THE SECOND PRINCIPLE OF SOIL HEALTH


                 Minimize Soil Disturbance

     As a teenager, I remember coming home from football
     practice, eager to jump in the tractor and run the ripper
     until the wee hours of the night. That was some of the best
     times as a junior high and high schooler, being able to help
     out my dad and run the ripper. I didn’t know that there was
     a different way to have success with the corn on corn we
     were growing. I thought you had to have the seedbed fully
     prepared or else it would seal up over the top and the corn
     wouldn’t be able to come through the crusted-over soil. I
     thought tillage was the answer.

                                                               cycling nutrients and residue for us. Now that we’re a couple

                                                               It wasn’t until we got into cover crops that our no-till sys-
