Unlocking the Challenge of Soil Iron Deficiency: EDDHA Fe 6% Chelated Iron for plants, the Professional Choice for Powerful Restoration
Are you facing this dilemma: widespread yellowing of new leaves, while veins remain green, overall growth stagnation, and little effect from supplemental fertilization? This is likely not just a case of ordinary malnutrition, but rather iron-deficiency chlorosis caused by “ineffective iron” in the soil.
Today, we’ll introduce EDDHA Fe 6% Chelated Iron Fertilizer, recognized in the agricultural technology field as the ultimate solution for severe iron deficiency chlorosis.

What is EDDHA Fe 6% Chelated Iron for plants? It’s not just any iron fertilizer.
Simply put, EDDHA Fe 6% is a molecular-level, highly effective trace element fertilizer. Its core lies in “chelation” technology—it’s like equipping iron ions (Fe) with a sturdy “bulletproof vest” and “dedicated navigation,” enabling them to withstand the harsh soil environment and be precisely absorbed and utilized by crop roots.
EDDHA is currently recognized worldwide as the most stable and effective iron chelator, particularly suitable for alkaline (high pH) soils.
Fe 6%: Represents the iron content in the product, which is the foundation for ensuring fertilizer effectiveness.
Distinctive reddish-brown crystals/granules: This is the most intuitive sign of authenticity for EDDHA chelated iron. Its color comes from its powerful chelating structure, which dissolves instantly in water, resulting in a wine-red solution.

Why is EDDHA Fe 6% an “expert” in correcting iron deficiency chlorosis?
Other iron fertilizers (such as ferrous sulfate) are easily fixed upon application to the soil, converting to a form that crops cannot absorb, ultimately rendering them ineffective. EDDHA Fe 6% offers revolutionary advantages:
a. Unparalleled Stability
In calcareous, alkaline soils with a high pH (7.5-9.0), conventional iron fertilizers lose their effectiveness almost instantly. EDDHA chelated iron, however, remains stable for months in these harsh environments, continuously providing iron to crops. This is something other types of chelated iron (such as EDTA) cannot achieve.
b. Extremely High Absorption Efficiency
Its unique molecular structure is recognized as a “friendly substance” by crop roots, allowing for extremely rapid absorption and transport. New leaves can begin to turn green in as little as 3-5 days after application, offering rapid results.
c. Double Activity: Ortho-Ortho Isomers
High-quality EDDHA iron fertilizers in the industry will indicate the “ortho-ortho” isomer content (typically ≥4.8%). This is the most biologically active form of the EDDHA molecule, making it the most readily absorbed by plants. This ratio directly determines the product’s ultimate effectiveness and price. Our products utilize a high ratio of active isomers, ensuring exceptional value for every investment.

Product Key Features and Usage Guide
a. Appearance:
Reddish-brown powder/crystals with excellent fluidity, easy to weigh and dissolve.
b. Iron Content:
≥6.0% (as Fe)
c. Active Isomer Content:
A high proportion of ortho-ortho isomers ensures optimal absorption efficiency. (You can enter your specific data here, e.g., ≥4.8%)
d. pH Range:
Extremely wide (3.0-11.0), designed for challenging conditions, especially alkaline soils.
e. Usage:
Root irrigation/drip irrigation: The preferred method. Use approximately 100-200 grams per mu (approximately 1.5-1.7 acres). Dilute and apply with water or through a drip irrigation system. Direct application to the roots for long-lasting results.
f. Foliar Spray:
Dilute 3000-5000 times and spray on both sides of new leaves. Can be used as a rapid regreening aid.
g. Applicable Crops:
Widely used for all high-value, iron-sensitive cash crops, such as:
h. Fruit Trees:
Citrus, apple, peach, pear, grape, kiwi, etc.
i. Cash Crops:
Soybeans, peanuts, strawberries, tomatoes, cucumbers.
j. Ornamental Plants:
Azalea, gardenia, jasmine, lawn, etc.

How to Choose a Genuine EDDHA Iron Fertilizer?
Color: Authentic EDDHA is dark reddish-brown, and the solution is wine-red. Pale or dark color suggests inferior quality.
Smell: Slightly phenolic odor (non-irritating).
Dissolution Test: Dissolves quickly and completely in room temperature water, leaving no residue.
Check Labeling: Ensure the product label clearly indicates the total iron content and ortho-ortho isomer content, as the latter is crucial to its effectiveness.
In summary, EDDHA Fe 6% chelated iron represents a precise, efficient, and reliable plant nutrition solution. It is not a simple fertilizer, but a specialized weapon for addressing specific soil challenges. When your crops face stubborn yellowing challenges, choosing it means choosing scientifically proven, reliable results.
