Temperature and moisture effects on the production of dissolved organic carbon in a Spodosol
- M. J. Christ, M. David
- Chemistry
- 1 September 1996
Leaching of dissolved organic carbon (DOC) from the forest floor is an important C flux and influences other biogeochemical fluxes in forests. To determine what controls the quantity and quality of… Expand
Carbon mobilization from the forest floor under red spruce in the northeastern U.S.A.
- M. Gödde, M. David, M. J. Christ, M. Kaupenjohann, G. Vance
- Environmental Science
- 1 September 1996
Global climate change may alter soil temperature and moisture conditions, increasing the need to understand how these basic factors affect C dynamics. This is particularly important in boreal… Expand
Patterns of nitrogen availability within a forested watershed exhibiting symptoms of nitrogen saturation
- William T. Peterjohn, C. J. Foster, M. J. Christ, M. Adams
- Environmental Science
- 28 June 1999
Watershed 4 (WS 4) at the Fernow experimental forest in West Virginia shows several symptoms of N saturation. Surprisingly, however, past measurements of N2O production suggest that a portion of WS 4… Expand
Nitrification potentials and landscape, soil and vegetation characteristics in two Central Appalachian watersheds differing in NO3− export
- M. J. Christ, William T. Peterjohn, J. Cumming, M. Adams
- Environmental Science
- 15 April 2002
Two watersheds within 1 km of each other in the Central Appalachian mountains of West Virginia have similar management histories and receive 13 kg of N in atmospheric deposition, but NO3 � export… Expand
Dynamics of extractable organic carbon in Spodosol forest floors
- M. J. Christ, M. David
- Chemistry
- 1 September 1996
Abstract Transport of dissolved organic carbon (DOC) from the forest floor to the mineral soil in Spodosols affects many biogeochemical processes. The nature of the C reservoir in organic soil… Expand
Nitrogen Retention Capacity of a Northern Hardwood Forest Soil Under Ammonium Sulfate Additions
- M. J. Christ, Y. Zhang, G. E. Likens, C. Driscoll
- 1 August 1995
To determine the N-retaining capacity of a beech-dominated stand in the Hubbard Brook Experimental Forest, we added (NH{sub 4}){sub 2}SO{sub 4} at three levels (40, 160 and 520 kg N{center_dot}ha{sup… Expand
Nitrous oxide production in two forested watersheds exhibiting symptoms of nitrogen saturation
- William T. Peterjohn, Richard J. McGervey, A. Sexstone, M. J. Christ, C. J. Foster, M. Adams
- Biology
- 1 November 1998
A major concern about N saturation is that it may increase the production of a strong greenhouse gas, nitrous oxide (N2O). We measured N2O production in two forested watersheds, a young, fertilized… Expand
Stable sulfur isotopic biogeochemistry of the Hubbard Brook Experimental Forest, New Hampshire
- Y. Zhang, M. Mitchell, M. J. Christ, G. Likens, H. R. Krouse
- Environmental Science
- 1 June 1998
In natural ecosystems, differences often exist in the relative abundanceof stable S isotopes (°34S) that can provide clues as tothe source, nature, and cycling of S. Values of °34S inprecipitation,… Expand
Microclimatic control of microbial C, N, and P pools in Spodosol Oa horizons
- M. J. Christ, M. David, P. McHale, M. Mitchell, L. Rustad, I. Fernandez
- Chemistry
- 1997
Nous avons examine les effets de l'humidite et de la temperature du sol sur C, N et P labiles (methode de fumigation et d'extraction au CHCl 3 ) dans les horizons Oa de deux Spodosols. La… Expand
Fractionation of dissolved organic carbon in soil water: Effects of extraction and storage methods
- M. J. Christ, M. David
- Chemistry
- 1 December 1994
Abstract We measured the concentration and composition (sensu Leenheer, 1981) of dissolved organic carbon (DOC) in lysimeter solutions from the forest floor of a spruce stand in Maine and in… Expand
