Agri-environmental analyses laboratory

The Agri-Environmental Analysis Laboratory is active in a number of areas, including agronomy, fertility, soil science, hydro-agricultural management, water quality, and organic soil amendment management.


The laboratory, which is accredited by Ministère de l’Environnement et de la Lutte contre les changements climatiques (MELCC) and Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec (MAPAQ), provides analytical support for research in a number of areas of expertise, in accordance with the ISO/IEC 17025 international standard.

IRDA provides the following analytical services to universities and other research centres:

  • Basic agronomic analyses accredited by MELCC under the Agricultural Operations Regulation
  • Additional analyses not accredited by MELCC are available to researchers for
    • Soil profiles and physical analyses
    • Organic fertilizer analyses (manure, slurry and compost)
    • Plant analyses
    • Water analyses
  • Analyses for specific research needs and the development of analytical methods using a variety of analytical instruments, including:
    • ICP optical emission spectrometry
    • Manual and automatic colorimeters
    • GC-MS (liquid injection, headspace, and thermal desorption tube)
    • HPLC-UV-Visible and refractive index
    • GC-FID-ECD and GC-FPD for gas analysis

Examples of methods developed for internal and external research projects

  • Analysis of isothiocyanates (ITCs) in mustard for use in biofumigation
  • Analysis of ITCs found in mustard flowers and stems
  • Analysis of urea and uric acid in chicken manure to evaluate nitrous oxide (N2O) emissions following the spreading of manure
  • Analysis of inulin, glucose, and fructose in Jerusalem artichoke
  • Analysis of the biological stability index (BSI) and organic matter stability index (OMSI)
