Martin is professor of Cropping Systems and Natural Systems Agriculture at the University of Manitoba. In 1992, Martin founded the Glenlea long-term organic rotation study, Canada's oldest organic vs conventional comparison study. In the 1990's, Martin also conducted research on integrated systems such as no-till and crop-livestock integration. However since 2002, Martin has dedicated all of his research to improving organic agricultural systems. This effort has yielded innovations in agronomic management and plant genetics. For example, together with his staff and graduate students, Martin has developed a mulch-based system that allows no-till to be practiced in organic farming in certain years. Another example regards breeding crops specifically for organic production, a program that involves plant breeding colleagues at Agriculture and Agri-Food Canada and USC Canada. Since 2008, Martin and his students have conducted some of their work in southern and eastern Africa and in Asia. The focus of this work involves integration of legume plants into conservation agriculture systems.
