As the global demand for sustainable and effective agricultural solutions continues to rise, EDDHA Fe 6% Organic Chelated Iron Fertilizer has emerged as a breakthrough product in the field of plant nutrition. Developed by Shijiazhuang Han Hao Trade Co., Ltd., this fertilizer combines cutting-edge chelation technology with organic principles to deliver optimal iron availability to plants under a wide range of soil conditions. In this article, we will explore the product's features, technical specifications, applications, and the company's commitment to innovation.

Product Overview

EDDHA Fe 6% is a highly specialized iron fertilizer designed to address iron deficiency in plants. Unlike traditional iron sources, which often become unavailable in alkaline soils, this product utilizes EDDHA (ethylenediamine di(o-hydroxyphenylacetic acid)) chelation technology to maintain iron solubility and bioavailability across a broad pH range. The product's microgranular formulation ensures ease of application while minimizing the risk of clogging in irrigation systems, making it an ideal choice for both small-scale gardening and large-scale agricultural operations.

Key Features and Advantages

One of the most significant advantages of EDDHA Fe 6% is its exceptional stability in diverse soil conditions. The EDDHA chelating agent forms a strong bond with iron ions, preventing them from reacting with other soil components and remaining accessible to plant roots. This is particularly critical in high-pH environments, where conventional iron fertilizers often become insoluble and ineffective.

Another key feature is the product's organic composition. As an organic iron fertilizer for plants, EDDHA Fe 6% aligns with eco-friendly agricultural practices. It supports sustainable farming by reducing the reliance on synthetic chemicals while promoting healthier soil ecosystems. Additionally, its micrograin structure ensures even distribution and rapid dissolution, allowing for efficient nutrient uptake by plants.

The product's versatility is further enhanced by its compatibility with various application methods. Whether used in foliar sprays, drip irrigation systems, or soil drenches, EDDHA Fe 6% adapts seamlessly to different farming techniques. This adaptability makes it a valuable tool for horticulturists, agronomists, and gardeners seeking to optimize plant health and productivity.

Applications in Agriculture and Horticulture

EDDHA Fe 6% is widely applicable across various agricultural and horticultural sectors. Its ability to deliver iron effectively in high-pH soils makes it particularly beneficial for crops such as citrus, grapes, and stone fruits, which are prone to iron chlorosis. In vegetable gardens, it ensures vibrant growth and prevents yellowing of leaves, a common symptom of iron deficiency.

For ornamental plants and landscape gardening, the product enhances the aesthetic appeal of foliage by maintaining a rich green color. It is also suitable for hydroponic systems, where precise nutrient control is essential. By addressing iron deficiencies promptly, EDDHA Fe 6% contributes to higher yields, improved crop quality, and greater resilience against environmental stressors.

Expert Insights and Industry Standards

The importance of chelated iron fertilizers in modern agriculture is underscored by the work of institutions like the National Institute of Standards and Technology (NIST). While NIST primarily focuses on metrology and technological standards, its research on material stability and chemical interactions provides a foundational understanding of how chelating agents function in complex environments. As noted in NIST's publications, "The development of stable chelating agents is critical for ensuring the reliability of nutrient delivery systems in agriculture" (NIST, 2025).

This aligns with the principles behind EDDHA Fe 6%, where the EDDHA chelating agent's stability across a wide pH range is a testament to advanced chemical engineering. By adhering to such scientific rigor, Shijiazhuang Han Hao Trade Co., Ltd. ensures that its products meet the highest standards of performance and safety.
