Ecosystems acquire nitrogen from the atmosphere, but this source can't account for the large nitrogen capital of some systems. The finding that bedrock can also act as a nitrogen source may help solve the riddle. See Letter p.78 Bioavailable nitrogen commonly limits plant growth in natural ecosystems. In the absence of humans, this essential nutrient is thought to come mainly from the atmosphere through bacterial metabolism. Morford et al. present measurements of the nitrogen concentration and… 
Direct quantification of long-term rock nitrogen inputs to temperate forest ecosystems.
Direct evidence for rock N weathering is provided in three temperate forest sites residing on a N-rich parent material in the Klamath Mountains (northern California and southern Oregon), USA, suggesting active biologically mediated weathering of growth-limiting nutrients compared to nonessential elements.
Mechanisms of Nanoparticle Formation and Reformation in the Atmosphere
Several relevant models of nanoparticle formation and reformation in the atmosphere are underlined: the mechanism of forming fine ash particles in coal-fired thermal power plants; carbon particulates


Increased forest ecosystem carbon and nitrogen storage from nitrogen rich bedrock
It is shown that bedrock comprises a hitherto overlooked source of ecologically available N to forests, and the possibility that bedrock N input may represent an important and overlooked component of ecosystem N and C cycling elsewhere is raised.
Nitrogen limitation on land and in the sea: How can it occur?
AbstractThe widespread occurrence of nitrogen limitation to net primary production in terrestrial and marine ecosystems is something of a puzzle; it would seem that nitrogen fixers should have a
Do Forests Receive Occult Inputs of Nitrogen?
The nitrogen (N) cycle of forest ecosystems is understood relatively well, and few scientists expect that major revisions will be necessary; most current work on N cycling focuses on improving the
Soil acidification and nitrogen saturation from weathering of ammonium-bearing rock
THE origin of small regions of extremely acidic (pH<4.5) soils in the Klamath mountains of northern California has long been a mystery. These acidic regions are devoid of coniferous vegetation,
Contribution of bedrock nitrogen to high nitrate concentrations in stream water
Concentrations of nitrate in stream water throughout the world are reported to be elevated relative to natural background levels. This enrichment is commonly attributed to anthropogenic activities
Proportions of Exposed Igneous, Metamorphic, and Sedimentary Rocks
Of the rocks exposed on the Earth9s surface, 66 percent (±3.5 percent) are sedimentary and 34 percent are crystalline, at the 95 percent confidence level. Extrusive igneous rocks average about
