  • Elemental Sulfur

    Created by Linda Rivers on

    My extension office recommended that I use Elemental Sulfur to lower the pH level in my soil just 1 point. I have a 25 lb. bag of compost which I want to use to top-dress my garden. It now has a pH of 7.3 and I would like to move it down to about 6.5. The bag covers 125 square feet of ground with a 1″ top-dress. How much Elemental Sulfur should I add to the bag in order to lower the pH to 6.5? My product is completely organic and your site says that this product is organic too.

    Many thanks, and I love your web site.

    Hello Linda!

    Ten pounds of Elemental Sulfur covers 1.000 square feet of soil so you would need to broadcast 1.25 pounds of it in order to lower your pH one point. Plants thrive in pH conditions between 6.0 and 7.0 but, the best would be 6.5 so, don’t worry too much if you get to 6.3 instead. If you do want to be more precise, just add a slightly smaller amount to compensate for the difference. I would suggest broadcasting the sulfur and then working it into the soil rather than mixing it with compost. The results are much more consistent and it is also recommended by Montana Sulfur Company (the manufacturer).
