In between rains or irrigations, crops must fulfill their water needs using water reserves in the soil.
Under optimal conditions the soil, water, nutrients and plant roots are all in one location and in sufficient quantities. The umbrella-type potato cropping system currently used reduces the water volume retained in the soil and accessible to crops.
Modifying the cropping system design is an effective way to improve potato crop water-use efficiency and, thereby, lessen the risk of crops experiencing water stress. Furthermore, better water utilization means better nitrogen utilization!
From 2019 to 2022
Optimal water management
The knowledge developed at IRDA will enhance water-use efficiency by potato farmers.

The aim of this project was to set up a support service to equip producers and others in the industry to improve their irrigation management.

This three-year project looked at optimal ways to use a mix of flowering plants against caterpillar pests of crucifers.
This project aims to develop an accessible and user-friendly web application that let stakeholders search the IRDA potato soil database, one of the largest in Canada, to visualize the impact of growing practices and protocols on the biological, physicochemical, and agronomic characteristics of soils cultivated with different cropping systems.
