EDDHA, abbreviation for ethylenediamine-N, N’-bis (2-hydroxyphenylacetic), is a chelate that protects nutrients from precipitation in the highest pH range (pH 4 – 9). EDDHA chelates are therefore suitable for alkaline and calcareous soils as well as soils with a high carbonate content.
They are mainly used for fertigation in the open field and the injection of soil. After dilution, they are suitable for all irrigation systems: drip, micro-jet and any localized injection system. Oligo Premium Iron EDDHA 6% can be used at any stage of the vegetative cycle.
Protection of micronutrients against precipitation in a moderate pH range (pH: 4-9)
High ortho isomer content: 4.2% ortho – ortho.
Water solubility easy and fast.
Suitable for fertigation in the field and injection into the soil. Also suitable for fertigation of high tech off-ground crops
Compatible with most water soluble fertilizers
Iron is essential for the enzymatic system and plant metabolism (photosynthesis and respiration). The enzymes involved include catalase, peroxidase, cytochrome oxidase and other cytochromes. In addition, it is part of the ferredoxin and is necessary for the reduction of nitrate and sulfate, and essential for the synthesis and maintenance of chlorophyll in plants. Iron is strongly associated with protein metabolism.
