Farmer Rick Clifton drives a spray tractor across one of his fields, applying herbicide to cover crops that occupied the ground during fall and winter in Orient, Ohio, on April 5, 2021. Clifton grows cereal rye and rapeseed to prevent erosion and make the ground healthier for his corn, soybean and wheat cash crops. Cover crops store carbon in the soil, keeping the greenhouse gas out of the atmosphere. John Flesher/AP Photo
