Jimmy Emmons has all sorts of things growing in his fields in Leedey, Oklahoma. There’s peas, beans, millets and varieties of grain sorghum, but none of it is for harvest.
He’s growing what’s known as cover crops — plants meant to cover the ground and preserve it. Over the past seven years, he says he’s watched the difference in the soil. He’s often carrying a shovel on his fields, looking and even smelling the dirt.
“Smells real earthy and sweet,” Emmons says.
