We're big fans of composting and adding manure to the garden in the autumn, it has really increased our soil fertility. Our neighbor who is a conventional farmer has soil that's pretty well dead, his yields are about half of ours. Here are some examples of healthy soil and what it will produce. Below is the first of our corn harvest. We grow open pollinated corn and grind it for cornmeal; this was not by any means the largest ear, merely the first to ripen!
Aleks also trained the pole beans to climb the corn stalks. The problem now is that the corn stalks are 10-12 feet high and the beans dangle high overhead. :-)
