This program is publicly distributed. "SPUR2
is a general grassland ecosystem simulation model designed to determine beef
cattle performance and production by simultaneously simulating production of
up to 15 plant species on 36 heterogeneous grassland sites. SPUR2 simulates
grassland hydrology, nitrogen cycling, and soil organic matter on grazed
ecosystems as well as rangeland production under different climatic regimes,
environmental conditions, and management alternatives. " SPUR
is the culmination of research by Dr. Jon Hanson, et. al.
WinSpur builds on the original DOS program that was created in the 1980's
and early 90's. The FORTRAN simulation core was recompiled for 32-bit
windows, and the DOS-menu interface was replaced by a windows interface.
The user interface allows the user to manage projects and edit the
configurable parameters in the projects. The program is designed for
version 2.4 projects, but users can import the older 2.2 projects, although
they may need to specify additional parameters after importing.
