Corn and soy growers take a step back from cover crops, says Purdue survey
Fewer of America's large-scale corn and soybean farmers are planting cover crops this year than last, and nobody says they're doing it to lock carbon in the soil, said a Purdue University survey on Tuesday. Cover crops, long promoted as a way to improve soil health, have more recently been promoted as an agricultural practice that mitigates climate change and could be a new source of income.
