This site has a calculator it says it would take 7 pounds of sulfur to lower your pH from 7 to 6.5-6.8.

(That measurement was if your soil was a clay soil.). It would be only 2 pounds for a sandy soil. I am not sure why they would recommend so much, your pH is pretty close to being ideal. Maybe gypsum would be a better way to get some sulfur into the soil without tweaking the pH.

It takes a lot of elemental sulfur to reduce ph. It took me 50 lbs to go from 8.2 to 7.0. That does seem abnormal as mine said to put 4 lbs down. Is the ph from western labs? Is it exactly 7 or are you rounding? The ph scale goes by 10, so 8 is 10 times more basic than 7. I would recommend no more than 10 lbs if it is truly a 7 ph.

Sorry, but, what'll be the point of a soil test if we don't follow the recommendations, verbatim? I think there may be a time frame involved as well, meaning that over the long term, which is NOT gonna be overnight, or I'd be amending my soil this week, too, lol, the result at the end of that time frame will be the result of the actual recommendations. I think you should contact the people you paid money to if you have a question, and then, combined with others' recs here as well, make your decision. 2021 Dimarco in 2021 - yeah.

Hi Paul,mine said add 12 lbs per 1000 square feet.My ph was 7.0. I looked at 5 colorado growers tests and I noticed the the higher the calcium levels the more elemental sulfur they recommended.Elemental sulfur is not sulfate.Ive put in 10 every year for a long time.It gets oxidized into sulfuric acid slowly.
