Softened Water used for Herbicide Application (06/23/16)

AMS in Holding Tanks (06/23/16)

Question: A question about dry AMS. I have a large grower that is going back to dry AMS vs a commercial liquid product. Is there any problem if he pre-mixes his AMS in his holding tanks at the correct rates needed for the farm? There could be times when the 4000 gal tanks sit full for 5 days or more if a large rain event occurs, etc. All my other guys mix the dry as they spray by the tank load, but he needs to pre-mix it in his holding tanks if possible due to the size of his operation and to speed up the spraying process. He will be inducting the AMS thru a cone into the large holding tanks, so he should get a good mix.
