Title: Networking our science to characterize the state, vulnerabilities, and management opportunities of soil organic matter

Abstract

Soil organic matter (SOM) supports the Earth's ability to sustain terrestrial ecosystems, provide food and fiber, and retains the largest pool of actively cycling carbon. Over 75% of the soil organic carbon (SOC) in the top meter of soil is directly affected by human land use. Large land areas have lost SOC as a result of land use practices, yet there are compensatory opportunities to enhance productivity and SOC storage in degraded lands through improved management practices. Large areas with and without intentional management are also being subjected to rapid changes in climate, making many SOC stocks vulnerable to losses by decomposition or disturbance. In order to quantify potential SOC losses or sequestration at field, regional, and global scales, measurements for detecting changes in SOC are needed. Such measurements and soil-management best practices should be based on well established and emerging scientific understanding of processes of C stabilization and destabilization over various timescales, soil types, and spatial scales. As newly engaged members of the International Soil Carbon Network, we have identified gaps in data, modeling, and communication that underscore the need for an open, shared network to frame and guide the study of SOM and SOC and their management formore » sustained production and climate regulation.« less

(a) Spatial variability of soil organic carbon (SOC) stocks in the upper meter of soil (where 1 kg C m-2 = 10 Mg C ha-1), based on the WISE 3.1. database (Batjes, 2016).(b) Fractional human use ofmore » the land surface through forestry, grazing and agricultural crops based on the data by Erb et al. (2007); grey areas represent unused land. (c) Global SOC stocks (0–1 m) distributed under different land-use categories. (d) Potential opportunities for gross annual SOC sequestration in presently managed forest, crop, and grazing lands (assuming average management C gains of 0.04 kg C m-2 year-1 with error bars showing the range of 0.01–0.07 kg C m-2 year-1; Minasny et al., 2017) could compensate for total emission projections from permafrost-C due to the climate feedback (Koven et al., 2015; mean and range of projection until 2100 under RCP8.5) and the projected impact of “human land use,” defined as land use change, agricultural representation, crop harvest, and management (Pugh et al., 2015; mean and ensemble range of projection until 2100 under RCP8.5). Note that harvest from forestry is not included in this last projection« less
