The bulletin reports on the first four years of the Maine Potato Ecosystem Project, a long-term, multidisciplinary study of alternative crop management strategies. The study site is a 15-acre tract on the northern boundary of the University of Maine's Aroostook Farm in Presque Isle, Maine, divided into 96 main plots that are grouped into four blocks. Each block is an area where soil survey data show similar soil characteristics. Thus, given the same production inputs, the crop output is expected to be the same on each plot within a block. Within each block there are 24 plots to which the different treatments have been randomly assigned. A treatment is a particular combination of the following factors: (1) pest management—conventiorial, reduced input, or biological; (2) potato variety—Atlantic or Superior; and (3) soil management—amended or unamended.
