Nitrogen solutes in an Adirondack forested watershed: Importance of dissolved organic nitrogen
Nitrogen (N) dynamics were evaluated from 1 June 1995 through 31 May 1996 within the Arbutus Lake watershed in the Adirondack Mountains of New York State, U.S.A. At the Arbutus Lake outlet dissolved organic nitrogen (DON), NO3 and NH + 4 contributed 61%, 33%, and 6% respectively, to the total dissolved nitrogen (TDN) flux (259 mol ha−1 yr−1). At the lake inlet DON, NO3 , and NH + 4 constituted ...
متن کاملDissolved organic nitrogen uptake by seagrasses
We examined the ability of seagrasses to take up dissolved organic nitrogen (DON) with leaves (in situ) and roots (laboratory) in an oligotrophic tropical offshore meadow in Indonesia using 15N-labeled nitrogen (N) substrates. We compared the uptake of urea and amino acids with that of ammonium (NH z4 ) and nitrate (NO { 3 ) and determined uptake kinetics of amino acids for the seagrasses Thala...
متن کاملDissolved organic nitrogen: an overlooked pathway of nitrogen loss from agricultural systems?
Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO(3)(-). Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to eutrophication and acidification, and can po...

متن کاملNitrate is an important nitrogen source for Arctic tundra plants
Plant nitrogen (N) use is a key component of the N cycle in terrestrial ecosystems. The supply of N to plants affects community species composition and ecosystem processes such as photosynthesis and carbon (C) accumulation. However, the availabilities and relative importance of different N forms to plants are not well understood. While nitrate (NO3-) is a major N form used by plants worldwide, ...
