Methods for Experiment 111 -

Experiment Design

In the summer of 1992, LTER experiment 111 was initiated on an abandoned agricultural field that had the top 60-80 cm of soil removed with a bulldozer. This monoculture garden was set up adjacent to the existing competition gardens (LTER experiments 26, 55, 69 and 70). The 160 total plots consist of two plot sizes, large (5 ft x 8ft) and small (5 ft x 4 ft) were built using sheet metal pounded into the ground. The entire garden is surrounded by a 6 foot tall fence above ground and a 4 foot tall fence below ground to exclude herbivores. Seeds were planted in the fall of 1992. Plots were weeded each year to maintain monoculture status. Appropriate treatments were administered to each experiment and sampling was done according to sampling schedules during the 1992 field season. Species plot table
