Several soil cores were collected in each plot to sample root biomass. Soil coring allows observation of belowground growth without ripping up plants.

Researchers collect aboveground biomass and record data in Nutrient Network plots.

Nutrient Network Plots at the Cedar Creek LTER site. Square plots have had different combinations of nutrients added. Differences in aboveground growth as a result of nutrient addition are visible across plots.
