Three questions on storage risks canola growers may face during harvest 2023 – hot seed, lots of chaff and high chlorophyll counts.

1. Canola binned hot can spoil even if moisture is 10% or “dry”. What is the recommended safe maximum temperature for long-term storage? 

25°C

20°C

15°C

10°C

2. Under what scenario can green content in canola seeds be reduced after swathing (and before combining)? 

It can’t. Green seed is locked in after swathing

Warm temperatures and seed moisture above 20%

Cool temperatures (less than 10°C) will trigger green removal

Green percentage is related to moisture: Lower moisture is lower green

3. Concentrated areas of chaff can be a start point for spoilage, even in a bin where the seeds test dry. The risk from high-moisture dockage tends to be higher in what situation?

Straight-combined canola

Swathed canola
