“…Similar concentrations and patterns in inorganic-N to the current study site (but mostly as NO 3 --N) were observed by Stevens et al (1995) in a freely draining ferric stagnopodzol, and were attributed to active nitrification in the freely draining soil. In contrast, Titus and Malcolm (1991) found that, due to a lack of nitrification following a rise in the WT after clearfelling, NH 4 + -N dominated the inorganic concentration in shallow groundwater.…”

“…Dissolved reactive phosphorus leaching from degrading brash material to the underlying soil has been measured in many studies (Stevens et al, 1995;Väänänen et al, 2007;Rodgers et al, 2010;Finnegan et al, 2012). On the same study site, Finnegan et al (2012) found that DRP concentrations 13 were significantly higher under 5 year-old brash mats in the RB than in the adjacent SF,…”

“…Stevens et al (1995) found that the brash material from their site in North Wales, which was planted with Sitka spruce, contained 32 kg ha -1 of P and 291 kg ha -1 of N. After clearfelling, up to 10 kg ha -1 of P (within one year after felling) and 14 kg ha -1 of inorganic N (within four years of clearfelling), with the majority of this being NH 4 + -N, and was found in the brash throughfall (Stevens et al, 1995). Large amounts of P can be easily released from brash material, but N varies from small releases (approximately 5%…”

“…In this study, SRP and TDP concentrations observed for upper soil horizons are one to two orders of magnitude higher than reported for other climatic and physiographic zones. P concentration in leaf litter leachate from spruce plantations on acidic Podzolic soils in Wales after harvest ranged from near 0 to 0.6 mg L -1 (Stevens et al 1995). Cortina et al (1995) observed SRP in pine plantation forest floor leachate in Spain to vary from 0.02 to 2.50 mg L -1 , with highest values in summer.…”

. 2005. Trends in dissolved phosphorus in Gray Luvisol soil profiles after forest harvest . Can. J. Soil Sci. 85: 89-101. Forest disturbances that increase P export from hillslopes will have negative consequences for site productivity and regional water quality. We studied P behavior in Gray Luvisols to understand the soil profile's influence on P export from typical hillslopes of the Boreal Plain ecozone. We hypothesized that (1) P concentration is highest in upper horizons, (2) solution P is primarily in the dissolved and organic form, and (3) forest harvest will increase solution P concentration. We analyzed the soil solution, with emphasis on P, and determined P sorption properties of key soil horizons. Mean soluble reactive phosphorus concentration decreased with depth, ranging from 64 mg L -1 in the forest floor to 0.01 mg L -1 in the groundwater zone; solution P was mostly orthophosphate. Water soluble phosphorus decreased from 74 ± 9 to 41 ± 9 mg L -1 and extractable phosphorus was reduced in the forest floor only on two of four sampling occasions after harvest. Dissolved organic carbon may indirectly promote orthophosphate dominance in solution by complexing metal cations that would otherwise precipitate metal-P from solution. Gray Luvisols probably export P to soils lower on the hillslope catena, such as those of the Gleysolic and Organic Orders, both commonly associated with wetlands.Key words: Forest soil, phosphorus, orthophosphate, Gray Luvisol, biogeochemistry, sorption Whitson, I.

Les aménagements forestiers qui accentuent l'exportation de phosphore (P) des pentes voisines auront des répercussions néfastes sur la productivité du site et sur la qualité des eaux locales. Les auteurs ont étudié le comportement du P dans les luvisols gris afin de mieux comprendre l'incidence du profil sur l'exportation de cet élément à partir des pentes typiques dans l'écozone des plaines boréales. Pour cela, ils ont formulé les hypothèses suivantes : (1) la concentration la plus élevée de P se retrouve dans les horizons supérieurs; (2) la solution phosphorée se compose surtout de P dissous et organique; (3) l'exploitation forestière concentre la solution P. Ils ont ensuite analysé la solution de sol en insistant sur le P et établi les propriétés de sorption du P pour les principaux horizons. La concentration moyenne de phosphore soluble réactif diminue avec la profondeur, pour passer de 64 mg par litre dans le sol forestier à 0,01 mg par litre dans la nappe phréatique. La solution P se compose principalement d'orthophosphates. La concentration de phosphore hydrosoluble baisse de 74 ± 9 à 41 ± 9 mg par litre, mais celle de phosphore extractible dans le sol forestier n'a diminué qu'à deux occasions sur quatre lors de l'échantillonnage après récolte du bois. Le carbone organique dissous pourrait entraîner indirectement la domin...
