EDTA is a chelate which protects nutrients against precipitation in a moderate pH-range (pH 4 - 6.5). Mainly used for nourishing plants in fertigation systems, and as an ingredient for NPKs. EDTA chelates will not injure leaf tissue, contrarily it is ideal for foliar spraying to nourish the plant. EDTA chelates are produced using a unique patented micro-granulation process. This method guarantees a microgranule that is free flowing, dust-free and caking-free, and easily soluble.
