Experiment 008 - Effect of N Addition on Vegetation with Mammalian Herbivory

The purpose of this experiment is to look at the effect of NH4NO3 addition in an unfenced area. The experiment is located in field E. There are 4 different treatments C, F, H, and I as defined in fertilization details in the "microplot" strategy. The plots are 4 by 4 meters and are laid out in an 8 by 8 grid with 1 meter aisles. From 1989-1994 plots with fertilizer treatment 1 were treated as complete controls, receiving no nutrients at all.
