Research Projects

Flexible management of nitrogen fertilization (fertilizer type and dose) as a function of temperature for better yields in organic cranberry production.

Assessment of the efficiency of biomethanation digestate as a fertilizer for field crops and as recycled bedding in dairy production.

This project addresses the risks posed by the spreading of manure and emissions released into the environment to the biosecurity of farms, as well as to the health of workers and nearby populations.

We will compare the ability of mixed protocols using blended green manure, with or without the addition of farm manure, to satisfy the nitrogen requirements of a silage corn rotation crop.

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.

This project will develop a versatile tool that will allow to simulate the impacts of agricultural practices on soil organic matter.

A labile carbon input would displace some phosphorus into the soil solution, thus making it available again for assimilation into growing plants.

This project will determine the optimal post-emergent nitrogen dose to apply.

Development of a growing out-of-soil organic raspberries in high tunnels protocol in a profitable and competitive manner with a view to selling products locally or to large retail chains.

This project will modify current protocols with the addition of labile carbon to preserve or rapidly restore the activity of beneficial microorganisms.

This research project, initiated by the CÉROM grain research centre, looks to assess the cost-effectiveness of nitrogen fertilizer applications improved by the addition of urea, for use with winter wheat crops grown in Québec.

The project measures the nitrogen contribution of sawdust mulch.

By enhancing our understanding: 1) of the nitrogen supply dynamics associated with the use of mixed green and farmyard manure applications, and 2) of the timeline of nitrogen uptake by garlic; we hope to fine-tune fertilization strategies so they meet the needs of garlic crops, while minimizing phosphorus accumulation and nitrogen leaching.

Based on previous work conducted at IRDA and our team’s expertise, this project looks to finalize the development of a robust and cost-effective swine slurry bioconversion system.
