Im calling about a soil sample so good idea. I also put in a email to the Ag dept a few moments ago. Im just curious because my wife has a pesticide license ( she is an entomologist) and she said that there is not one for herbicides. Of course she could be wrong. I also looked up and saw you DO need a license for fertilizer distribution. I'll ask about clarification on that.
And for the record Im not trying to argue anything, just trying to figure this out.
