Lowering Soil ph
Can someone tell me approximately how much sulfur/acre I'll need to lower my soil's ph from 8.0 to 7?

I thought you'd use lime for that. I don't think I've heard of using sulphur before.

Yeah, I've always used lime. From my experience on my lawn, you have to use a HUGE amount of peletized lime to make a small change in the ph. I did before and after ph readings and the change with one moderate application was negligable.

I have a lot of pine tress around my house, so I apply lime a couple times a year, but have never actually measured the ph. The grass looks pretty good, so I guess I'm getting close enough.

Lime will raise the ph

Doh! Higher Ph means lower acidity. That's what I was thinking only I had the scale backwards, too. The pine tress in my yard (Oaks, too, I think) increase the acidity. Therefore, I apply lime to LOWER the acidity. I guess I've never had the other problem.

Yep, It tested way high at 8-8.2 which makes it tough to grow any grass.
I need to work on lowering it or find a grass tolerant of the high ph. |

Send these guys an email to get an answer no one here will be able to provide because they aren't familiar with the particularities of the soil makeup in Grayson County, TX :http://county-tx.tamu.edu/

Lowering (or raising) pH is more complicated than a simply #'s/acre ratio. The amount depends on soil type. If you have a very sandy soil it will take less. If you have a very high organic content it will take more.
Sulfur will lower pH. Get it with iron or aluminum (iron or aluminum sulfide). I don't know what it costs in TX to get a complete soil analysis, but I doubt it's more than $15-$20 per sample. Scrape away ground cover and scoop soil from the surface down to about 6-8 inches. Mix it thoroughly in a plastic bag. Put a plastic label inside the bag and also label the baggie (or box) that you package the soil in. Call your local NRCS office (blue pages in phone book) and get the address to send the soil.

I certianly don't want to buy too much. I was qouted, as of today, ammoniun sulfate $375/ton.
I might be better off hauling in new topsoil. |

It also depends on what you are growing. If you are growing a cash crop or livestock then you will have to put the fertilizer cost into the overhead. If you're growing a lawn then it's an aesthetic and the value is up to you.

What Bot said.
In the northeast we almost always have acidic soils although every now and then an alkaline one pops up in a soil test. Without a test you're just stabbing in the dark as to how much sulfur to apply. Customers always want to know how far a 50 lb. bag of lime will go and are confused when I tell them anywhere from 250 sq.ft. to 5000 depending on your soil conditions and whether or not your trying to change pH or just maintain it. Amount of sulfur vs. pH is the same. A soil test will take all of the guesswork out of it for you and makes it well worth the $10-25 it'll cost you.
