Ran across this book "tree Crops: A Permanent Agriculture" by J Russel Smith. It was originally published in 1929. They
sell on copyrighted in 1953 at Amazon for about 56 bucks. I was just about to buy it, when I found it in a PDF format for free.
Tree Crops: PDF (will take a while to down load)
The book advocates no till with tree crops on the slopes and pasture on the flat spots. It talks to the dust bowl days and laments on the huge erosion problem in the US. He lists specific
trees and their uses. Does anyone know if you can put PDF docs on a Kindle? This could be my excuse to get one.
