Calibrate Your Combine Yield Monitors!

Calibrate Your Combine Yield Monitors!

By Anthony Bly

The equipment associated with precision farming is a considerable investment and is a great tool for gaining knowledge about your farming operation, soils, crop varieties and hybrids, fertility program and planting equipment. The yield monitor is often overlooked as the critical piece of equipment when the crops are ready for harvest. Just seeing the varying yields on the screen while combining across the field is not the whole reason for having a yield monitor. Without a properly calibrated grain yield monitor, the farm cannot successfully assess the true yield information to use in accurate decision making for managing soil variability and crop management. Proper calibration solidifies the investment made in the precision equipment. Harvest pressure is immense when the crop is ready, but a well-planned approach and proper calibration will help get the job done much more effectively. Don’t think that mistakes made during harvest or wrong yield data can be corrected after the fact. Basically, the old adage of “Junk in = Junk out” is very true!

What to include in your grain yield monitor calibration plan?

  • Make sure your monitor controller screen is ready for this year’s data. Is there enough room in the internal storage or the external USB. Move last year’s data to an appropriate folder or even get a new USB storage device for the upcoming year. Review the owner’s manual so you understand and re-fresh your memory of the calibration procedure.
  • Power up the yield monitor and components and make sure everything is working and there are no error codes that would indicate a potential problem. Check all the components and wiring to make sure everything is connected well and wires have not become damaged.
  • Verify the scale on your weigh wagon or grain cart is accurate. This may include loading out some of last year’s grain and checking the weight on a certified scale at your local grain elevator.
  • Think about a field you might want to start combining and develop a plan for how you will vary the grain flow across the mass flow sensor. Don’t use headlands, end rows and poor field areas. There are two ways to vary the flow across the sensor. One can vary the speed of the combine to increase or decrease the flow or keep the combine speed constant and vary the width of cut at the header or the number of rows for corn. With either approach, the larger the area combined for each calibration load the better. Your yield monitor manual will suggest the quantity of grain and number of calibration points to combine for each approach.
  • Understand that re-calibration is needed as grain moisture or test weights may vary by farm location and crop variety/hybrid. A rule of thumb is that different mass flow sensor calibrations are needed for grain above and below 20%.
  • Do not forget to calibrate the grain moisture sensor to values measured at your local grain elevator or your own moisture sensor if you know that it corresponds with a certified grain moisture tester.
  • Temperature and vibration calibrations are extremely important as well. As temperature changes during harvest one should make adjustments as needed. Vibration calibration usually are conducted with an empty machine running at full rpm with the header lowered to operational height.
  • Back up your data. When harvest is slow due of poor weather conditions, use this time to back up your data.
  • Always consult your manual or quick reference guides for your specific system. Many are available on-line and can be quickly downloaded to your mobile device.
  • A well calibrated yield monitor will help increase the value of all other precision farming equipment. The timeliness of harvest when the crop is ready is very critical, but making a right plan for calibrating the combine yield monitor before harvest is also equally (if not more) important. Doing it frequently or whenever time allows will definitely help understand how to manage the data not only for this year but also the subsequent years.

Happy harvesting and always think of safety first!

How a Desire to Lead Brought This Wheat Breeder to Canada

Video: How a Desire to Lead Brought This Wheat Breeder to Canada

Gurcharn Singh Brar is a wheat breeder whose path meandered from the breadbaskets of Punjab, India, to the sprawling fields of the Prairies. In a candid conversation, Brar shared insights into his journey, the challenges faced, and the undying passion that fuels his quest for better crops.

It all began with a childhood rooted in the wheat fields of Punjab, where agriculture isn’t just a livelihood but a way of life. His fascination with wheat and its potential led him to pursue a bachelor’s degree in agricultural sciences at Punjab Agricultural University. It was during this time that he encountered the spectre of rust diseases, particularly stripe rust, which plagued the region’s wheat crops. Determined to combat this menace, he set his sights on a journey that would take him across continents.

Venturing abroad for his graduate studies, he found himself in Saskatchewan at the Crop Development Centre (CDC), working under the mentorship of renowned researchers like Randy Kutcher and Pierre Hucl. Here, he delved deep into the world of wheat genetics, focusing on stripe rust resistance — a quest that would shape his academic pursuits for years to come.

After completing his master’s and Ph.D. in six and a half years, he embarked on a professional journey that would see him traverse academia and research. From brief stints as a research officer to landing his dream faculty position at the University of British Columbia’s Plant Science program, his career trajectory was marked by a strong drive to make a difference in the world of wheat.

Despite the allure of British Columbia’s unique agricultural landscape, he found himself wanting to return to the vast expanses of the Prairies, where wheat reigns supreme. He recently returned to the Prairies and is the new wheat breeder at the University of Alberta in Edmonton.

“The opportunity to lead an established wheat breeding program at the University of Alberta was a dream come true. With the necessary resources and infrastructure in place, I’m excited to drive innovation and develop high-yielding wheat varieties tailored to the unique conditions of northern Canada,” he says.

Brar, one of Seed World Canada‘s 2024 Next-Gen Leaders, has become known for identifying novel sources of resistance to priority diseases and his efforts in developing wheat germplasm with multiple disease-resistant traits.

In addition to his groundbreaking research, Brar is committed to mentoring the next generation of agricultural scientists.

“I believe in nurturing talent and empowering students to pursue their passions,” he says. “Watching my students grow and thrive in their research endeavours is hugely rewarding.”

As he looks ahead, Brar’s vision for the future of wheat breeding is clear: “My number one target is to develop high-yielding wheat varieties adapted to the northern climates of Canada. By focusing on early maturity and strong straw traits, we can maximize yield potential while ensuring resilience to environmental challenges.”

His decision to also join the Prairie Recommending Committee for Wheat, Rye, and Triticale (PGDC) executive as member-at-large came from a desire to play an even more important role in the world of Canadian cereals.
