The first phase of the project involved 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 ultimate objective is to develop cropping scenarios or agricultural practices to be tested under experimental conditions and on farms and to a funding request to ensure the continuation of the project.
From 2015 to 2016
This work led to the development of cropping scenarios and agricultural practices to help boost the yields of grain producers.

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.
The aim of this project was to consolidate current scientific knowledge with a view to developing a spatially referenced tool to predict diffuse sediment, nitrogen, and phosphorus exports at the farm and watershed scale.
