Local agricultural stakeholders will collaborate with researchers and the regional and municipal governments to restore the rainbow smelt spawning grounds at the mouth of Rivière Boyer on the St. Lawrence River. The research team will provide the participants with a set of diagnostic spatial reference tools to assess diffuse emissions of sediment and phosphorus linked to runoff and erosion processes that affect croplands and waterways. This pilot project initiative includes an economic assessment component focused on helping farmers change their cropping systems and document the associated costs.
This project will spearhead three priority actions designed to
Ecosystem protection, Water protection
Up until the 1980's, Rivière Boyer had the largest rainbow smelt spawning grounds in the southern portion of the St. Lawrence estuary.

To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.
This project evaluated the impact of various corn, soya, and wheat fertilization methods on marketable yields, harvest quality, nitrate losses, and movement of microorganisms potentially pathogenic for humans.

This project relies on the continuous measurement of field water table heights; water exports; as well as sediment, nitrogen, and phosphorus runoff into drains at four field-crop production sites.
