This article talks about soil’s ability to sequester carbon and at the rate it can do so. The carbon in the biomass of plants get integrated into the soil when the plant dies and decomposes. With computer programs it was estimated that the carbon in the soil is 450 years old meaning it sequesters it at a relatively fast rate; however, recent studies with actual soil samples has proven the carbon in the soil to be at least six times as old as previously thought. This is quite abrupt news because we can no longer count on the soil to help sequester as much carbon as we were before. With global CO2 levels on the continuous rise it seems we need to start brainstorming ways to continue lowering our CO2 emissions as well as ways to sequester the carbon already in our atmosphere.
