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 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.

This project’s main goal is to demonstrate how to satisfy most of the requirements of a strongly N-dependent crop by improving N-supply synchronization, while protecting the farmers’ prior year revenue-generating window.
