Starter Fertilizer and High Yield Management Impacts on Corn Production.

As corn yield levels continue to increase and profit margins decrease, producers are interested in learning how starter fertilizer composition and high yield management practices impact corn production on soils testing high in P and K. Plot were established at six site-years over four growing seasons on silt loam soils in southern Wisconsin. Treatments included the evaluation of starter fertilizer component (N, P, K, Mn, Zn, and B) and high yield management practices (higher seeding rate, higher sidedress N fertilizer rate).
