Variable rate nitrogen: What are we trying to accomplish?
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.
