Global Change and Terrestrial Ecosystems Soil Organic Matter Network, Rothamsted Research
Data Center Description
The GCTE SOMNET (Global Change and Terrestrial Ecosystems Soil Organic Matter Network) is administrated at Rothamsted Research.
Soil organic matter (SOM) plays a central role in nutrient (N, P, S, K) availability, soil stability and the flux of trace greenhouse gases between land surface and the atmosphere. It represents a major pool of carbon within the biosphere, estimated at about 1400-1500 x 1015 g globally, roughly two to three times that in atmospheric CO2 and acts as both a source and a sink for carbon and nutrients. To facilitate scientific progress in predicting the effects on SOM of changes in land-use, agricultural practice and climate, the need for a network of SOM modelers and long-term data holders was recognized. To fulfill this scientific need, the global Soil Organic Matter Network (SOMNET) was established during 1995 under one-year's funding as a Special Topic of NERC's TIGER program.
