Seasonal Crop Summary
August 26, 2025
Northwest Region
Precipitation in some parts of the region slowed harvest progress. Pre-harvest applications continue as stages are reached and conditions allow.
Winter cereal harvest moves closer to completion in the Swan Valley region, while other areas are nicely underway. Spring wheat is mostly in the hard dough stage and harvest has started across the region. Early yield estimates are 50 to 60 bu/acre with some fields yielding higher.
Field pea harvest continues across the region. Yields range from 30 to 60 bu/acre.
Canola continues to be varied across the region. Most fields are podded and moving towards maturity. Desiccation and swathing have started. Varied stages within some fields is noticeable, where some plants are mature and some are still flowering. This is especially noticeable in areas where parts of the field germinated late due to a lack of spring moisture.
Soybeans are in the R5 to R6 stage, and range in conditions. Some crops have benefited from recent precipitation, while others continue to show lack of moisture symptoms.
