Looks like I'm the first to comment here. I'm am wondering how many people who watched this or attended Groundswell, were a little out of their depth when it came to understanding the whole talk. As an electrical engineer, I found it very easy to understand, because all the processes involved are based on simple physical processes, and there are not that many when talking about a car, or a fuel, or energy. Where I get lost is trying to comprehend how you farmers can navigate through the dynamic world of nutrients, weather, weeds, living soil dynamics, crop timing, disease, livestock , etc, etc, etc. Hats off to you all.
