Researchers at the National Key Laboratory of Humid Subtropical Mountain Ecology have set up soil warming tests at the Sanming Forest Ecosystem and Global Change Research Station in Fujian. The results show that the increase in temperature makes the variable carbon and inert nitrogen components increase by 28% and 20%; respectively; soil warming reduces soil microbial nitrogen use efficiency by 31%, but does not change microbial carbon use efficiency. Climate warming can alter microbial community structure and enzyme activity, and thus lead to severe imbalances in soil N and C decomposition in subtropical plantations.
The result is entitled Effects of artificial warming on different soil organic carbon and nitrogen pools in a subtropical plantation (doi.org/10.1016/j.soilbio.2018.06.007), published in the international journal Soil Biology and Biochemistry.The study was supported by the National 973 Program (No. 2014CB954003).
