Chemical Property:
EDDHA-Fe 6% is a chemical compound primarily used as an iron chelate in agriculture. Its full name is Ethylenediamine-N, N'-bis (2-hydroxyphenylacetic acid) iron complex. Its CAS number is 16455-61-1.
EDDHA-Fe 6% is a dark red to brownish-red powder that is highly soluble in water. Its key chemical property is its ability to chelate or bind with iron ions (Fe3+) effectively, forming stable complexes. This chelation prevents iron from becoming insoluble in alkaline or calcareous soils, making it readily available for plant uptake.
EDDHA-Fe 6% contains two forms of chelated iron: the ortho-ortho (o-o) isomer and the ortho-para (o-p) isomer. The o-o isomer is highly stable and provides long-lasting iron availability to plants.
EDDHA-Fe 6% has several applications in agriculture and horticulture due to its unique properties:
1. Agriculture: EDDHA-Fe 6% is primarily used as a chelated iron fertilizer in agriculture to address iron deficiency in plants, a condition known as iron chlorosis. Iron deficiency can lead to yellowing of leaves (chlorosis) due to insufficient chlorophyll production. EDDHA-Fe 6% is especially effective in alkaline and calcareous soils, where iron availability is limited.
2. Horticulture: EDDHA-Fe 6% is widely used in horticultural applications, including ornamental plants, fruit trees, and vegetables, to prevent and treat iron deficiency symptoms and enhance plant growth and quality. Iron is an essential micronutrient for plants, and this chelate ensures the availability of iron to plants, even in soils with high pH levels or high calcium content.
3. Greenhouse Cultivation: In greenhouse environments, where precise nutrient management is crucial, EDDHA-Fe 6% is used to maintain optimal iron levels for plants.
4. Soil Amendments: EDDHA-Fe 6% can be applied as a soil amendment to improve the iron availability in soils with limited iron solubility. This ensures that plants have access to the iron they need for healthy growth.
5. Hydroponics and Soilless Cultivation: EDDHA-Fe 6% is also used in hydroponic and soilless cultivation systems, providing a consistent source of chelated iron for plants.
6. Landscape and Turf Management: EDDHA-Fe 6% is used in the maintenance of lawns, parks, and landscapes to prevent and correct iron deficiency issues in plants.
7. Environmental Restoration: In environmental restoration projects where soil quality is a concern, EDDHA-Fe 6% can be used to improve conditions for plant establishment.
8. Foliar Applications: EDDHA-Fe 6% can be applied as a foliar spray to quickly correct iron deficiency symptoms in plants.
9. Nursery Production: EDDHA-Fe 6% is used in nursery settings to produce healthy and vibrant plants for sale.
EDDHA-Fe 6% is valuable in agriculture for its ability to address iron deficiencies in various soil types and pH conditions. Its chelating properties ensure that iron remains accessible to plants, promoting healthy growth and preventing iron-related nutrient deficiencies. Proper application is important to achieve the desired results and improve crop yields and plant health.
