Soil warming and organic carbon content

Article Abstract:

Issues concerning the carbon content of soils and the rates at which the carbon is transferred into the atmosphere, depending on temperature, is discussed.

Temperature sensitivity of soil carbon decomposition and feedbacks to climate change

Article Abstract:

Significantly more carbon is stored in the world's soils than is present in the atmosphere, however, the effects of climate change on global soil carbon stocks is unclear. The diverse soil organic compounds exhibit a wide range of kinetic properties, which determine the intrinsic temperature sensitivity of their decomposition.

Pasture soils as carbon sink

Article Abstract:

Transplanted African grasses, such as Brachiaria and Andropogon, in South America may reduce atmospheric carbon dioxide through enhancing the soil's carbon storage. However, this effect is likely to reduce over time while it is not significant enough to justify destroying current biomass, such as rainforests, for pasture land. The carbon sink effect is a, possibly temporary, side benefit of grassland that is converted to pasture when African grasses are imported because of better survival rates on poor soil but these grasses are highly flammable and may have a negative impact on the local plants.
