Interpretation of SoilData from the Rain Project

Abstract

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 poses a major dilemma. This report deals with the interpretation of analyses from about 200 soils samples collected 1983-86 from the 7 catchments included in the RAIN project (Reversing Acidification In Norway). Various statistical techniques are used to derive characteristic values for key soil parameters such as cation exchange capacity, base saturation, bulk density, and anion absorption
