Gis-based forage species adaptation mapping

Selecting forage crops adapted to the climatic and edaphic conditions of specific locations is essential for economic sustainability and environmental protection. Yet, currently, proper selection is difficult due to the absence of advanced selection tools. Significant improvements are being made in the process through Geographic Information System (GIS)-based mapping. Climate and soil GIS layers are being matched with forage characteristics through rules describing species tolerances. Better matching will reduce economic risks and environmental hazards associated with sub-optimal crop selection and subsequent performance. Once developed, these forage crop selection strategies and tools can be adapted for use with other crops. A matrix of species characteristics is being assembled for 6 major forage crops. GIS-based climate and soils maps are being developed and reviewed. Base layer climate and soils maps and the species adaptation maps will be placed on a CD-ROM to help educators, consultants, farmers, and ranchers match their conditions to suitable forage crop species. A WWW segment is being developed to provide a source of current information and links to original data and supplementary materials.
