Niklaus (b), Ellen Kandeler (a) Keywords: Climate change; Soil warming; Precipitation; Soil moisture; Soil respiration; Arable soil Abstract: a* We present one of the first climate change experiments in an agricultural ecosystem. a* The HoCC experiment combines soil warming and altered precipitation. a* Water limitation reduced microbial biomass and soil respiration in the first summer. a* Soil warming increased soil respiration in the second year by 27%. a* Moisture regime of soils largely determines their function as C sources or C sinks.
