Systematic review reveals soil organic carbon benefits of alternative grazing depend on study quality
Abstract There is enormous interest in utilizing alternative grazing strategies to improve rangeland condition, increase profitability and decrease the carbon footprint of livestock production via soil organic carbon (SOC) sequestration. Here we present a systematic review and meta-analysis of the literature on alternative grazing strategies and their impact on soil organic carbon. Most studies (47 out of 70) did not satisfy multiple quality criteria.
Data from long-term experiments in temperate croplands to evaluate soil organic carbon models - Scientific Data
|
Abstract Soil organic carbon (SOC) models need independent evaluation against field measurements, but those latter are rarely publicly available and harmonized. In this study, we collected and shared data from 167 agronomic treatments in 34 agronomic long-term experiments (LTEs) located in temperate croplands, allowing the evaluation of several soil organic C models such as RothC, Century, AMG, MIMICS, ICBM, Millenial, and CTOOL.

Coupling Remote Sensing With a Process Model for the Simulation of Rangeland Carbon Dynamics
1 Introduction Rangelands, which include a wide range of semi-arid to arid landscapes primarily composed of grasses, forbs, and shrubs that are often grazed or browsed by domestic livestock and/or wildlife. Rangelands cover more than 30% of the land area (∼2.7 million km2) of the contiguous United States and 54% of all land globally (Chen et al., 2015; Olson et al., 2001; Reeves & Mitchell, 2011).

Global-change controls on soil-carbon accumulation and loss in coastal vegetated ecosystems
Abstract Coastal seagrass, mangrove and salt-marsh ecosystems—also termed blue-carbon ecosystems—play an important role in the global carbon cycle. Much of the organic carbon they store rests in soils that have accumulated over thousands of years. Rapidly changing climate and environmental conditions, including sea-level rise, warming, eutrophication and landscape development, will impact decomposition and thus the global reservoir of blue soil organic carbon.
Comment on “Climate legacies drive global soil carbon stocks in terrestrial ecosystems”
Delgado-Baquerizo et al. (Science Advances, 12 April 2017, e1602008) use statistical correlations to infer that paleoclimate (6000 to 22,000 years ago) is a more important driver of current soil organic carbon stocks than the current-day climate. On the other hand, a wealth of radiocarbon measurements indicates that the organic carbon in most topsoils is only a few decades to perhaps a few centuries old.
Soil carbon debt of 12,000 years of human land use
Land use and land cover change has resulted in substantial losses of carbon from soils globally, but credible estimates of how much soil carbon has been lost have been difficult to generate. Using a data-driven statistical model and the History Database of the Global Environment v3.2 historic land-use dataset, we estimated that agricultural land uses have resulted in the loss of 133 Pg C from the soil.
Pyrogenic carbon distribution in mineral topsoils of the northeastern United States
Due to its slow turnover rates in soil, pyrogenic carbon (PyC) is considered an important C pool and relevant to climate change processes. Therefore, the amounts of soil PyC were compared to environmental covariates over an area of 327,757 km2 in the northeastern United States in order to understand the controls on PyC distribution over large areas.
