    • 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. Analyses of soils data from eight Norwegian catchments 

      Reuss, J.O. (NIVA-rapport;2484, Research report, 1990)
      Assessment of critical loads for soil at the catchment scale requires estimates of soil properties characteristic of the catchment. Soil data collected in routine soil surveys must thus be aggregated both spatially and ...

    • 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 ...

    • Interpretation of SoilData from the Rain Project 

      Reuss, J.O. (NIVA-rapport;2294, Research report, 1989)
      Process-oriented models for prediction of soil and water acidification at the catchment scale require soil chemical and physical data as input parameters. Choice of soil properties characteristic for an entire catchment ...

    • Physiochemical properties of soils at Risdalsheia and Sogndal: RAIN project 

      Lotse, E.; Otabbong, E. (NIVA-rapport;1727, Research report, 1985)
      The RAIN project investigates the interactions between acid deposition, vegetation, soil and water. This report presents physical and chemical properties of soil samples collected in the fall of 1982. These are background ...

    • RAIN PROJECT. Report for the years 1988, 1989 and 1990 

      Wright, R. (NIVA-rapport;2557, Research report, 1991)
      The Rain Project encompasses 7 years of catchment-scale experiments with acid addition at Sogndal and acid exclution at Risdalsheia. At Sogndal runoff contains increasingly higher concentrations of SO4 and NO3 these are ...

    • Soil Chemistry 1983-86 at the Rain Project Catchments 

      Lotse, E.G.; Wright, R. (NIVA-rapport;2293, Research report, 1989)
      The aim of the rain project is to explain the effects of changed acid deposition on soils and waters. This report presents results from chemical and physical analyses of soil samples collected yearly 1984-1986 at the rain ...
