Had a soil test done, and the lab recommended 5lbs sulfur/100 sq. ft. to lower the pH. Scanning my local Lesco inventory, I see that they have something called DISPER-SUL available. Is this the right product to use? If so, can I also put down an application of 21-0-0, which has a 20% sulfur content, at the same time as a fall fertilizer? Given my lot size, that would pretty much get me my 5lbs sulfur and give me that final shot of N everyone seems to recommend. Thanks.
