I'm in the San Joaquin valley. Our soil tends to be alkaline. Well, at the
elementary school, we have a Life Lab (hands on science w/garden plots). I
have a few teachers who want to grow potatoes.
My gardening book says that pototoes need acidic soil but not to use lime.
How else do I get the soil to move to the acidic side? We're about 7.5 to
8.0.

Thanks
Nicole
