It’s early morning on a bright, clear day. The sun is just starting to climb. There’s a heavy dew on the crop. Should you still head out to spray? Well, the dew is one thing, but there’s a much larger factor at play here that should factor in your decision. Whether or not you should spray with a heavy dew on the plant is this week’s Question of the Day, and then it’s time to head into the meat of this — inversions.

The concept of an atmospheric inversion isn’t the most simple thing to wrap your head around, but in this episode of Spray Tips, Tom Wolf explains it, draws it and describes how to manage for it. What more could you ask for? Well, for one, you could start asking the weather forecasters to include more information in the morning run-down to help you identify an inversion… but that’s a discussion for another day.
