Adding Bushels by Using Sensing as a Crop Protection Tool

By Dr. Ray Asebedo posted on May 14, 2019 | Posted in Crop Protection, Precision Agriculture

One area where Dr. Ray Asebedo sees potential is with crop protection. In one study, the end result revealed as much as a 40 bushel difference in corn yields — 220 to 260 bushels per acre — based on where fungicide was and wasn’t applied.

Applying ‘Agronomist Logic’ to Variable-Rate Recommendations

By Dr. Ray Asebedo posted on April 15, 2019 | Posted in Nutrient Management, Precision Agriculture

Dr. Ray Asebedo explains how agronomists working with no-tillers and strip-tillers can leverage collected sensor data to refine fertilizer prescriptions through what he calls the “agronomist nitrogen recommendation algorithm.”

Assessing Obstacles to Optical Sensing Adoption

By Dr. Ray Asebedo posted on March 12, 2019 | Posted in Soil Health

While the benefits of sensing technology are emerging, Dr. Ray Asebedo notes there are obstacles to more widespread use. In-the-field computing power and connectivity have been a limited factor.

The Science Behind Optical Sensing

By Dr. Ray Asebedo posted on February 18, 2019 | Posted in Soil Health

For an agronomist like Ray Asebedo, the science behind optical sensor technology starts with the premise that plants are visual communicators that “speak” in wavelengths of light. Lush greens are usually indicators of good health, a sign of enough N in the soil system. Yellowing can signal stress.
