Variable maturity within fields has been an issue all season in many regions so as combines begin the harvest it is important to take a good, representative sample (not just the edge of a field) to know what the entire field is like. Field edges are often more ripe than other parts of the field. When starting to combine, take a sample of an area that represents the majority of the field (including low spots, late maturing spots, etc.). This will help ensure you know the characteristics (moisture, green seed percentage) of the canola you are binning from the entire field.
