Lori Robinson, a 6th generation farmer in PEI, is a data hound.  As a result of her 50+ years of her and her family taking detailed notes and 20 + years of doing a four-year crop rotation system she laid the groundwork for a user-friendly calculator for crop rotations that has both economic benefits for producers and environmental benefits. Developed at the Living Labs initiative in PEI in conjunction with the PEI Potato Board, the calculator helps producers maximize profits while reducing their use of pesticides and improving soil health. And the story of the calculator has some interesting twists.
