0-0-25 is not pure, solution grade potassium sulfate. You might have to go to an Agrium outlet or another dealer that caters to nursery and greenhouse growers for the potassium nitrate. I like to use 1/2 lb or less of N and 1/2 lb of K per 1000 sq ft per month of growing season.

Unless the turf is irrigated and you can turn the water on immediately after application, minimum application volume is in 5 gallons per 1000. Ride on sprayers will not work. Neither will any kind of boom sprayer with a low output pump. This is one that should be done with a skid sprayer or a boom capable of putting down high volumes.
They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
