Plan Now for Successful Corn Planting

By Jeff Coulter, Extension Corn Agronomist

Corn planting date studies from 1988 through 2003 conducted at the University of Minnesota Southwest Research and Outreach Center in Lamberton show that on average grain yield was maximized with an April 28 planting date, but planting dates ranging from April 21 to May 6 produced yields within 1% of the maximum (Figure 1). In central and northern Minnesota, optimum planting date windows generally begin a few days later. When corn planting is delayed beyond mid-May, yield potential is reduced rapidly.

Sulfur for Corn: 2010 and Beyond?

By: Daniel Kaiser, University of Minnesota Soil Fertility Extension Specialist
With spring almost upon us there have been questions regarding sulfur application for corn for the upcoming year.  Our current Minnesota recommendations focus on sulfur application to sandy soils that are low in organic matter.  This is mainly due to the fact that sulfate-sulfur is mobile and may leach out of the soil, and that the organic matter is a large storehouse of sulfur and through mineralization this sulfur can become available for uptake in plants.  In the past sulfur was added through atmospheric deposition, applied (but not accounted for) with other nutrients in some commercial fertilizer sources, and in animal manures.  Over time most of these indirect additions have lessened and it is reasonable to assume that there may be deficiencies showing up more prevalent today then in the past.  However, a large research focus has been placed on determining how widespread this problem is and if only cer…
