• Most farming is intended to produce something that’s harvested from the land. Carbon farming is the opposite. It uses plants to trap CO2, then strategically uses practices such as reducing tilling, planting longer rooted crops and incorporating organic materials into the soil to encourage the trapped carbon to move into and stay in the soil.
• Another way to enhance plants’ ability to store carbon is to partly burn materials such as logging slash or crop waste to make a carbon-rich, slow-to-decompose substance known as biochar, which can then be buried or spread on farmland. Biochar has been used for centuries to enrich soil for farming, but of late has been drawing increased attention for its ability to sequester carbon.
• Plants and plant like organisms that live in the ocean absorb immeasurable amounts of CO2 each year, their ability to do so limited only by the availability of iron, nitrogen and other nutrients they need to grow and multiply. So researchers are looking at strategies for fertilizing the ocean or bringing nutrients up from the depths to hyperdrive plants’ ability to trap and store carbon.
