Submitting Grain Samples for Grading

It is important to know the grade and dockage of your grain prior to marketing to ensure that you receive a fair price for your grain. The Canadian Grain Commission (CGC) provides the following grain grading services:

The Canadian Grain Commission’s Harvest Sample Program
The Harvest Sample Program provides unofficial grade and quality results at no charge for most grain, oilseed, and pulse crops.  Samples are submitted at harvest time and results are emailed to the producer.  Producers who have previously signed up for the Harvest Sample Program will receive a Harvest Sample kit annually.  For more information on the Harvest Sample Program or to sign up visit the CGC website.

Producer Request for Inspection Services
Producers that did not participate in the Harvest Sample Program but would still like to receive a grade for their grain can submit a sample to the CGC for a fee.  It is important to submit a representative grain sample as the grade received should accurately represent grain stored in a bin.  Instructions on representative grain sampling can be found on the CGC website.  Once you have a representative sample, complete the request for inspection services form I-106 and send the sample by mail or courier to the CGC Weyburn office for inspection.  Instructions and additional tests available are found on the form.

What steps can be taken when you disagree with an elevator’s assessment of your grain’s grade and dockage?
As legislated under the Canadian Grains Act producers can dispute a licensed primary elevator’s assessment of their grain. If you do not agree with the assessment of your grain at the time of delivery, you can ask that a representative sample of your grain be sent to the CGC for inspection. Payment for your grain will be subject to the inspectors grade and dockage. For more information, visit the dispute your grain grade section of the CGC website.

Tips to Marketing Downgraded Crops

Over the past few weeks, we’ve heard about the impact of the poor weather conditions over the harvest period on the quality of harvested grain.  With the crop off the field and into the bin, marketing now becomes the focus of many producers.

In the attached article (updated from 2014) by Gary Smart, Farm Management Specialist with Manitoba Agriculture, he provides excellent information to cope with downgraded crops.  Some highlights include:

  • When marketing poor quality grain, be prepared and don’t panic, especially right at harvest time.
  • Know the quality and find a buyer who will offer the best value.
  • Take good samples. Without thorough samples, it is tough to know what is actually in the bin.
  • Communicate with the buyer if already some of this year’s crop is already contracted.
  • Unless cash flow is an issue on the farm, being patient could be the best action to take as new markets may arise for poor quality grain.

What Moisture/Temperature is Recommended Grain Storage?

Submitted by Anastasia Kubinec, MAFRD Oilseed Crop Specialist

Within the first 6 weeks of harvesting grain, bins should be checked regularly for change in temperature, moisture and watching out for spoilage.  After the 6 week mark, sampling and monitoring should still be occurring to ensure grain is at the appropriate temperature/moisture to store long-term over the winter. 

The Canadian Grain Commission has charts available on their website that indicated the proper temperature and moisture of each type of grain.

Continue to monitor your grain over the winter months, until it is shipped to the buyer, to ensure that the quality put into the bin is the quality coming out of the bin!

Preliminary protein data by crop region available for Canada Western Red Spring wheat

WINNIPEG, Oct. 7, 2014 /CNW/ – Preliminary protein content data for the 2014 Canada Western Red Spring wheat harvest are now available by crop region.

Data on protein will be updated every Tuesday while samples are received for the Canadian Grain Commission’s 2014 Harvest Sample Program. Grain producers can register for the Harvest Sample Program until October 31, 2014. The Canadian Grain Commission will accept samples until November 30, 2014.

Quick facts

  • The Canada Western Red Spring wheat quality data will be released in 3 phases:
    • Protein content only by crop region and grade, based on individual samples received. Data will be updated weekly.
    • Key quality parameters by crop region and grade, based on regional composites, when sufficient representative samples from each crop region have been received and composites have been made for analysis.
    • Comprehensive quality analysis by grade with protein segregation, where applicable, based on final composites. A comparison to 2013 data will be available.
  • Grain producers participate voluntarily in the Harvest Sample Program. They submit representative samples. We combine samples by crop, class and grade and analyse quality parameters that reflect end-use quality and performance. The data are used by marketers, millers, bakers, brewers and food manufacturers, both domestically and internationally.

Canada Western Red Spring Wheat – Harvest Quality Report – November 12, 2014

The Canadian Grain Commission (CGC) continues to release updated information in its Harvest Quality Report of Canada Western Red Spring Wheat every Tuesday.  To date in Manitoba, 39% of the samples analyzed are grading in the top two grades, holding constant from the November 4th report (see Tables 1 and 2).  Overall average protein content remains at 13.5%.  According to the CGC, mildew is the most common downgrading factor in spring wheat this year.

  • All samples supplied by producers and grain companies.
  • Results are unlikely to represent samples harvested within two weeks of the date of this report (September 30th).
  • Protein content is determined by near-infrared measurements calibrated against the Combustion Nitrogen Analysis reference method and is expressed on an N x 5.7, 13.5% moisture basis.

Bruce Burnett of the CWB spoke at the CropTalk Westman webinar on October 1st where he presented the following graph showing long term CWRS quality in Western Canada. In 2014, about 75% of the crop was in the top two grades.

Check Your Grain Bins Before the New Year to Reduce Spoilage Issues

Most of the grain/oilseeds harvested in Manitoba in 2012 went into the bin very dry, but also very hot (>28C).  Good news for not having to dry the grain in fall, but that doesn’t mean you can forget about the potential risk of spoilage.  There are reports of grain deliveries in December 2012 being slightly heated, or having some other spoilage issues or insect damage.

 As we get colder, a convection cycle starts in the bin, moving the humidity from the  cooling grain downward, into the bin centre and then up to the top of the bin.  During the process, two things can happen that causes spoilage issues. First, at the top of the bin, moisture can condense and accumulate, creating an ideal zone for spoilage and crusting. Second, grain is an insulator and the ‘bin heart’ that is warm with moist air moving in, can continue to heat, forming ‘hotspots’ of heated grain and/or creating ideal conditions for insects.

To avoid this unpleasant discovery, go check the bins before the New Year.  Routine monitoring for symptoms of spoilage (smell, visual signs), checking grain temperature and moisture will help manage the stored grain quality. 

  • Watch for bins that the snow has melted off.
  • Open hatch to check inside. Grain/oilseeds should not smell musty, mouldy or sour and should not have any white or greyish crusting. 
  • Probe the core of the bin and the probe should penetrate the grain easily.  If not, a crust could be forming underneath the top layer of grain or a heated/dense spot may have occurred.

 The practise of taking ‘a load’ out of the bottom of the bin and putting it on top or ‘turning’ the bin is also helpful in moving the layers of grain around in the bin and fracturing the heart to reduce pockets of hot and moist grain.
