Carbon Feedback Forest Soils Accelerate Global Warming 26-Year Study Projects
2017/10/25
After 26 years, the world’s longest-running experiment to discover how warming temperatures affect forest soils has revealed a surprising, cyclical response: Soil warming stimulates periods of abundan...
Study finds mercury levels in Arctic soils 5 times higher than temperate regions
mercury levels Arctic soils 5 times higher temperate regions
2017/7/24
Plants and soil in the Arctic tundra absorb and store mercury released into the atmosphere by industry and mining in the Earth's temperate regions, leading to soil mercury levels five times higher tha...
Neutralizing acidic forest soils boosts tree growth,causes spike in nitrogen export
Neutralizing acidic soils tree growth causes spike nitrogen export
2016/7/4
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
