Agronomic, environmental, physical, chemical, and biological parameters are the main parameters used to determine soil health and agrosystem sustainability. However, the biological parameters that currently used are not accurate enough. Recent advances in biological and genomic analysis techniques have improved the affordability of detailed structural and functional characterizations of numerous biological communities that play essential roles in soil health and agroecosystem sustainability. The project was aimed at identifying and incorporating biological indicators into decision support tools used to assist producers and agroenvironmental regulatory bodies seeking to preserve soil productivity and use sustainable production systems. The project was a major innovation that enhanced our knowledge of factors that disrupt cropping programs and farming practices in Québec grain crops.
From 2016 to 2018
DNA sequencing can be used to inventory all the organisms living in a soil sample.

The project compared the nitrogen uptake effects of green manure crops grown for a full season, in association with a main crop, or after it is harvested.
This project relies on the continuous measurement of field water table heights; water exports; as well as sediment, nitrogen, and phosphorus runoff into drains at four field-crop production sites.
