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.

The project evaluated and compared the effectiveness of two types of subsoil plows (mounted on a bulldozer or a tractor) operated parallel and perpendicular to the tile drains to improve soil drainage conditions and productivity compared to control plots.
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.
A better understanding of risk factors that favour the development of this disease will help Québec farmers adopt more environmentally friendly and cost-effective control strategies.
