Soil samples: Soil samples collected for general use. To be left unground. Samples were collected pre-treatment. 4 samples per plot, and depth were homogenized. Two vials will be kept. COLLECTED: 8/2/1997

Experiment 146

Aboveground Biomass from Seed Addition Clip Strips: Aboveground biomass was obtained by clipping a 0.10m X 1m strip of vegetation in the center of the seed addition subplot. The clipped vegetation was sorted to species, dried and weighed. Subplots were harvested between 15August2000 and 21August2000. Bioma COLLECTED: 2000

Aboveground Biomass from Seed Addition Whole Subplot Harvest: Seed addition species were removed from the whole subplot before formation of viable seed in order to prevent dispersal of seed. The species removed were Lolium multiflorum, Setaria viridis, Melilotus alba, Chenopodium album, and Medicago lupulina. Aboveg COLLECTED: 2000

Aboveground Biomass from Transplants: Aboveground biomass of transplants was obtained by removing the plants from the plot and clipping off the roots. Plants were harvested between 31July2000 and 4August2000. The biomass was dried and weighed. Biomass from plots which were bareground plots in COLLECTED: 2000

Experiment 233

Soil Samples: The samples were collected for the prairie biofuels experiment using forty abandoned 32-species plots from E120. Plots were treated with one of three concentrations of nitrogen fertilizer or left as controls. Soil samples were taken at the following depth COLLECTED: October 2006

Experiment 235

Soil Samples: Soild Samples were collected for Carbon and Nitrogen Analysis COLLECTED: October 2007

Soil samples: The purpose of this experiment was to compare above ground biomass production on restored prairies to that of low diversity grasslands on a range of soil types and fertility levels. Visited 54 sites across the Upper Midwest (Minnesota, Wisconsin, Iowa and COLLECTED: Sept-Oct 2006
