P. Schall et al., MODELING ASPECTS OF FOREST DECLINE IN GERMANY - II - APPLICATION AND VALIDATION OF AN INTEGRATED SOIL-PLANT-MODEL, Chemosphere, 36(4-5), 1998, pp. 971-978
In 1993 the German Federal Environmental Agency initiated a project to
evaluate the forest decline research of the period 1982-1992 in Germa
ny. The soil-plant-model PLOT applied here was developed to integrate
the research results. It consists of a soil module, BODEN, and a plant
module, FICHTE, which both include several submodels. For validation
of submodels, modules, and the whole model, a stepwise procedure was c
hosen and parts will be presented here. Focussing on soil processes an
d nutritional aspects, the model performance as well as the applicabil
ity range and limits are shown. The underlying cause-effect-relationsh
ips and the theoretical aspects of the modelling exercise are presente
d in a second paper [1, this volume]. (C) 1998 Elsevier Science Ltd.
