In this video, Dr. Neil Hansen, Brigham Young University, talks about how they co-locate both soil moisture sensors and water potential sensors in row crops to increase quality and yield and reduce nutrient leaching, disease, and irrigation costs (pumping costs).

Transcript:
So with center pivot sprinklers, which are one of the largest consumers of water globally. The technology currently is precise and uniform in the application of water across the field. Uniform irrigation is causing over irrigation in some areas and under irrigation and other areas. We are co-locating soil water content sensors and soil water potential sensors to understand the soil water retention properties. We look in real time in individual zones across the field to track current water content and prescribe irrigation rates as the pivot comes across the field. And we've been able to identify ways of reducing leaching, conserving water and maximizing the efficiency of the use of that water.
