An increasing number of Iowa Farmers have begun growing cover crops as part of an effort to reduce carbon emissions and fight climate change.
Carbon farming involves growing cover crops, like cereal rye, in alternating rows with crops like soybeans and refraining from tilling fields. These practices increase the level of nutrients in the soil, help prevent erosion, and can help sequester more carbon in the ground.
While carbon farming is not hugely profitable now, many farmers are getting paid to participate in these initiatives. It can help farmers who are currently struggling with low corn and soybean prices reach profitability, and it leaves them with healthier soil and a more sustainable way to farm, according to a Hawk Eye article.
Sequestering carbon in the soil also comes with a number of environmental benefits. The stored carbon in the ground is cut off from contact with the atmosphere where it would combine with oxygen to create carbon dioxide, a greenhouse gas. By reducing erosion, it also improves the health of Iowa’s rivers, lakes, streams and wildlife.
