Spring Weather & Soil Conditions: Update 4

By Aaron Wilson

Soil Temperatures and Moisture

Cooler weather remained in place this past week with temperatures running 2-6°F below average. Overall, daily average soil temperatures are slightly warmer than they were last week (Figure 1). Northern locations are hovering in the low 50s, with southern stations reporting mid- to upper 50s.

Precipitation was heaviest across portions western and southeastern Ohio, where 1-2” fell (Figure 1). Isolated heavier amounts greater than 2” were observed across central and west central Ohio (see CoCoRaHS). Soils moisture remain adequate to damp across the state, with this week’s rain helping to curb drying trends experienced over the last 30 days. Much of the state is reporting soil moisture between the 30th and 70th percentile compared to historical conditions (Figure 2-right).

Weather Forecast

This week is starting out with a rather raw weather pattern, with low pressure located to the north of the state providing stiff westerly winds, periods of rain/snow showers, and highs only in the 40s. These conditions will persist through Tuesday in the west and into Wednesday morning in the east until high pressure starts to wield its influence later in the week. After a cold and possibly frosty start to the day on Thursday, sunshine and southerly flow will help elevate highs back into the 60s, with some 70s showing up over the weekend. Except for a slight chance of a passing shower in the southwest on Friday, the period Thursday through Sunday should remain dry before precipitation could move in next Monday. Overall, precipitation will be light this week with the Weather Prediction Center currently forecasting 0.25-0.75” for much of Ohio and slightly higher amounts possible across the northeast (Figure 3).

The 6-10 day outlook from the Climate Prediction Center and the 16-Day Rainfall Outlook from NOAA/NWS/Ohio River Forecast Center show temperatures leaning toward warmer than average with near normal precipitation (Figure 4). Climate averages include a high-temperature range of 68-73°F, a low-temperature range of 47-52°F, and weekly total precipitation of about 0.85-1.15”.

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.
