Modelling water and nutrient dynamics in soil-crop systems : proceedings of the Workshop on "Modelling Water and Nutrient Dynamics in Soil-Crop Systems" held on 14-16 June 2004 in Müncheberg, Germany

Soil-crop-atmosphere interactions play a central role in the multiple functions of rural landscapes. Agro-ecosystem models are increasingly used to support decision making on different scales towards sustainable land use and management. This is accompanied by a demand of model users for model validation to get an idea about the reliability of models. This book contains articles from a workshop on "Modelling water and nutrient dynamics in crop-soil systems". Data sets from lysimeters and experimental fields of multiyear crop rotations were provided for modellers. A unique data set is provided of a 100 year long term field experiment regarding crop yield and organic carbon development under different management systems. The book includes a detailed description of data sets which can be used by modellers and the papers describe the applications of 18 different modelling approaches describing soil-crop-atmosphere interactions for water, nitrogen and carbon dynamics. A comparison of the models applied to the same data set is provided, which points out similarities and differences in the description of single processes between the model approaches.; This gives potential model users and decision makers the opportunity to compare the model outputs and get a closer insight about the applicability and required adaptations for the participating models.
