Canadian Grains Commission release revisions to grain grading guide

Aug 14, 2023

The Canadian Grain Commission has released revisions to the 2023 Official Grain Grading Guide. The Official Grain Grading Guide is a complete reference on grading grains, oilseeds and pulses.

It has been reviewed and adjusted for the 2023-24 crop year to incorporate changes to grade specifications and tolerance levels. Changes are recommended by the Western and Eastern grain standards committees based on findings of previous years. The guide is also reviewed/revised for definitions and grading procedures.

Updates to the Official Grain Grading Guide came into effect August 1st for the 2023-24 crop year.

Of note in this update, is the clarity provided in determining dockage for canola for export. For the full list of revision for 2023, visit the Canadian Grain Commission @grainsCanada.gc.ca.

Video: Dr. Emerson Nafziger: Nitrogen Fertilizer Rates for Corn

The Crop Science Podcast Show, Dr. Emerson Nafziger from the University of Illinois breaks down decades of nitrogen research. From the evolution of N rate guidelines to how soil health and hybrid genetics influence nitrogen use efficiency, this conversation unpacks the science behind smarter fertilization. Improving how we set nitrogen fertilizer rates for rainfed corn is a key focus. Discover why the MRTN model matters more than ever, and how shifting mindsets and better data can boost yields and environmental outcomes. Tune in now on all major platforms!

"The nitrogen that comes from soil mineralization is the first nitrogen the plant sees, and its role is underestimated."

Meet the guest:

Dr. Emerson Nafziger is Professor Emeritus of Crop Sciences at the University of Illinois at Urbana-Champaign, with degrees in agronomy from Ohio State, Purdue, and Illinois. His research has focused on nitrogen rate strategies and crop productivity. He co-developed the Maximum Return to Nitrogen (MRTN) model, which is widely used across the Midwest. His research spans N response trials, hybrid interactions, crop rotation effects, and yield stability.
