Others in the industry are using improved soil management methods to reduce greenhouse gases. That includes no-till farming, where farmers plant crops without using machines to plow or turn over the soil.

The method also keeps carbon in the ground instead of releasing it to build up in the atmosphere as carbon dioxide."
