Description

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.

Objective(s)

  • Intervene to increase the weight of tubers produced per unit of nitrogen supplied, and
  • Intervene to increase the quantity of tubers produced per unit of irrigation water supplied.
  • Compare the cropping systems, in terms of profit potential, with regards to their adoption and utilization.

Impact of manure management and tillage practices on water quality and safety in canola and wheat

Canola and wheat (wheat-corn-canola rotation) were planted in 2016 and 2017, respectively, on 12 experimental plots with tillage practices on the main plots (minimum tillage and chisel plow) and fertilization methods (mineral fertilizers, 25 m3/ha of pig manure and 50 m3/ha of pig manure) in the subplots.

Cost-benefit analysis of proposed actions to reduce the phosphorus load entering Missisquoi Bay from the Rivière de la Roche watershed

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.
