    • Critical loads for soil in Norway, Nordmoen 

      Wright, R.; Stuanes, A.; Frogner, T. (NIVA-rapport;2605, Research report, 1991)
      We evaluate the critical load for soil and water at Nordmoen using the dynamic model Magic, the static PROFILE model, and the empirical method as suggested by the mapping handbook. Nordmoen is located about 60 km N of Oslo ...

    • Critical loads for soils in Norway. Preliminary assessment based on data from 9 calibrated catchments 

      Wright, R.; Stuanes, A.; Reuss, J.O.; Flaten, M.B. (NIVA-rapport;2483, Research report, 1990)
      Critical load for acid deposition with respect to soils are calculated for 9 calibrated catchments in southern Norway. Two methods recommended by the UN-ECE Handbook on Mapping Critical Loads were used: The stratic empirical ...

    • Gårdsjön Status Report for 1991-1992: The first Year of Treatment 

      Anderson, I.; Brandrud, T.E.; Dise, N.; Clemensson-Lindell, A.; Hultberg, H.; Huse, M.; Kjønnaas, J.; Moldan, F.; Nygaard, P.H.; Nystrøm, U.; Persson, H.; Rudi, G.; Stuanes, A. (NIVA-rapport;2915, Research report, 1993)
      Nitrogen addition weekly to catchment G2 at Gårdsjön began April 1991. During the first year of treatment a total of 230 meq/m²yr NH4No3 was added in 33 mm of water plus 90 meq/m²/yr deposited in 631 mm throughfall. Runoff ...

    • Nitrex project - Gårdsjöen, Status report for 1990-91 

      Dise, N.; Wright, R.; Andersson, I.; Brandrud, T.E.; Carlsson, U.; Clemensson-Lindell, A.; Hauhs, M.; Hultberg, H.; Huse, M.; Kjønnaas, J.; Klemedtsson, L.; Kroglund, F.; Müller, D.; Nygaard, P.H.; Nyström, U.; Stuanes, A.; Wohlfeil, I. (NIVA-rapport;2694, Research report, 1992)
      At the NITREX site at Gårdsjön, Sweden, ambient nitrogen deposition of 90 meg m² yr 1 will be experimentally increased by 286 meg m² yr 1 to an entire forested catchment G2 to study the potential for nitrogen saturation. ...

    • NITREX project - Gårdsjøn. Status report for 1988-1990 

      Wright, R.; Brandrud, T.E.; Kroglund, F.; Wohlfeil, I.; Andersson, I.; Carlsson, U.; Clemensson-Lindell, A.; Hultberg, H.; Kjønaas, J.; Müller, D.; Nystrøm, U.; Persson, H.; Stuanes, A. (NIVA-rapport;2545, Research report, 1991)
      At the NITREX site at Gårdsjøn, Sweden, nitrogen deposition will be experimentally increased to an entire forested catchment to study the potential for nitrogen saturation. Investigations include regular sampling of ...

    • Nitrogen fra fjell til fjord. Årsrapport 1995. (Nitrogen from mountains to fjords - yearly report 1995) 

      Kaste, Ø.; Berge, D.; Fjeld, E.; Høyås, T.; Mulder, J.; Stuanes, A.; Tørseth, K. (NIVA-rapport;3504, Research report, 1996)
      Programmet "Nitrogen fra fjell til fjord" har som hovedmål å øke kunnskapen om opptak, omsetning, retesjon og avrenning av nitrogen, og å gi bedre prognoser for framtidige effekter av endringer i nitrogenkretsløpet på jord, ...
