Introduction: Researchers from German Centre for Integrative Biodiversity Research investigated the impact of climate change and land use on multiple soil functions, utilizing both observational and experimental data. The research assessd whether results from manipulative field experiments align with observed trends in climate, land use, and soil multifunctionality across Europe, which involved measuring seven ecosystem functions, such as microbil respiration, microbial biomass, etc.

Key findings: The observational data revealed a Europe-wide decline in soil multifunctionality associated with rising temperatures and dry conditions, and such decline was exacerbated by cropland management. The experimental data supported these findings, indicating that climate-induced changes will likely reduce soil multifunctionality in croplands and grasslands. The conversion of grasslands to croplands was identified as a threat to soil system integrity. The study emphasized the importance of enhancing soil multifunctionality in arable systems to preserve soil functions amid changing climate conditions.
