AbstractExamines the mechanism underlying the positive effect of plant species diversity on productivity. Echinacea purpurea seedlings were grown in soil from 10-year-old experimental plant communities that varied in species diversity. Soil collected from the most diverse communities resulted in greater biomass than soil collected from monocultures. The increase in biomass was attributed to greater Nitrogen availability likely through plant functional groups that both supplied and retained nutrients.
