Spray experts say knowledge of inversions could prevent drift events


FarmTech is a great place to run into people you know and to meet people who you should know. A regular here on RealAgriculture, Tom Wolf, spray guru at Sprayers 101, brought along his friend Dr. Jim Wilson to FarmTech this year. Wilson previously worked for South Dakota State University as the extension pesticide education coordinator.

The pair join RealAg Radio host, Shaun Haney, to discuss temperature inversions: What they are, and why a producer should be concerned about inversions when they move their sprayers to the field.

Wilson points out that inversions are one of those things people don’t think about, but really should as it could be dangerous if you don’t take specific weather conditions into account. Wolf adds that inversions are quite a challenging concept to understand and anticipate, and, in Canada, we don’t have the technology set up like they do down in the United States.

In North Dakota and South Dakota, they have automated weather stations that take into account wind speed, temperature, soil temperature, solar radiation, and most recently added a second temperature centre, one at about one meter off ground level and the other at three meters, which, according to Wilson, will give farmers a forecast if there’s a temperature inversion at that specific location.

Listen to the full interview with RealAg Radio host, Shaun Haney along with Tom Wolf of Sprayers 101 and Dr. Jim Wilson of South Dakota State University.
