   Wanted to get some opinions on EDTA in foliar fertilizers. Pros and Cons.....positives and negatives? I have heard not to spray products containing it and others have told me it will help with plant uptake. I am only using this in one micro product and im only spraying it once a month.

   It is my understanding that EDTA chelations last longer than glucoheptonate chelations. For example, if I spray a cheap iron product with glucoheptonate, it will give me an immediate 4-5 days of green, but that's all. If I spray an EDTA chelation, like Sprint 330, it will take 3-5 days to show green, but it will last up to 30 days. That is the extent of what I know, if I'm even correct about it.

   I was incorrect in stating that Sprint 330 was EDTA. It is DTPA. So, I think that Glucoheptonate is the shortest and DTPA is the longest lasting chelation. That would put EDTA in the middle.

   OK, last correction. Next time I'll do my research first, then post.
   
   Strongest = EDTA
   
   2nd Strongest = DTPA
   
   2nd Weakest = Citric Acid
   
   Weakest = Glucoheptonate
   
   My point being, it should give you delayed but prolonged results. I am unaware of any negatives to EDTA.

   At least you did research Kevin, some of us post and do not follow up.

   Thanks....this is what im aiming to achieve...My salesman told me that this(added micro package with iron) would give me color for about 21 days plus with what im doing already i should have a better green look to my greens. I would usually spray my foliars and the green look i want would only last for a few days...with the research i have done and with what you have provided me...looks like i will give this a try. Again thanks for the help!

   I'll give a different take: "Foliar fretilizer" and "long lasting result" don't fit in the same sentence for me. Foliars are for a more immediate effect when absorbed through the leaf tissue and are used to fill gaps in fertilizer applications (such as micros that can be hard to convert and uptake in the soil).
   
   There are lots of great products out there chelated every way immaginable. I would not count on any one of them to fill the gap for my micros once a month. I just dont think you will get enough of the product in you solution and into the plant to last that long.

   Daniel,
   
   In theory, I agree with your statement. I do not know the first thing about chelations, so I will not be suprised if my thoughts are scientifically inaccurate. What I stated is how it was explained to me, and it's what I think I've seen.
   
   With Iron, it appears to have worked that way. If I want a prolonged green with limited growth, the Sprint 330 (PTDA) has been exceptional. If I want short green-up for a tournament, I use varieties of glucophenate derived Iron.
   
   It was explained that EDTA and PTDA have a stronger bond than typical chelates. If I'm not mistaken, chelates help to adjust soil pH, making the Iron more available to the plant. Maybe due to the stronger bond, it's the chelation that's lasting longer in the soil, not necessarily the iron. Perhaps the chelation is utilizing locked up iron already in the soil.
   
   I would love to hear more on this.

   I could be wrong but I believe some of the problem is the use of the word "foliar". To some it means simply spraying...to others it refers to leaf absorbed. Spraying over top and targeting uptake through the roots can provide more of a prolonged effect (if not long lasting) than a product that is primarily leaf absorbed.
