In this episode I talk with Peter Kellman and Rebekah Yonan about growing your own calorie crops and the systems they use to grow and process their food using a minimum of external inputs. We cover the ins and outs of planting, harvesting, threshing and winnowing serval types of grains and beans as well as managing soil fertility using mostly leaves and urine. Peter talks about the book Farmers of Forty Centuries by F.H. King
