The purpose of this experiment is to measure the effect of NH4NO3 addition on vegetation under herbivore pressure. This experiment is located in fields A, B, and C. There are 3 treatments, 2 nitrogen levels and a control. The treatments are E, G, and I as defined in fertilization details under the "microplot" category. There are 16 reps of the 3 treatments for a total of 48 plots in each field. Treatments are randomly assigned to the plots. The plots are 4 by 4 meters and are laid out in a 6 by 8 grid with 1 meter aisles. For a list of treatments, see the treatment layouts in files trmte11. In 1987, experiment E053 was established on top of E011 in field C. For a list of treatments, see E053. Also is 1992, experiment (Walt Carson's) was established on top of E011 in field C. <!For a list of treatments, see E1??.> In the spring of 1992, experiment E100 was established on top of E011, in fields A, and B. For a list of treatments, see the treatment layouts in file trmte100 .
