Flooded Soil Science

Repost from 2012:  Kate Scow – Professor of Soil Science and Microbial Ecology, UC Davis setup an excellent wiki entry about flooding on soils. Flooded soils occur with complete water saturation of soil pores, and generally result in anoxic conditions of the soil environment. Flooded soil environments may include such ecosystem as: rice paddies; wetlands (swamps,…

Thawing Permafrost Could Release Vast Carbon Deposits, Diseases

by Science World Report | January 8, 2014 | Release URL Dr Guido Grosse has been studying the Arctic for fourteen years to find out how the frozen ground, known as the permafrost, is reacting to an environment that is getting hotter all the time. The samples he has drilled out – in regions so…

New diseases threatening Britain’s livestock and crops because of global warming

The Independent – June 19, 2013: Bleak assessment of climate change means world was facing ‘a lot more unanticipated events’ Britain faces a wave of deadly new animal and plant diseases that threaten to wipe out crops and livestock as a direct result of global warming, the World Bank’s top agricultural expert has warned. The…

Soil carbon and climate change: from the Jenkinson effect to the compost-bomb instability

Study: Long-term warming equivalent to 10°C per century could be sufficient to trigger compost-bomb instability in drying organic soils Wiley: First generation climate–carbon cycle models suggest that climate change will suppress carbon accumulation in soils, and could even lead to a net loss of global soil carbon over the next century. These model results are qualitatively…
