There are multiple tools for farmers to work with when deciding Nitrogen recommendation rates. All of them operate on the spectrum between mechanistic and empirical approaches. In this episode of the Field, Lab, Earth podcast, Drs. Brian Arnall, Josh McGrath, and Wade Thomason discuss the key differences between these approaches, how they interact with accuracy and precision, how they intertwine with each other, future research for recommendation tools, and how farmers can best make decisions for their farms. Tune in to learn:

  • What the difference is between accuracy and precision
  • What the difference is between mechanistic and empirical approaches
  • How these approaches interface with Big Data and environmental concerns
  • What factors most impact which approaches farmers use
