AMMONIUM TRANSFORMATION IN A NITROGEN-RICH TIDAL FRESHWATER MARSH

Gribsholt B.; Struyf E.; Tramper A.; Andersson M.G.I.; Brion N.; De brabandere L.; Van damme S.; Meire P.; Middelburg Ja.J.; Dehairs F.; Boschker H.T.S. (2006)

The fate and transport of watershed-derived ammonium in a tidal freshwater marsh fringing the nutrient rich Scheldt River, Belgium, was quantified in a whole ecosystem 15N labeling experiment. In late summer (September) ...
FINE ROOTS VS. NEEDLES: A COMPARISON OF 13C AND 15N DYNAMICS IN A PONDEROSA PINE FOREST SOIL

Bird J.A.; Torn M.S. (2006)

Plant allocation patterns may affect soil C and N storage due to differences in litter quality and the depth of plant C and N inputs into the soil. We studied the dynamics of dual-labeled (13C/15N) Pinus ponderosa needles ...
LAND-USE CHANGE EFFECTS ON SOIL C AND N TRANSFORMATIONS IN SOILS OF HIGH N STATUS: COMPARISONS UNDER INDIGENOUS FOREST, PASTURE AND PINE PLANTATION

Parfitt R.L.; Scott N.A.; Ross D.J.; Salt G.J.; Tate K.R. (2003)

Globally, land-use change is occurring rapidly, and impacts on biogeochemical cycling may be influenced by previous land uses. We examined differences in soil C and N cycling during long-term laboratory incubations for the ...
REGIONAL ASSESSMENT OF N SATURATION USING FOLIAR AND ROOT δ15N

Pardo L.H.; Templer P.H.; Goodale C.L.; Duke S.; Groffman P.M.; Adams M.B.; Boeckx P.; Boggs J.; Campbell J.; Colman B.; Compton J.; Emmett B.; Gundersen P.; Kjønaas J.; Lovett G.; Mack M.; Magill A.; Mbila M.; Mitchell M.J.; Mcgee G.et al. (2006)

N saturation induced by atmospheric N deposition can have serious consequences for forest health in many regions. In order to evaluate whether foliar $\delta^{15}\hbox{N}$ may be a robust, regional-scale measure of the ...
SOIL N CHEMISTRY IN OAK FORESTS ALONG A NITROGEN DEPOSITION GRADIENT

Nilsson L.O.; Wallander H.; Bååth E.; Falkengren-grerup U. (2006)

Anthropogenic N deposition may change soil conditions in forest ecosystems as demonstrated in many studies of coniferous forests, whereas results from deciduous forests are relatively scarce. Therefore the influence of N ...
