More than 90 farmers from across the country joined Farm Journal Field Agronomists Ken Ferrie and Missy Bauer for the Corn College Short Course at Ag Connect Expo.
Farm Journal Associate Field Agronomist Missy Bauer gave a lesson in zone management and how to farm by the foot. To respect soil types and water holding capacities of soil, Bauer stressed the importance to breaking out of the squares of grid sampling to shift toward zone management. Bauer says there are multiple tools to help understand yield zones, including:
· Yield maps, from a well-calibrated yield monitor
· NDVI imagery
· Soil test
· Mapping using tools such as those from Veris technologies
To build on the approach of zone management, Farm Journal Field Agronomist Ken Ferrie layered on information about lime and soil pH. Ferrie encouraged farmers to look closely at their soil tests to evaluate their lime application decisions. He also noted to be a steward of the soil to maintain soil structure—soil structure can’t be rebuilt in a single year. It can take multiple years and intensive management to build back soil structure.
Then Ferrie switched gears and provided some of his know-how for nitrogen application and management. Ferrie gave the details on ammonia, urea, ammonium nitrate and ammonium sulfate, and he provided the applications for each to maximize yields.
