In American farm country, a grass-roots movement is spreading, a movement to keep more roots in the soil. (Not just grass roots, of course; roots of all kinds.) Its goal: Promoting healthy soil that's full of life.
I met three different farmers recently who are part of this movement in one way or another. Each of them took me to a field, dug up some dirt, and showed it off like a kind of hidden treasure.
"You can see how beautiful that soil [is]," said Deb Gangwish, in Shelton, Neb. "I'm not a soil scientist, but I love soil!"
