Nitrogen credit contribution by alfalfa to corn

Craig Sheaffer, George Rehm, and Paul Peterson, University of Minnesota

Alfalfa is well known for enhancing yield of grass crops like corn that follow it in rotation. Alfalfa benefits are due not only to the addition of biologically fixed nitrogen (N), but also to rotation effects including reduced disease and weed pressure and increased soil organic matter and aggregation of soil particles. Taking advantage of alfalfa's rotational benefits reduces fertilizer and pesticide costs and boosts yields.

A review of the 2004 growing season and corn hybrid maturities for 2005 in southern Minnesota

D.R. Hicks, Agronomy and Plant Genetics

The cold and wet growing season for Minnesota delayed the growth and development of corn such that growers may consider selecting earlier maturing hybrids for 2005 compared with maturities that they have normally been growing. The subject of this newsletter is to evaluate the yield and drying cost tradeoffs of planting earlier maturing corn hybrids.
