6 FAQs about [Soil energy storage pool]
How do we calculate carbon storage in vegetation and soil pools?
We used the carbon transfer rate (or turnover time) method to calculate carbon storage in vegetation and soil pools. These results will aid in assessing carbon budgets and in predicting ecosystem carbon responses to climate change.
Do vegetation and soil carbon pools have stable carbon storage?
Both vegetation and soil carbon pools have relatively stable carbon storage (Yang et al. 2010, Fang 2011), even though carbon is continuously moving between among vegetation, soil, and the atmosphere (Dixon et al. 1994, Wang et al. 2001).
Do soil carbon pools control the global distribution of Pops?
The background levels of POPs were estimated in conjunction with the global soil database. It led to the proposition that the stable soil carbon pools are key controlling factors affecting the ultimate global distribution of POPs, so that the dynamic cycling of soil carbon acts to counteract the cold-trapping effects.
How much SOC and sic is stored under the topsoil layer?
This study discovered that the SOC and SIC storage of the whole soil profile (0–20 m) was 9 and 24 times that of the topsoil layer (0–1 m), respectively. The results indicated that the study area stores large amounts of SOC and SIC below the topsoil profile.
What affects labile soil carbon pools in subtropical forest and agricultural ecosystems?
Labile soil carbon pools in subtropical forest and agricultural ecosystems as influenced by management practices and vegetation types. Agric. Ecosyst. Environ.65: 69–78 [Google Scholar] HuangW, SpohnM. 2015. Effects of long-term litter manipulation on soil carbon, nitrogen, and phosphorus in a temperate deciduous forest.
Is soil carbon storage underestimated?
Furthermore, since SIC storage is a substantial component, 9–10 times SOC storage in the 0–20 m soil profiles for different land uses (Fig. 4 a,b). Therefore, soil carbon storage might have been greatly underestimated in this area and other similar regions 9, 44, 45.
