EDDA iron chelate, commonly known as EDDHA, is a water-soluble chelated iron fertilizer derived from ferric ethylenediamine di(o-hydroxyphenylacetic acid). Its unique ability to maintain iron availability in soil solutions even at extreme pH levels has made it a popular choice for a variety of agricultural applications.
What is EDDHA Iron Chelate?
EDDA iron chelate is a highly effective iron fertilizer chelated with ethylenediamine di(o-hydroxyphenylacetic acid). This chelate provides a stable and bioavailable form of iron, which is crucial for the growth and development of plants. EDDHA iron chelate has a broad pH compatibility range, ranging from 4.5 to 9.0, making it suitable for use in various soil types and environmental conditions.
Benefits of Using EDDHA Iron Chelate
-
Enhanced Growth: EDDHA iron chelate promotes increased plant growth by providing essential iron to the plant, supporting healthy foliage, and enhancing overall plant vigor.
-
Improved Yields: By maintaining optimal iron levels, EDDHA iron chelate helps increase crop yields, particularly in challenging soils with high pH and calcareous content.
-
pH Adaptability: EDDHA iron chelate is versatile and can be applied in a wide range of pH levels, making it suitable for use in both acidic and alkaline soils.
-
Reduced Leaching: The chelated form of iron is less likely to leach out of the soil, ensuring that iron is available to plants throughout the growing season.
-
Organic Option: EDDHA iron chelate is a biodegradable chelate derived from natural ingredients, making it a environmentally friendly alternative to synthetic fertilizers.
Applications of EDDHA Iron Chelate
EDDDHA iron chelate is used in various agricultural applications, including:
-
Foliar Application: Spraying EDDHA iron chelate onto the leaves can provide immediate access to iron for plants, especially during dry spells or when pH levels are above optimal levels.
-
Soil Drench: Applying EDDHA iron chelate as a soil drench can help correct iron deficiencies in the soil, providing long-term iron availability to plants.
-
Fertigation: EDDHA iron chelate can be mixed with water and applied as a fertilizer solution during irrigation to provide iron to the soil and roots.
-
High-Tech Hydroponics: In high-tech hydroponic systems, EDDHA iron chelate is used to provide a stable source of iron for plant growth in nutrient-rich solutions.
Safety and Precautions
使用EDDA铁螯合物时，需要注意以下几点：
-
Avoid Contact with Living Plants: Keep fertilizers and soil amendments away from living plants to avoid potential phytotoxicity.
-
Proper Mixing: Always mix EDDHA铁螯合物 well before applying to ensure the ferrous iron is converted to the chelated form.
-
Right Time of Year: Applying EDDHA iron螯合物 at the right time can maximize its effectiveness, typically in the early growing season before the plant flush.
-
Soil pH Examination: Check soil pH levels to determine if EDDHA铁螯合物 is necessary and to ensure correct application rates.
