MatchClover is a web-based application to improve the selection of legume species for specific locations, intended uses, and management. It is based on research and extension information on forage and cover-crop legumes produced in Oregon and used throughout the US and the world. Consistently formatted information for each clover species has been developed with US and international experts and placed within a database allowing presentation in various complexity forms. Selection strategies are based on qualitative and quantitative tolerances to climatic and soil-based factors and species suitability for use as pasture, hay, silage, cover-crop, soil conservation and improvement, and beautification applications. Climatic and soil information is used to define conditions which are then compared with the legume species tolerances to determine how well-suited each species is for each specific location being considered. The intended use and management level information further refine the search for the most appropriate legume.
