hydroponic nutrient solutions and soilless growing media
- Liquid fertilizer formulations
- Foliar spray on flowers, fruit trees, and field and horticultural crops
- Practical iron correction on many soils; note that on high-pH or calcareous soils EDDHA-Fe stays more stable
