Keywords: N deposition, long-term experiments, moisture manipulation and soil warming

Session Description: In the rapidly changing world of the Anthropocene, in situ experimental manipulations are necessary to push soils to novel states for which we have no current analog and to understand the cascading effects of global change factors, such as warming, N deposition, CO2 fertilization, and drought, on soil biogeochemical processes. Long term experiments are especially important for revealing non-linear and threshold-type responses that could not have been predicted from the initial responses. This session seeks to highlight the new insights from existing long term experiments in agronomic and natural systems, and introduce recent soil experiments that have long term aspirations.
