Toward inventory‐based estimates of soil organic carbon in forests of the United States

Abstract: Soil organic carbon (SOC) is the largest terrestrial carbon (C) sink on Earth; this pool plays a critical role in ecosystem processes and climate change. Given the cost and time required to measure SOC, and particularly changes in SOC, many signatory nations to the United Nations Framework Convention on Climate Change report estimates of SOC stocks and stock changes using default values from the Intergovernmental Panel on Climate Change or country-specific models. In the United States, SOC in forests is monito… Show more

“…Our SOC estimates across forested areas are comparable to those reported on studies (Bolaños González et al, ; Domke et al, ). However, our results show high uncertainty across areas dominated with high SOC values (e.g., >1 g/cm 2 , some northern and tropical forests, peatlands, and other black soils dominated areas) and across higher latitudes (Figure ), as documented in previous studies (Tian et al, ).…”

“…The Forest Service is continually improving this process of obtaining carbon estimates from forest inventory (e.g., see Domke et al. , ). One result of these updates is that on average over 98% of ecosystem carbon on forest plots is estimated according to different conversion factors or models today (U.S. EPA ) relative to similar scope summaries from almost a decade ago (U.S. EPA , Heath et al.…”

“…While there are robust, broadly consistent methods for accounting for and predicting future C stocks in forest aboveground biomass, there is less consensus on methods for assessing belowground SOC. Long-term monitoring (Johnson & Todd, 1998;McLaughlin & Phillips, 2006), experimental manipulation (Edwards & Ross-Todd, 1983;Gundale et al, 2005), expert review (Jandl et al, 2007;Lal, 2005), quantitative synthesis ( These applications may be aided by promising advances in digital soil mapping (Mansuy et al, 2014;Mishra & Riley, 2015) and spatially explicit soil carbon assessments (Domke et al, 2017;Soil Survey Staff 2013).…”
