Winter wheat growth stages are relatively normal at this point in the season; the crop may have looked a bit ahead in weeks past but conditions have been relatively cool. Wheat is in head throughout Southwestern Ontario and beginning to head in western/central Ontario.
Some winter wheat fields are looking yellow, even where nitrogen and sulphur have been applied. It is expected that in most cases there is still nitrogen available, but that wheat fields are under stress from sitting in wet conditions for an extended period of time. Leaching below the root zone can occur, especially on light soils, with significant precipitation. Transpiration by the wheat crop, however, has helped reduce downward water (and nitrate) movement. Significant nitrogen leaching is not expected to have occurred in most wheat fields. Read more
