Identifying customers’ priority research needs is one of the most critical steps to guiding the development of technology with the highest relevance and adoption potential. The New England Plant, Soil and Water Laboratory (NEPSWL) held a Research Visioning Workshop for the Maine potato industry, where their number one research priority was finding and developing profitable crop rotations for potatoes. In response to this research direction, 14 different cropping systems were evaluated for their impacts on potato yield and quality, nutrient availability, plant diseases, soil microorganisms, potential profitability, economic risk, and other factors. This information was developed into the “Potato Systems Planner,” a decision support tool on compact disc that assists growers with selecting profitable, environmentally sound cropping systems and management practices. For example, the Planner shows that growing sweet corn in rotation with potatoes can increase profitability by $400/acre. It also shows that the probability of an economic loss for the sweet corn-potato system is only 3%, while that for the potato-potato system is 37%. Furthermore, growing canola before potatoes reduces soil-borne diseases by 20- 50%, which translates into higher potato yield and quality, along with substantial economic, environmental, and health/safety benefits associated with less pesticide needed to control these diseases. These and many other research findings are presented in the Potato Systems Planner so that growers can make the most informed cropping system selections and employ the most appropriate management practices that are economically and environmentally sustainable. Since its release in 2005, over 1100 copies of the Potato Systems Planner have been requested by growers, consultants, extension specialists, and scientists who are now using the Planner in 26 states, 8 Canadian provinces, and 28 countries. The Potato Systems Planner was selected as one of only 11 science-track presentations at the World Potato Congress in Idaho and an International Symposium on Farming Systems in Italy. The transfer of this technology to customers, stakeholders, and federal laboratory partners is continuing to this day.
