W., Biasi, C., Wei, B., Zhang, D., Wang, J., Yu, J., Li, F., Wang, G., Kou, D., and Liu, F.: Phosphorus regulates ecosystem carbon dynamics after permafrost thaw, EGU General Assembly 2021, online, 19–, EGU21-376,, 2020. Add open access links from to the list of external document links (if available). These two lines of evidence highlight the crucial role of soil P availability in altering the trajectory of permafrost C cycle under climate warming. DOI: 10.1002/ange. Chang Lu, Xiangjiang Liu, Yunfeng Li 1, Fang Yu, Longhua Tang, Yanjie Hu 1, Yibin Ying Affiliation 1 §Key Laboratory for Ultrafine Materials of Ministry of Education, School of Materials Science and Engineering, East China University of Science and Technology, 130 Meilong Road, Shanghai 200237, China. The fertilization experiment further confirmed that P addition had stronger effects on plant growth than N addition in this permafrost ecosystem. Our results showed that changes in soil P availability rather than N availability played an important role in regulating the increases in gross primary productivity and the decreases in net ecosystem exchange along the thaw sequence. e., non-collapse and 5, 14, and 22 years since collapse) with an in-situ fertilization experiment (included N and P additions at the level of 10 g N m -2 yr -1 and 10 g P m -2 yr -1, respectively) in a Tibetan swamp meadow to evaluate ecosystem C-nutrient interactions upon permafrost thaw. Yunfeng Lu Gurong Shen, Jing Liu, Hao Bin Wu, Pengcheng Xu, Fang Liu. Here we combined two-year field observations along a permafrost thaw sequence (constituted by four thaw stages, i. However, compared with the widely accepted C-N interactions, little is known about the potential role of soil phosphorus (P) availability. ![]() Contributors : Yunfeng Yang Jizhong Zhou Xue Guo. It has been advocated that the potential nitrogen (N) release upon permafrost thaw could promote plant growth and thus offset soil C loss. Functional profiles of soil microbial communities in the alpine and temperate grasslands of China. The ecosystem carbon (C) dynamics after permafrost thaw depends on more than just climate change since soil nutrient status may also impact ecosystem C balance.
