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.

This project will develop a versatile tool that will allow to simulate the impacts of agricultural practices on soil organic matter.
This project was aimed at identifying and incorporating biological indicators into decision support tools used to assist producers and agroenvironmental regulatory bodies seeking to preserve soil productivity and use sustainable production systems.

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.
