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.

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.

Dr. Ray Asebedo discusses the need for assessing phosphorus and potassium levels through proper sampling techniques.

Dr. Ray Asebedo, former assistant professor of precision agriculture at Kansas State University and consultant for Topcon Agriculture, discusses the motivation behind the momentum for optical sensing technology in strip-till.

Dr. Ray Asebedo is a former assistant professor of precision agriculture at Kansas State University and consultant for Topcon Agriculture. He focuses on the development of agronomic algorithms and IoT to enable farmers to utilize optical sensor technologies for nutrient management in corn, soybeans and wheat.
