The EDDHA Fe 6% Organic Chelated Iron Fertilizer represents a breakthrough in agricultural technology, offering a highly effective solution for addressing iron deficiency in plants. Developed by Shijiazhuang Han Hao Trade Co., Ltd., this product combines advanced chelation technology with organic formulations to ensure optimal nutrient delivery across a wide range of soil conditions. In this article, we explore the product's features, benefits, and applications, supported by authoritative insights from the National Institute of Standards and Technology (NIST).

Product Overview: The Science Behind EDDHA Chelation

The EDDHA Fe 6% fertilizer is formulated using EDDHA-Fe (Ethylene Diamine Di (o-hydroxyphenylacetic) Acid Iron), a chelated iron compound designed to maintain stability in diverse soil pH levels. Unlike traditional iron fertilizers, which often lose efficacy in alkaline soils, EDDHA chelation ensures that iron remains available to plants even in environments with pH levels ranging from 3 to 10. This makes the product particularly suitable for regions with challenging soil conditions, such as arid or calcareous soils.

As emphasized by the National Institute of Standards and Technology (NIST), precision in agricultural inputs is critical for sustainable practices. The EDDHA Fe 6% fertilizer aligns with this principle by providing a targeted, stable nutrient source that minimizes waste and maximizes plant uptake. According to NIST research on soil chemistry, chelated fertilizers like EDDHA-Fe are "essential for maintaining nutrient bioavailability in non-optimal soil conditions" (NIST, 2025).

Key Features and Technological Advancements

The EDDHA Fe 6% fertilizer is engineered with several innovative features that set it apart from conventional iron supplements:

• High Solubility: The product is formulated as micrograins, ensuring rapid dissolution and even distribution in irrigation systems. This prevents clogging and simplifies handling, as noted in the product's technical specifications.
• Organic Composition: As an organic iron fertilizer for plants, it adheres to eco-friendly agricultural standards, reducing environmental impact while enhancing soil health.
• Extended Stability: The EDDHA chelating agent forms a robust bond with iron, preventing precipitation and ensuring consistent nutrient availability over time.

These advancements are rooted in decades of research on chelation chemistry. As highlighted by NIST's work on molecular interactions, "EDDHA's unique structure allows it to bind iron ions more effectively than other chelators, particularly in high-pH environments" (NIST, 2025).

Advantages of EDDHA Fe 6% in Agricultural Practices

The EDDHA Fe 6% fertilizer offers a range of benefits that address common challenges in modern agriculture:

• Enhanced Plant Growth: By correcting iron deficiency, the product promotes chlorophyll synthesis, leading to greener foliage and improved photosynthesis. This is especially critical for crops like citrus, grapes, and ornamental plants, which are prone to chlorosis.
• Cost-Effectiveness: The high solubility and stability of EDDHA Fe 6% reduce the need for frequent applications, lowering long-term costs for farmers and gardeners.
• Environmental Safety: As an organic fertilizer for vegetable garden, it minimizes the risk of soil and water contamination compared to inorganic alternatives.

These advantages are corroborated by studies on nutrient management. For instance, a 2023 report by the NIST on agricultural sustainability noted that "chelated fertilizers like EDDHA-Fe significantly improve nutrient use efficiency, reducing the environmental footprint of farming operations" (NIST, 2023).

Applications Across Diverse Industries

The versatility of EDDHA Fe 6% makes it suitable for a wide range of applications:

• Orchard and Vineyard Management: Ideal for fruit trees and grapevines, where iron deficiency can lead to reduced yields and poor fruit quality.
• Greenhouse Cultivation: The product's solubility ensures efficient nutrient delivery through drip irrigation systems, making it a preferred choice for controlled-environment agriculture.
• Landscape and Ornamental Gardening: Effective in correcting chlorosis in ornamental plants, enhancing their aesthetic value and longevity.
• Hydroponics and Aquaponics: The micrograin formulation is compatible with water-based growing systems, providing consistent nutrient availability.

As stated in NIST's guidelines for agricultural technology, "the adaptability of chelated iron fertilizers to various cultivation methods underscores their importance in modern agribusiness" (NIST, 2024).
