What's VRT worth?
September 6, 2011
Studies explore economics and build a knowledge base toward best strategies.
Whether VRT pays or not depends largely on the specifics of the field, the knowledge that producers have available on that field and how well they use that knowledge to their advantage.
Watch speed to get best nozzle performance

Crop spraying is moving into the fast lane with today's new sprayers. But can nozzles keep up? It's time for a renewed focus on spray pressure to strike the right balance, says Dr. Tom Wolf.
Nozzles tips to consider for 2011

Some key innovations have flown under the radar that are worth a close look, says Brian Storozynsky.
Building a blueprint for better VRT

The key is developing a strong foundation of field and soil data, says Mike Bevans of AgTech Centre.
Proper mixing key to avoiding crop injury. Crop injury from pesticide residue often starts at the chemical mixing stage, says Emile deMilliano, manager of agronomic services with Viterra. "If I look at the situations I've seen in the field where we've seen improper tank cleanouts and injury to crops, it often starts with not doing a proper job of mixing the products. You have to ensure the product gets into solution."
Venturi nozzles only part of the equation, says specialist. "Although venturi nozzles have been known to cut spray drift by half, the fact is that you still can't spray into 25 to 30 mph winds just because you're using a venturi nozzle. There are still other factors to consider, and in today's farming environment, it pays to start thinking about them well in advance of spraying." – Brian Storozynsky, sprayer technology specialist, AgTech Centre, Lethbridge, Alberta.
