DTPA Fe (Iron Chelate)

Hydroponic Systems: The preferred iron source for recirculating nutrient solutions due to its stability at a neutral pH.
Foliar Spraying: Used as a fast-acting corrective spray for iron deficiency in ornamental plants and greenhouse crops.
Aquarium Maintenance: Safely used in planted aquariums to provide iron to aquatic plants without promoting excessive algae growth.

Iron DTPA, Fe-DTPA 7%, Diethylenetriaminepentaacetic acid iron salt.

DTPA Fe (Iron Chelate) (CAS 12389-75-2) is an iron chelate of diethylenetriaminepentaacetic acid, supplied as a yellow-to-brown powder or granule with 7% fully chelated iron, and is used in hydroponic systems, foliar sprays and planted aquariums. This Agricultural Grade yellow-to-brown powder/granule is significantly more stable than EDTA iron in difficult soil environments.

As a Specialty Chemical, it is widely used in high-tech horticulture and hydroponic systems to ensure a steady supply of iron without the risk of precipitation. The 7% Iron content is fully chelated, allowing for rapid absorption through both roots and leaf surfaces.

The product is exceptionally water-soluble and leaves no residue, making it ideal for precision farming and sensitive aquatic applications. It is chemically engineered to remain stable under UV exposure, ensuring long-lasting availability in outdoor irrigation setups.
