Radiocarbon dating uses the decay of a radioactive isotope of carbon (14C) to measure time
and date objects containing carbon-bearing material. With a half-life of 5,700±30 years …

Organic matter decomposition is a biochemical process with consequences affecting climate
change and ecosystem productivity. Once decomposition begins, C is lost as CO 2 or …

Elucidating the processes underlying the persistence of soil organic matter (SOM) is a
prerequisite for projecting soil carbon feedback to climate change. However, the potential …

The response of the terrestrial carbon cycle to climate change is among the largest
uncertainties affecting future climate change projections,. The feedback between the …

Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling
within and across ecosystems is central to understanding global patterns of key ecosystem …

Soil contains approximately 2344Gt (1 gigaton= 1 billion tonnes) of organic carbon globally
and is the largest terrestrial pool of organic carbon. Small changes in the soil organic carbon …

Boreal forest soils function as a terrestrial net sink in the global carbon cycle. The prevailing
dogma has focused on aboveground plant litter as a principal source of soil organic matter …

The soil is important in sequestering atmospheric CO2 and in emitting trace gases (eg CO2,
CH4 and N2O) that are radiatively active and enhance the 'greenhouse'effect. Land use …

Microorganisms exist throughout the soil profile and those microorganisms living in sub-
surface horizons likely play key roles in nutrient cycling and soil formation. However, the …
