Like methane burps, it's possible to curb this source of emissions. Since wet conditions foster methane, separating out manure solids and drying them can cut back on this greenhouse gas. Feedlot managers can also compost the manure in aerobic piles, or send it to an anaerobic digester, in which the methane from decomposing manure is captured for fuel. In California, the state's Climate Smart Agriculture program has awarded grants to 17 dairies to change their poo practices. At one dairy, the manager proposed to separate solids, compost them, and spread the compost on the pasture—that way they were nurturing the ranch grasses, too. In total these projects are estimated to cut 367,467 metric tons of CO2-equivalent emissions over five years, which is about the same impact as taking 16,000 cars off the road.
