Our soil is poor and FULL of shale, quartz, you name it. We grow rocks, I guess. The corn and soybeans seem to grow okay on the fields, and many areas have very rich soil (especially where the erosion deposits are). But the corn fields almost look as if I mulched them with rocks! Sometimes I dream about a big barrel made of metal mesh, scooping big hunks of dirt in there, screening out the rocks, and having soil with NO ROCKS! I actually wish I could have big piles of stuff - coarse sand, manure and SCREENED dirt, wood chips, whatever - and that I could make soil! I know I will do this eventually over time with soil enhancements, but it just seems like somebody has to have make some kind of soil sifter thing to get rid of the rocks!
