The quantity of harvestable bioenergy depends on site conditions, cultivation intensity and cultivation aims. The estimation of biomass is realised by combining yield functions and crop rotation algorithms in a model.
Spatial data are visualised in Geographic Information Systems (GIS). The algorithms are programmed in the system ArcGIS 9.x © ESRI and the programming language Visual Basic for Application.
Model input data:
site specific:
· arable land · annual precipitation · soil fertility ·
regional specific:
· demand of food · statistics of live stock · bioenergy sites ·
Results of modelling are potential annual yield maps of dry matter with following attributes:
theoretical:
yield potential of crops and by-products (dry mass)
technical:
yield potential minus demand for food and fodder
bioenergy content of energy crops: biogas, bioethanol, biodiesel, synthetic biofuels
sustainable:
e.g. humus carbon balances, precipitation scenarios, energy crop rotations, yield increasing
