On a lawn with anything over 7.0, I am also throwing in 5 lb of DF sulfur in addition to the AS and micronutrients. Do not try this on lawns that cannot be irrigated after application.
I was Lazy and Wally World was only one mile up the street. I had looked at fertilizer a few days before and saw a 16-4-8 100% AS and K2SO4. I think it had a 3% Fe also. I was surprise they would carry a Lawn Burner Like that. Of course I have posted about Sulfur application many times. 10 Lb of 0-0-0-90 per thousand lowers pH one point in 30 days. 30 days mean it takes 30 days to release the sulfur.
