This project proposes an intervention in a typical potato cropping system to enhance the crop uptake of water and nitrogen. We propose interventions that will increase the water-retention capacity (rainfall or irrigation) of the cropping system and increase the volume of soil colonized by the roots, where the nitrogen supplied has the potential to be taken up by the crop. With these interventions it should be possible to reduce the amount of nitrogen introduced in the form of fertilizer and, thus, reduce the risk of groundwater contamination.
From 2018 to 2019
Optimal water management, Fertilizer management
Optimal water management enhances crop performances and reduces the use of organic and mineral fertilizers.

Terranimo® tool adaptation at the terms and conditions of Québec.
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.
IRDA—in its capacity as the authorized representative tasked with revising the MAPAQ fertilization reference charts—will plan, coordinate, and monitor all activities involved in updating these charts.
