...res carbon," Montgomery said. "If all farms on the planet were converted to no-till, the range of estimates for sequestered carbon runs from 10 percent of current carbon emissions to about half. "It's probably closer to 10 percent, but even that would be a significant benefit," he said. "It's one of the ......first views of Earth from space remind us that the planet is an integrated system of organisms, water, land, and atmosphere.
