How to Use Yield Maps & Farmer Knowledge for Sensor Placement When placing moisture sensors, nothing beats local knowledge and historical yield data. In this video, Dr. Bryan Hopkins breaks down how he works with growers to identify key field zones—wet, dry, and average—and why long-term yield maps are the best backup when that knowledge isn’t available. By using a combination of experience and data, you can strategically place sensors to improve irrigation and maximize yields. See the case stud
