The following chart shows the lowest average temperature that various crops will germinate at. While they will germinate at these temperatures, the above ground forecast and risk of frost must also be assessed when making a seeding decision.
These are the soil temperatures that our agronomist's have been finding over the past week. These were all taken on canola stubble around 9am at a 1.5 inch depth. In terms of soil temperatures, it's safe to say most crops are good to go with the exception of some large pulses!
