Soil responses to manipulated precipitation changes: A synthesis of meta-analyses

lt;pgt;In the face of ongoing and projected precipitation changes, precipitation manipulation experiments have produced a wealth of data about the effects of precipitation changes on soils. In response, researchers have undertaken a number of synthetic efforts. Several meta-analyses have been conducted, each revealing new aspects of soil responses to precipitation changes. We synthesize the findings of 16 meta-analyses focused on the effects of decreased and increased precipitation on 42 soil response variables, covering a wide range of soil processes and examining responses of individual variables as well as more integrative responses of carbon and nitrogen cycles.lt;/pgt;
