David Rourke


David, along with his wife Diane, son Don, daughter Dorian and son-in-law John, runs one of Manitoba’s largest organic farms, Rourke Farms Organics, near Minto, MB. The Rourke’s transitioned to organic from conventional no-till in 2016. David has identified a lofty set of objectives for the farm including doubling the speed at which the farm creates soil organic matter, quadrupling profit, increasing farm diversity, eliminating the use of fossil fuels and increasing the nutrient density of food produced on the farm. Prior to the transition, David farmed conventionally while acting as President and CEO of AgQuest. AgQuest, founded in 1983, is the largest independent agricultural research provider in the Prairies. David has B.Sc. and master’s degrees (1981) in agriculture from the University of Manitoba


Alan McKenzie

 Alan farms a 4000 ac. cattle and grain farm near Nesbitt, MB on land purchased from his grandmother. The farm transitioned to organic starting in 2002 and all crops and livestock have been certified since 2011. Alan is experimenting with regenerative principles, incorporating a high degree of plant diversity and living roots. Weeds were not a big problem when much of the land base was in perennial pastures. As Alan moved away from a perennial system with livestock grazing on annual crops on land rotated through a series of cash crops such as hemp, mustard, wheat and multi-species cash crops, weeds became a bigger issue. Since then, Alan has relied on a mix of cultural and mechanical practices to manage weeds in this system.

Moderator: Will Baily-Elkin

He has worked on several mixed vegetable farms and is an IOIA-trained organic inspector. Currently, Will is a master’s student under the supervision of Dr. Martin Entz at the University of Manitoba. His research focuses on organic pea-intercropping.
