    I disagree with that last slide. I did nothing but change over to no-till for the first few years I was getting into this soil health initiative and that alone along with adding in cereal grain production, brought my SOM levels up by over 1.5% in three years. When I started incorporating cover crops of ~3,000#DM/ac in the off season, I gained another .5% SOM in the first two years. There's a lot more going on in that process than just what is gained from the DM of the cover crop. As Mr. Weil pointed out to start with in the vid, much of SOM is actually from the soil life that is fed and grown by the root mass of the cover crops. It seems that point was completely lost in that last slide. At any rate, my farm and experience has shown differently from that last slide.
