On this episode of Advancing Nitrogen Smart, Brad and Dan take some of the mystery out of variable rate N. What are we trying to accomplish when we use a variable rate management practice? What kinds of field conditions might benefit from VRN, and which conditions should be avoided with VRN? How might the other 3 R's (Timing, Source & Placement) play a part in rate decision making? All that and more on today's show.
