Thanks guys

I was afraid that was the problem but not sure. I used the powder form of lime and threw it out from the bank (300 pounds for about 1 1/2 acre), but it didn't always go in the direction I threw it. Now I have a flat bottom boat. What about the granule form of lime?
I wonder if the county coop extension does testing on water. I know what the soil is, red clay with some sandy loam. In some spots gray clay down about 8 - 10 feet. I found one rock on the entire property.
