   EDTA Micro Nutrient Fe 

EDTA Chelate Fe Trace Element Fertilizer
Shanghai Bi Jun Biotech Co.,Ltd, a leading manufacturer in the chelated micro nutrients market.  
We offer a full range of chelated and non-chelated trace elements, in solid and liquid form. Our solid EDTAs are produced using a unique patented micro-granulation process. The result is a homogeneous, dust-free, free flowing strawberry-shaped product which dissolves easily. We use the same process for our compounds and for our unique biodegradable EDDHA chelates . EDDHA and DTPA are also available as iron chelates. The compounds can be ordered tailor-made and can contain a mixture of different chelates and sulphates in each microgranule.
EDTA is a chelate tech which protects nutrients against precipitation in a moderate pH Range  
(pH 4 - 6.5). Mainly used for nourishing plants in fertigation systems, it works as an ingredient for NPK.  
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 micro-granulation process. This method guarantees a micro granule that is free flowing, dust-free and caking-free, and easily soluble.
