| 英文摘要 | Warming significantly alters the soil organic matter cycling processes, so does biochar addition to soil. How they interact to influence soil organic matter (SOM) cycling has received little attention. This study aims to fill this knowledge gap. A sandy-loam Aridisol amended with corncob-derived biochar at 1 or 5% (w/w basis) was incubated at 20 degrees C as well as 30 degrees C (warming). Soil respiration, priming effect, as well as a suite of soil variables were measured. Soil respiration increased by 12.4% and 21.2% at higher and lower biochar addition indicating that adding biochar at higher rates would increase soil (C) content by concurrently increasing the C input and altering the C: N ratio resulting in limited nitrate availability. Moreover, biochar addition at 1% reduced the overall temperature sensitivity (Q10) of soil respiration whereas 5% BC addition didn't change it. In addition, biochar addition at both rates induced significant negative priming effect irrespective of warming thereby further confirming the biochar's potential to stabilize C in this soil. Biochar mitigated the deleterious effect of warming on microbial biomass linearly with respect to addition rate. Warming significantly decreased chitinase as well as alkaline phosphatase activities. The warming induced reduction in activities of these enzymes was mitigated by biochar addition in a linear fashion, though their activities remained lower compared to biochar amended room-temperature soils. Overall, our study demonstrated that biochar amendment significantly modulated the effects of warming on soil's biochemical processes. Biochar amendment enhanced soil resilience by stabilizing C cycling and extracellular enzymatic activity, highlighting biochar's potential to mitigate the impacts of warming on soil. |
