Palestine Illinois | I need help with zinc. You can buy 10 pounds of zinc sulfate white mono-hydrate or 0.5 gallons of 9% citric 100 %chelated for the same price.
With the zinc sulfate you get 3.5 pounds of Zn and 1.8 Pounds S.
With the 9% you get 0.5 pounds Zn.
The Zinc sulfate would be broadcast with our dry fertilizer. The 9% would go is our 2X2, mixed with 28% and thiosulfate.
What is the better option???
Thanks Kurt |

Coldwater, Michigan | Well that is in interesting question. If you are going to go dry, Zinc Sulfate is the right way to go. Rather see it banded than broadcast because of the expense of it, and the amount of material it will take to do you any good.
Liquid, since there is no Phosphorous to tie it up, I think the Citric 9% can be an acceptable choice. 2" x 2" should be good placement for it. If there was "P" in the trench with it, then EDTA would be a better choice for chelating agent.

Palestine Illinois | I think I am not totally clear on what I asked. From the notes I have I assumed citric chelated edta were the same thing? After a google I see that EDTA is an acid that does the chelating. So now I have another question... Is edta or citric chelated better. Or does it only matter if you have phosphorous in the solution.
Thank

20 Miles West of Indianapolis Indiana | So zink and 10-34-0 should not be mixed? |
|

Coldwater, Michigan | Kurt,
As to which one is best, that depends on what you are wanting to do with it. For instance: if you were to put the Citric chelation in a Phosphorous fertilizer, a certain amount of it would be tied up by the Phos and made unavaialble. The EDTA is completely chelated and would not be tied up by the "P".
If putting it in with your 28% where you don't have any "P" in the mix, then the citric would probably be just fine. Would work the same in water.

Coldwater, Michigan | Zinc EDTA, and some other chelating agents work fine in 10-34-0. However, some of them start to tie up within about 15 minutes of when they are mixed so are not good chelator if mixing with 10-34-0, or any "P".

Minnesota/Kentucky fertility based on ENERGY | We've mixed citric chelates sulfates with P and it does work, but the EDTA will mix with anything, my concerns is back to if Glyphosate chelates (and its is a chelator) why put down another chelator?
We use sulfate based and its a much better choice from a plant stand point since the plant doesn't read the book |

sw MN | My old tissue tests prove that it ties up, . I have since been using zinc sulfate with good tissue test results. |

Coldwater, Michigan | Concerning Chelates and Glyphosate, the only metal by label that Monsanto allows mixed with Glyphosate is a EDTA chelated Metal such as Zinc, Mn, Mg, Fe, and others. Be sure to note that is the only Chelate they Label. In this instance Monsanto is in the weed control business, and the only form of the metals they are confortable mixing with that Round Up is the EDTA Chelated ones. If not in that form, then they are concerned about affecting weed control.

Coldwater, Michigan | I don't doubt that at all. If only some people knew what they were looking for, and got that from their Ag Retailers instead of what some of them have to sell. That is not meant to be a condemnation of all retailers, just the few that buy cheap micros and sell them for good micros.

Audubon,Iowa | some times cheap inputs create very expensive outcomes on many levels ! junk in junk out! |

Minnesota/Kentucky fertility based on ENERGY | I really get concerned when manufactures start quoting Monsanto, considering one of Iowa best crop scouts from Western Iowa, tested weather Max and his sample had Manganese in there formula so I think we need to look at what the plant wants not what we want. |

|
| |
|
Audubon,Iowa | so does this mean you are willing to tell Monsanto what their product will mix with? |
|
| |
|
Martinsville, Ohio | That question doesn't even make sense to me. Either you do it your way or their way.

|
Audubon,Iowa | but if you do it your way then any product liability is now yours i am willing to bet if you tell monsanto you did something off their ladle they might have due cause to turn their back on you if something goes wrong... if not take legal action on you them selves |

| Am a little late to this conversation… I want to add zinc to 10-34 phosphate fertilizer in furrow with corn. The only chelated form I have been able to find is an EDTA granular, 14%, which I would have to dissolve in the 10-34. Should add, I'm working with a farm in Eastern Europe and can't get any zinc sulfate, which would likely have been my first choice.
As I understand things, EDTA would be the best (or only) chelated form that would be suitable for application with 10-34. Not sure if all EDTA's are created equal… don't want to waste the money if the zinc will be tied up by the phos. Thoughts? Also - what about rates? Was thinking 1 - 1 ½ lb/acre in a moderately deficient soil test. Enough? |

Coldwater, Michigan | Ryan,
True EDTA is fully Chelated and would not tie up with the "P". The issue you get into is some manufacturers combine the EDTA with other Chelating agents. That way you have staged availability, some now, some later. With EDTA that isn't needed because the metal is available to the growing crop, yet not able to tie up with the "P". Some of the other Chelating agents start tying up with "P" within as little as 15 minutes in the presence of "P", and that forms insoluble compounds.
If the dry compound is EDTA agent only, then it should be fine to use for your purpose. I might mix the dry with some water before adding it to 10-34-0.

| Bill, Thanks a lot… Far as I know, it is strictly EDTA so am going to proceed that way. We did a test of mixing straight with 10-34 but had also come to the conclusion it would likely be better to mix with water first. Any thoughts on rates? I was planning on 1 - 1.5 lb per acre of product (14%). Our soils generally show up as low - very low in soil tests. |

South West UK | I routinely use a corn starter fertliser that contains DAP, Sulphur, Zinc, Manganese, Copper, Boron and Iron with all the trace elements from wolftrax.
I don't understand why you would want to mix anything with glyphosate. Don't do it. Glyphosate has enough problems with the salts in plain water, adding more will not help the issue.
Keep it simple, I get the feeling that the trade over there are forever trying to flog you some kind of new fangled fertiliser for you to try. Plants themselves are tougher than we give credit for, and are able to extract elements most of the time except when trying to grow very quickly and there is some kind of imbalance, in which case you can apply a foliar product which is dirt cheap.
I am routinely doing 4 or 5 or even 7 way tank mixes where a crop needs fungicide, growth regulators and foliar feed products. This is routine stuff. |

Coldwater, Michigan | In this area EDTA Zinc Chelates normally run around 9-10%. If you watered your 14% back to 9 or 10% prior to mixing with the 10-34-0 and the 10-34-0 is to be put in the seed furrow, then 1 quart per acre would be excellent, maybe 1 1/2 quarts for a severe deficiency. |

Zinc Sulfate vs 9% edta
