Study on Engineering-Material Properties and Influences of Incubated Temperatures on Soil Carbon Decomposition

Abstract:

The mineralization of soil carbon materials potentially alters carbon release from soil and the atmospheric carbon concentration in engineering. Despite this central role in the decomposition of soil carbon materials, few studies have been conducted on how climate warming affects this carbon emissions and then response in return back. To study this, five soils were incubated in 5, 15, 25 °C for one month. Soil shifted to warming condition slowed down the increasing rate of decomposition causing by higher temperature. Furthermore, raising the soil environment temperature to 25 °C weakened the temperature sensitivity of the decomposition of these carbon materials, and the temperature sensitivity enhanced at lower temperature. This “thermal adaptation” of carbon material would potentially slow down carbon loss which accelerated by climate change technically.
