In a wheat/grain corn/soya rotation, green manure as the main source of nitrogen, complemented in the grain corn year by a quickly available manure-based nitrogen starter fertilizer, can be used to obtain profitable organic grain corn yields while limiting phosphorus pollution. The project was conducted at IRDA’s Organic Agriculture Innovation Platform.
From 2015 to 2018

The Rivière de la Roche sub-watershed has one of the highest phosphorus and sediment export rates of the entire Missisquoi Bay watershed—a particularly challenging situation for the local agricultural sector.
This project was carried out by Club agroenvironnemental de l’Estrie and IRDA was in charge of conducting the economic analysis.
