EDTA diammonium salt fertilizer in EDTA chelated fertilizers
Thread Content
I’m wondering why EDTA diammonium salts are not included in current EDTA chelated fertilizers; their CAS numbers cannot be found either. The fertilizers contain only some trace elements such as calcium, magnesium, zinc, etc. Is it due to a lack of market demand, or is it because EDTA diammonium salts are not suitable as fertilizers? I’ve searched extensively but found no information on this topic. Thank you again to all of you for your help.
Using EDTA as a fertilizer? Something that costs tens of thousands of yuan per ton being used as fertilizer? It would be fine if it were a money-making tree
EDTA is generally used to chelate trace elements, while ammonia is usually provided through urea, *ao acid, sulfuric acid, etc.; cost must be taken into consideration!

The cost of EDTA is quite high, but the amount used in these fertilizers is very small, usually between 0.2% and 3%, so the cost remains acceptable! You should know that the price of many water-soluble fertilizers is tens of thousands of yuan per ton; given that the cost of the EDTA complexes used in them is only a few thousand yuan, the added value is quite high!
