Responses of terrestrial nitrogen pools and dynamics to different patterns of freeze‐thaw cycle: A meta‐analysis
Abstract Altered freeze‐thaw cycle ( FTC ) patterns due to global climate change may affect nitrogen (N) cycling in terrestrial ecosystems. However, the general responses of soil N pools and fluxes to different FTC patterns are still poorly understood. Here, we compiled data of 1519 observations fro...

Abstract Altered freeze‐thaw cycle ( FTC ) patterns due to global climate change may affect nitrogen (N) cycling in terrestrial ecosystems.

Results showed that under FTC treatment, soil NH 4 + , NO 3 − , NO 3 − leaching, and N 2 O emission significantly increased by 18.5%, 18.3%, 66.9%, and 144.9%, respectively; and soil total N ( TN ) and microbial biomass N ( MBN ) significantly decreased by 26.2% and 4.7%, respectively; while net N mineralization or nitrification rates did not change.
