These farming techniques can help trap carbon dioxide in the soil and make farmers an extra buck

▤ Summary

For the last five years, farmer Trey Hill has planted year-round cover crops and refrained from tilling the soil. The plants that blanket his fields all year long help to draw in carbon dioxide and lock it into the soil. Hill doesnt turn over his soil every fall after a harvest, which prevents the trapped carbon dioxide from escaping back into the atmosphere. President Joe Bidens administration has also earmarked $30 billion to help pay farmers to implement sustainable practices and capture carbon in their soil. And carbon markets have yet to prove that they can be an effective incentive to get more farmers to adopt the environmentally friendly practices.
