I am new to this site though have been in the business part-time for 7 years. Usually will apply granular and then go back and backpack or tank spray my herbicide. Have serveral in the area that just spray the fert. by adding granular to the tank and mixing. Can some one tell me the trick to this. I would like to add it to my system for one app this year and see if it is a viable option every two or three app's. Can buy liquid at Lesco, but it is very expensive and they tend to not push it. A slow release urea base fertilizer probably will not desolve in the tank. Means I would have to use a fast release with little residual affect. Any comments would be greatly appreciated and I will try to return any help I can.
