Abstract
The response of native shortgrass prairie legumes to water and N additions was evaluated utilizing a replicated factorial design of 2 water and 2 N treatments. Responses measured were densities and aboveground biomass by species. Water treatment greatly increased both density and biomass of legumes, presumably because of more favorable conditions for N fixation and increased competitive advantage under N deficient conditions.
