Abstract:

80 hrs course introducing the principles of mathematical formulation and dynamic modeling of soil forming processes and their interactions, using transparant LOTUS/SYMPHONY spreadsheets and graphs of gradually increasing level of integration.


II. Technical Information

II.1 Executables:

Operating System(s): LOTUS-123 and LOTUS-SYMPHONY needed.

II.2 Source-code:

Programming Language(s): Fifteen spreadsheets available on Introduction, Climate,Soil water balance, Moisture characteristics, NumericalIntegration, Decalcification, Feldspar weathering, Organicdynamics, Polyacid model for deprotonation and Al complexation,culminating in podzolization.
