William J. Wiebold has an extension/research appointment related to soybean and corn management. Extension objectives include the development of cropping systems that improve productivity, enhance stability, and protect the environment. He promotes grower acceptance of these cropping systems through educational programs targeting growers, input dealers, and regional extension specialists in Missouri. Research thrusts include studying the interrelationships among crop management choices (e.g. seeding rate, row spacing, planting date), no-tillage, grain composition and precision agriculture.
