This stand of plants you see above is iron and clay cow peas and buckwheat. We seed behind the pigs especially when it is muddy and they till the ground bare. One of the lessons that farming has taught me, that is applicable in more ways than one, is that succession is inevitable. Given the opportunity things will fill the gap where others have just left. It applies from the microbial level all the way up in nature. This bare muddy ground is now covered with green plants. What will be successional in your life if you have the guts to remove something else?
