2018-2020 • Market gardening

Evaluating the effect of seeds coated with commercial, mycorrhizal fungi inoculum on the yields of nantes carrots grown in mineral soil early in the organic transition process

Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.

2018-2020 • Field crops

A study on synchronizing the supply of n from green manure in order to reduce or replace the use of swine slurry as a fertilizer for post-emergent corn, in the context of the transition to organic farming

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.

Validating tools used to reduce soil phosphorus saturation by monitoring soil tests and phosphorus loads in an intensive livestock region

The aim of this project is to show that efforts made to better distribute phosphorus on the land are effective and that the indicators used to determine phosphorus saturation thresholds are correlated with soil phosphorus balance and dynamics.

2016-2019 • Market gardening

Integrated approach to nitrogen fertilization for profitable organic potato production and a balanced phosphorus budget

There is a great need to test green manure as a main source of nitrogen for potatoes as they help to maintain soil quality and control weeds.

2017-2019 • Market gardening

Combining slow release and conventional nitrogen fertilizer to reduce leaching and stabilize annual potato yields

Meeting nitrogen requirements mainly through the use of a highly stable form of fertilizer can minimize nitrogen losses, provide nitrogen amounts closer to the plant’s actual needs.
