I am spending a lot of time looking at and thinking about the bison's hoof. Bison are ungulates. Their two toed hooves are a cross between a spade and two chisels. With the weight of their massive bodies their hooves cut into the soil, churn it up, break clumps, and create pockets that hold moisture. They trample old vegetation into the ground a long with the 40 lbs of waste they create everyday. They have a two pronged tools on each leg that tills and cultivates 24/7. And then you put them in a herd and they are mother nature's industrial farmer.
