Rolla, ND | The reaction of Glyphosate with inhibitory ions is clearly reversible in solution.
The order of mixing in this case has more to do with the chance that there's going to be problems with say a lump or something with the AMS than that it has to react first with the ions. Ions are by definition free to react or they wouldn't be ions.
Here's the proof: Monsanto now sells their glyphosate largely as the Potassium salt of glyphosate, this is due to the fact they can get more glyphosate into a specific volume of product. Potassium is an ion that inhibits glyphosate, not nearly as much as say calcium but it does inhibit it.
If you go back to the old formula of how much AMS to add to spray water to take care of the Potassium in the water. It required 0.002 mulitplied by the ppm of Potassium to get the lbs per 100 gallons of AMS to add to the water.
If the reaction wasn't reversible, the Monsanto products using the potassium salt would clearly not give as much activity as other products, but through the addition of AMS you effectively turn the glyphosate into the ammonium salt.

Why no AMS in glyphosate
