Abstract:
These data are measurements of plant species and nutrient composition for fertilized and unfertilized prairie ecosystems recorded at a long-term experiment (15-years) near Ames, Iowa, United States. We measured the plant species composition using a point-intercept method, recording species throughout the plot to determine overall species composition for each treatment. Additionally, we collected biomass samples and used an Organic Elementar Vario Micro Cube analyzer to determine the plant nutrient makeup of different grass species found in prairie ecosystems. These data provide insight into the make-up of prairie agro-ecosystems which can be used for further research and modeling efforts.
