I have found a promising solution to the runoff problem. Our homestead is a narrow 10 acre strip between 2 hayfields, one of which does get sprayed. I am going to build tall (hopefully >10 feet) hugel beds along the perimeter. This will stop runoff, buffer highway noise, add to useable surface area, and stop overspray carried by wind. Still not gonna go after the certification, though.
