Seasonal Crop Summary
May 20, 2026
Northwest Region
A warm start to the week allowed for some seeding progress in the Northwest Region. The exception was The Pas where seeding has not yet begun due to wet conditions. Seeding progress was short lived as strong winds moved in Thursday/Friday, bringing rain, snowfall and cool temperatures over the weekend. The highest daytime temperature was reached at Ashville station early in the week at 27.8 degrees. The lowest overnight temperature was recorded at Keld station going down to -5.2 degrees. Most of the region experienced high winds Thursday into Friday with maximum speeds recorded at Ashville station at 80 km/hour. The entire region received precipitation this week, with the highest accumulated amount recorded at Minitonas weather station at 26 mm.
The Northwest region continues to need warm weather for field conditions to improve. Many fields are saturated with standing water in low areas. The southern portion of the region has seen more progress in field work and seeding. Seeding/fertilizing is more advanced in the Dauphin/Ste. Rose and Russell area while the rest of the region follows behind as conditions allow.
Soil temperatures remain cool. Weeds and volunteers started to grow quickly on the warm days and slowed over the weekend. Cool temperatures, delayed growth, and high winds have added to the challenge of spraying. Spring wheat seeding for the region is approximately 5% complete. Barley seeding has started in some areas. Field pea seeding is approximately 5% complete. Some soybeans have been seeded, with the approaching seeding deadline being kept in mind.
