In an attempt to slow the increase in atmospheric CO2 enrichment, researchers are looking at the capacity of world soils to sequester carbon (C) and mitigate global climate change (GCC). Analyses of U.S. turfgrass soils throughout diverse ecoregions indicated that home lawns sequester soil organic carbon (SOC). Rates of SOC sequestration to 15 cm depth ranged from 0.01% yr-1 to 0.70% yr-1 with the majority of lawns sequestering SOC to concentrations of 2-3%.
