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 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.

Increased forest ecosystem carbon and nitrogen storage from nitrogen rich bedrock
- Environmental ScienceNature

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.

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…
