Here’s a sample from Gary Zimmer’s online course, where he is teaching the basics of soil health on his farm:

Acres U.S.A. Intensives put attendees in the field with the instructor to learn with all five of their senses. You will hear practical and useful information, see how it is applied, smell and feel the difference in healthy soil, and finally, taste food grown on the farm and prepared by a local chef. These are premium, life-changing opportunities to experience the change you would like to see on your own farm or ranch.
