A healthy humic balance is essential to ensuring soil health, conservation, and fertility. This project will develop a versatile tool that will allow farmers and their consultants to simulate the impacts of agricultural practices on soil organic matter. It will help users develop a long-term perspective on soil organic matter conservation, while managing crops on a day-to-day basis. The tool will support field diagnostic efforts by projecting how alternative management practices—crop choice, green manures, removal of crop residues (straw, stems, etc.), and organic soil amendments of various kinds—can impact the humic balance over time.
From 2019 to 2021
Field crops, Market gardening
Soil health, Fertilizer management
This tool will be used to predict soil changes stemming from the adoption of new agricultural practices.

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.

Ten test sites will operate over a two-year period on farms spread over ten Québec regions to compare the performance of winter and spring cereals.
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.
