| dc.description.abstract | The issue of global climate change raises a need for information on the
management and mitigation of atmospheric carbon dioxide (CO2). The knowledge of
carbon (C) characteristics within land resources can be useful for resource managers and
policy makers to make informed management decisions. Depending on land use and
management, prairie soils can be considered either a source or a sink for atmospheric CO2.
Soil sample cores were taken from seven different regions in the north central U.S. Over
1300 samples were analyzed to determine relationships between grassland age and soil
organic carbon (SOC) levels.
Sample matrices were built to compare restored grassland age classes to adjacent
native grasslands and cultivated croplands in the different study regions. The samples were
taken at 0-15 cm and 15-30 cm increments and were analyzed for organic carbon, inorganic
carbon, and total carbon. Each region was analyzed using regression analysis to calculate
SOC sequestration rates for restored grasslands over time. Restored grassland SOC
sequestration rates were found to be highly variable throughout the region ranging from
annual losses to annual gains of 0.59 ± 1.81 kg m-2 30 cm-1 with an overall sequestration
rate of 0.09 ± 1.92 kg m-2 30 cm- 1
• Overall, as average annual temperature and precipitation
increased, SOC levels also increased. Under proper management restored grasslands in the
north central Great Plains can be managed and used to store atmospheric CO2. | en_US |
