Interactions between ecosystem nitrogen and bedrock control long-term calcium sources in Oregon Coast Range forests

Creator:

Hynicka, Justin D.

Abstract:

Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...
