In the realm of agricultural and horticultural science, micronutrients are as vital as macronutrients for optimal plant growth. Iron deficiency, or chlorosis, is a common issue that can severely limit crop yields and quality. Diethylenetriaminepentaacetic acid ferric sodium complex (DTPA-FeNa) has emerged as a leading solution for delivering iron to plants, offering superior stability and efficacy. For professionals seeking to buy DTPA-FeNa, understanding its properties and applications is key.

What is DTPA-FeNa?

DTPA-FeNa, with the CAS number 12389-75-2, is a water-soluble iron chelate. It is the ferric sodium salt of Diethylenetriaminepentaacetic acid. The 'chelate' structure means that the iron ion is held securely within a larger organic molecule (DTPA), preventing it from reacting with other soil components and becoming unavailable to plants. This chelating action is what makes DTPA-FeNa so effective.

Key Chemical Properties and Advantages

  • Appearance: Typically a yellow-brown powder.
  • Iron Content: Usually specified with a minimum of 11% chelated iron.
  • Solubility: Highly soluble in water, making it ideal for liquid applications.
  • pH Stability: This is a critical advantage. DTPA-FeNa remains stable and keeps iron soluble in a moderate pH range, generally between pH 4 and 7. This broad stability surpasses that of many other iron chelates, like some EDTA formulations, which can degrade at higher pH levels.
  • Non-injurious to Foliage: When applied as a foliar spray, DTPA-FeNa is gentle on plant leaves, allowing for direct and efficient nutrient absorption without causing damage.

Primary Applications in Agriculture and Horticulture

The stable and bioavailable nature of DTPA-FeNa makes it indispensable in several key areas:

  • Agriculture: Used to correct iron chlorosis in field crops, fruit trees, and vegetables. It is applied either through fertigation systems or as a foliar spray to ensure plants receive adequate iron for photosynthesis and overall health.
  • Horticulture: Essential for ornamental plants, greenhouse crops, and nursery stock, where visual appeal and vigorous growth are paramount. It helps maintain vibrant leaf color and promotes strong development.
  • Soilless Cultivation: In hydroponic systems, where plants grow without soil, nutrient delivery must be precise. DTPA-FeNa provides a reliable source of iron that remains available in the nutrient solution.
  • Ingredient in Fertilizers: DTPA-FeNa is an excellent additive for NPK fertilizers, creating complete formulations that address macronutrient and micronutrient needs simultaneously.
