Do the respiration pulses induced by drying–rewetting matter for the soil–atmosphere carbon balance?
Johannes Rousk, Albert C. Brangarí
Abstract
We show that the explosive microbial and biogeochemical dynamics triggered by rewetting dry soil in laboratory experiments also has relevance in intact ecosystems. This highlights an opportunity to use predictions derived from laboratory studies to provide targets in ecosystem-scale biogeochemical studies.
