Elevated atmospheric carbon dioxide increases soil carbon
Global Change Biology, 2005AbstractThe general lack of significant changes in mineral soil C stocks during CO2‐enrichment experiments has cast doubt on predictions that increased soil C can partially offset rising atmospheric CO2 concentrations. Here, we show, through meta‐analysis techniques, that these experiments collectively exhibited a 5.6% increase in soil C over 2–9 years,

The Yasso07 soil carbon model – Testing against repeated soil carbon inventory
Forest Ecology and Management, 2012Abstract Forest soils store large amounts of carbon (C), and releases of C from this pool may significantly increase the CO2 concentration in the atmosphere. Organic matter decomposition in soils has been shown to strongly depend on temperature and soil moisture and is, therefore, susceptible to the climate change.

Highlights the significant economic, environmental, and societal benefits that result from land management practices that maintain or increase soil carbon (C). This book explores the potential for agricultural soils to generate soil C credits that could be traded in the broader greenhouse gas credit market and the benefits of farm programs ; https ...

Current farming practices deplete soil carbon, which degrades soil quality, reduces productivity, and results in the need for more fertilization, irrigation, and pesticides. No-till farming with residue mulching would reverse these effects by slowing soil erosion and pollution runoff, benefiting aquatic ecosystems, improving agronomic productivity, and

The gaseous composition of our earth's atmosphere has changed drastically in recent years. This has resulted in unprecedented global warming, hydrological variation, and various climate change impacts in different places of the world. Mitigation and adaptive strategies of climate change through soil carbon sequestration technique is emerged as an ...

The net carbon balance of forests is the small difference between very large fluxes of carbon uptake (via photosynthesis) and carbon loss (via respiration). If carbon uptake by forest vegetation exceeds C loss by vegetation and soils, the forest is a net sink of atmospheric carbon.

The quality of soil property maps may be improved and spatial sampling intensities reduced by incorporating secondary data to enhance spatial estimates. The purpose of this study was to evaluate how scale of sampling and secondary spatial information (terrain attributes) affected the quality of spatial estimates of soil C.

Total soil carbon (C) stock comprises of the soil organic C (SOC) and the soil inorganic C (SIC) components. The global SOC stock of ice-free land contains about 1,325–1,500 Pg (1 Pg = 1015 g) C in the top 1 m, 2,300 Pg C in the top 3 m, and 3,000 Pg C in the soil profiles.

Restoring soil carbon is essential to enhancing soil quality, sustaining and improving food production, maintaining clean water,and reducing increases in atmospheric CO2. Short-sighted farming practices have resulted in loss of an estimated 4 + 1 gigatons (Gt) of carbon from soils of the United States, and 78 + 12 Gt from the world's soils, a large ...
