Rangeland: Plant responses to elevated CO{sub 2}
Nine circular plots were established on native tallgrass prairie near Kansas State University campus. Plots were separately exposed to ambient CO2, double ambient (enriched) CO2. Plots were moved annually in late February and have had various fertilization schemes applied. Grasses were examined for biomass production, water use efficiency, photosynthetic capacity, nutrient limitations, decomposition and nutrient cycling, and forage quality. It was found that C4, but not C3, grass species exhibited increased biomass production.
