This project seeks to improve crop water supply and even limit topsoil nutrient runoff into waterways through the improved management of subsurface drainage systems. This will involve the installation of control units at the drain collector outlets. Our approach 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 in Montérégie. We will supplement our assessment of the controlled drainage trial results from these four sites with crop yield data. This will allow us to fine tune the system to yield optimal agronomic, economic, and environmental benefits.

This project aims to develop a digital decision support tool to improve the nutritional quality and yield of alfalfa from analyses of the nutritional quality of forages, based on its relationship with soil fertility and health, while including the other pedoclimatic parameters that define alfalfa production conditions.
