Introduction

The EDDHA Fe 6% is a groundbreaking organic chelated iron fertilizer designed to address the critical need for efficient nutrient delivery in agriculture. This product leverages the stability of the EDDHA (Ethylene Diamine Di (o-hydroxyphenylacetic acid)) chelating agent to ensure optimal iron availability across a wide pH range. Developed by Shijiazhuang Hanhao Trade Co., Ltd., this fertilizer is a testament to innovation in sustainable agriculture. In this article, we delve into the features, benefits, technical specifications, and applications of this product, supported by authoritative insights from the National Institute of Standards and Technology (NIST).

Product Overview

The EDDHA Fe 6% is a water-soluble, microgranular fertilizer that combines organic chelation with advanced formulation technology. Unlike traditional iron fertilizers, which can become ineffective in high-pH soils, this product maintains stability and bioavailability in a pH range of 3 to 10. This makes it particularly suitable for diverse agricultural environments, including alkaline soils where iron deficiency is common.

The organic chelation process ensures that iron remains in a form that is easily absorbed by plants, reducing the risk of nutrient lockout. This technology is especially critical for crops such as citrus, grapes, and ornamental plants, which are prone to iron chlorosis in high-pH conditions.

Key Advantages of EDDHA Fe 6%

The EDDHA Fe 6% offers several distinct advantages over conventional iron fertilizers:

• Enhanced Stability: The EDDHA chelating agent ensures iron remains available to plants even in alkaline soils, where traditional fertilizers often fail.
• Improved Solubility: The microgranular formulation prevents clogging in irrigation systems and ensures uniform distribution.
• Environmental Safety: As an organic chelate, it minimizes the risk of heavy metal contamination and is compatible with sustainable farming practices.
• Cost-Effectiveness: Reduced application frequency and increased nutrient uptake lead to long-term savings for farmers.

Applications in Agriculture

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

• Orchards and Vineyards: Prevents iron chlorosis in citrus, grapes, and other fruit-bearing plants.
• Greenhouses and Nurseries: Ensures consistent nutrient supply for ornamental plants and seedlings.
• Vegetable Gardens: Enhances growth and yield in crops like tomatoes, peppers, and leafy greens.
• Lawn and Turf Management: Maintains vibrant green color and healthy growth in lawns, even in challenging soil conditions.

According to NIST's research on agricultural chemical stability, "the development of chelated fertilizers has significantly improved nutrient management in high-pH environments, aligning with the institute's focus on precision in measurement and material science" (NIST, 2025).
