The availability of arable land is limited in Québec and Ontario. With climate change and the intensification of farming, we will see a deterioration of soil health. The existing arable lands will experience increased production pressure as climate conditions shift to a new norm. Climate change will also spur the expansion of farming operations into regions where the climate is not currently conducive to cultivation. This will lead to the depletion of the soil’s organic matter content; the degradation of soil structure; an increase in erodibility; further runoff, erosion, and pollution of water bodies by sediments, nutrients, and pesticides; and an increase in CO2 atmospheric emissions. The intensification of farming activity will leave the soil even more vulnerable to degradation processes, which, in turn, will exacerbate the abovementioned effects. To mitigate the negative repercussions and ensure the future productivity of agricultural soils in Québec and Ontario, especially in areas where farming is currently limited, we must monitor the changes in soil health brought about by climate change and develop new soil conservation techniques accordingly.
From 2018 to 2021
This project could help to enable agriculture in areas where the climate is not currently conducive to cultivation.

A literature review, a survey of organic grain producers, and an analysis of historical yield and climate data in order to document the effects of climate extremes on yields and soil nutrient availability.

The goal of the project is to improve biological methods for controlling the cabbage seedpod weevil in canola crops. In this project, initiated by Agriculture and Agri-Food Canada and conducted in Québec by UQAM, IRDA is performing an economic analysis of the practices under study.

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.
