Previous studies showed that measures were required to control populations of E. coli and zebra mussel larva in water from the St. Lawrence. A system using slow sand filtration and an aerated pond was therefore installed at a farm on Île d'Orléans. Although this system has been proven to be effective for resolving both these problems, the sand filter can become clogged due to increased turbidity levels in the river at certain times of year and algal blooms in the water column above the filter. To manage this clogging risk, the project automated pumping based on water turbidity and cover the filter to prevent light from entering the water and thus reduce algal bloom. These control measures will improve technology transfer to other farmers who want to draw water from the river.

The selection of a cultivar should be an essential element in any sound irrigation management strategy. This project aims to optimize water use in potato farming.

This project aims to explore and experiment new approaches and ways to preserve, develop, and enhance the MRC’s bio-food sector, and reduce or eliminate the water deficit on the island.
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
