A Gardeners Forum Forums General Discussion The Food Garden Forum I need to lower my PH by 1+p....

so I'm now looking for a good sourse of ground rock sulfer. I have plenty of 10-0-0 in the barn that I can use but that's only about 20% (that's going the "long way" to get there) I think?

Thank you.

ooops..make that 21-0-0 NOT 10-0-0. Sorry

Exactly what is your soil Ph? How low do you want it, and what crop in particular do you want it lowered for?
I can give you many options if I knew.

It is 7.3 now and want to bring it to around 6.3 + - Some of the Sulfates are expensive, just looking for some savings if I can.

Hmmm...just cruised in and saw you'd posted, spearo. I can know the full chemistry/mechanics of it, but that 21-0-0 with 20% sulfur will make a big difference, esp depending on what your soil is like...sandy, loamy, clay or whatever. Gear your crops this year to alkaline tolerant or neutral plants, start working in lots of oak leaf litter or pecan, etc. I have to lower soil pH in one garden bed I have that is 7.1, I'll be growing tomatoes in it and need it below 7 preferably. I'm using garden sulfur in 4 lb bags plus shredded leaves, compost, mannure...
get the loam content up, and you won't need to worry about exact pH as much. Some peat would help, but not as much immediately as sulfur, and peat is pricey, too.
Hope this helps, post more about what's available and what you plan to grow. Tomatoes, peppers, and many things can be grown in containers, might consider that.
