One afternoon last March, on a small vegetable farm that Paul Kaiser runs in a particularly chilly valley in Sebastopol, California, a group of agriculture specialists gathered around a four-foot steel pole. The experts had come to test the depth and quality of Kaiser’s top-soil, and one of them, a veteran farmer from the Central Valley named Tom Willey, leaned on the pole to push it into the dirt as far as he could.
