Active sensors & variable rate nitrogen: What MN farmers should know

Brad Carlson and Jeff Vetsch talk about variable rate sensors on today's Advancing Nitrogen Smart Podcast episode. What is meant by the term 'active sensors' and what data do active sensors capture? Which specific brands of sensors have the Southern Research and Outreach Center (SROC) researched, and how did they perform? What stage does corn need to reach before sensors can best contribute to variable rate decision making? How do other field variables like soil texture or irrigation systems contribute (or not) to variable rate sensing? Join us today for part one of a two-part discussion on variable rate technology with Brad and Jeff.
