Carbon dioxide is the primary greenhouse gas. The concentration of atmospheric carbon dioxide has increased in recent years, causing a stronger greenhouse effect and global warming. Carbon is stored in the atmosphere, vegetation, animals and in soil. Of all carbon reservoirs, soil is the largest pool, holding more carbon than the other three reservoirs combined. There is an opportunity to mitigate climate change through improved agricultural practices in order to store more carbon in the soil. The carbon content of the soil can be raised by increasing carbon inputs, decreasing emissions, or a combination of both.
