Agroscope Climate Data Incorporated in the National Inventory
Long-term soil-carbon measurement series round out a detailed MétéoSuisse publication on the main climate-observation parameters in Switzerland.
Soil is considered to be an important carbon reservoir. This parameter has recently been incorporated in the national inventory of the main Swiss climate-observation measurement series. Together with experts from the Research Institute of Organic Agriculture (FiBL), the Swiss Federal Institute for Forest, Snow and Landscape Research WSL and the FOEN, Agroscope specialists have compiled the different long-term soil-carbon measurement series for Switzerland and presented them in Chapter 3.12 (‘Soil Carbon’). The complete MétéoSuisse publication is available at the following link (in English only):
Agricultural management is an important control of the soil’s carbon content and hence of the soil’s role as a source or sink of CO2. Crop rotation and management intensity regulate the amount of organic matter entering the soil; this is mainly due to crop residue that remains on the field following harvest. On the other hand, removal of soil C occurs through the decomposition of soil organic matter which is influenced by management via, for example, soil tillage, drainage, or fertilization. Besides its control of C input and output pathways, agriculture also determines the overall area under management and is therefore an indirect factor determining emissions associated with landuse change.
