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.
What these cloud platforms aim to do is what we’re trying to call a virtual farm, where they’re really trying to recreate and do simulations of what could happen based on the data that you’ve got feeding in.
We're never going to get to the point, or we just aren't yet to the point where sensor technology is to where you don't have to soil sample. It's still a highly recommended practice that can really improve the quality of your nutrient management program.
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.
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.”
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, 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.
Streator, Ill., strip-tiller Larry Tombaugh took us into his farm “laboratory” to discuss some biological solutions he’s experimenting with on his corn and soybean operation, including Compost Tea, a biological soil stimulant which has 4,000 different strains of colony forming fungal units.
The 28th annual National No-Tillage Conference offers a mix of general sessions, No-Till Classrooms and invaluable No-Till Roundtables. Just as important is the chance to profit from unlimited hallway networking with the most innovative, forward-thinking minds in no-till during next January's event in St. Louis!
Kuhn Krause's focus, above all, is to continue to produce quality products to serve producers better; to strive to respond to their needs with new tools and new technology to meet their growing challenges. Agronomic practices are constantly changing, and at a faster pace now than ever.
