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.

In a wheat/grain corn/soya rotation, green manure can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution.

IRDA was in charge of conducting the economic analysis for this project carried out by Club agroenvironnemental de l’Estrie (CAE Estrie).
The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop, or after it is harvested.
