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.

To provide information on the fertilizing value and environmental impact of spreading pig manure at different times, the project compared the effect of mineral fertilizer in early fall, late fall, and in the spring.
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.

The aim of the project is to assess the impact of applying various rates of glyphosate in field crop systems on the soil and crop rhizosphere microbiome.
