I like 14-0-46 (Potassium Nitrate) and 0-0-21(Ammonium Sulfate) and dissolve both in a 5-gallon bucket of slurry with warm water and also fill the tank with water and about 4 oz of vinegar the night before so it can warm up also.

With a soil pH over 9.5 on most of my accounts I actually use more Potassium Sulfate and Ammonium Sulfate than any other forms. Look to minors Like MG to help with fungus issues. Some minors have drying effects on some fungi.

One reason I might not have trouble mixing is my calibration of 5 gallons per thousand of finish spray. I know that is old school but it works for me.


it is one thing to do a off label applications. It is total stupidity to post it on the world wide web and expect people to approve.
