Cadmium sesquioxide metal binding capacity

The objective of the model is to assess the metal binding capacity of different soils for different metals and is based on the approach from Blume and Brümmer (1991). The methodology is based on a weighted parametric classification and consists of a series of lookup tables that allows the user to 'score' a number of soil attributes and to ultimately arrive at a total score. This total score is then translated into a textual description of relative binding class; six classes have been identified ranging from very strong to no binding capacity.
