Abstract/Contents: | "The substantial stocks of carbon sequestered in temperate grassland ecosystems are located largely below ground in roots and soil. Organic C in the soil is located in discrete pools, but the characteristics of these pools are still uncertain. Carbon sequestration can be determined directly by measuring changes in C pools, indirectly by using 13C as a tracer, or by simulation modelling. All these methods have their limitations, but long-term estimates rely almost exclusively on modeling. Measured and modeled rates of C sequestration range from 0 to > 8 Mg C ha-1 yr-1. Management practices, climate and elevated CO2 strongly influence C sequestration rates and their influence on future C stocks in grassland soils is considered. Currently there is significant potential to increase C sequestration in temperate grassland systems by changes in management, but climate change and increasing CO2 concentrations in [the] future will also have significant impacts. Global warming may negate any storage stimulated by changed management and elevated CO2, although there is increasing evidence that reverse could be the case." |
