Ag Tire Talk: IF/VF vs. Standard Tire Technology

MAXAM:“The development of IF (increased flexion) and VF (very increased flexion) technology is allowing working air pressures to be lowered significantly delivering improved performance and better crop yields.”

BKT:“There are definite advantages in using IF/VF tires and applications where they work and perform much better than standard tires.”

YOKOHAMA OFF HIGHWAY TIRES AMERICA: “That’s because IF and VF Tires can help farmers reduce compaction force on their soils by 20 to 40%, or carry higher loads than conventional radials without increasing compaction.”

MICHELIN: “Independent studies conducted by Harper Adams University and University of Illinois, Urbana-Champaign, both concluded using Michelin (IF/VF) tires, at properly recommended field air pressures, will produce up to an additional 4.31% yield.

YOKOHAMA TWS:“How can tires with IF/VF Technology carry the same load with less air pressure? The answer is because the sidewalls have been redesigned to carry some of the load, whereas standard radial tires use the air pressure to carry the entire load.”

Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Video: Supplemental Nitrogen on Soybeans: Can Early Nitrogen Increase Yield?

Can supplemental nitrogen help soybeans reach higher yield potential? Technical Agronomist Tim Sickman walks through an ongoing trial at the Nutrien Innovation Farm in Owensboro, Kentucky, exploring whether a modest amount of nitrogen applied at planting can support higher-yielding soybean environments.

The trial compares 30 pounds of supplemental nitrogen across both 15- and 30-inch rows, along with treatments that include sulfur and micronutrients. Similar trials conducted in 2024 and 2025 delivered a six- to seven-bushel yield response, prompting the team to expand the research this season.

Early observations show that treated soybeans are slightly taller and averaging about two additional nodes on the main stem. These added nodes could create more opportunities for blooms and pods, but the true results will come at harvest when the team evaluates pod development, seed fill and final yield.
