Climate change can affect soil properties, but studying how elevated CO2 and temperature impact soil from different crop systems can help us understand the effects. The researchers found that elevated CO2 and temperature decreased soil organic carbon and nitrogen but increased soil nitrate levels. The microbial community in the soil changed with climate effects, affecting species richness and structure. Greenhouse gas fluxes were higher with elevated CO2 and temperature, but intercrops showed similar fluxes to ambient conditions. Overall, intercrops did not have an advantage over sole crops in coping with climate effects on soil properties, but greenhouse gas fluxes were similar between different conditions.
