EARLY SPRING

Applying Some Starter N at Seeding Critical in Spring Wheat and Canola Drs. G. Lafond, S. Brandt, W. May, C. Grant, A. Johnston Canadian researchers speculate that 50 percent of total N required should be applied at seeding to minimize risks with postemergent N applications. (PDF, 2 pages, 54 KB)

Starters Bump Corn Yields 17 bu/A Versus No-Starter Controls Dr. Gyles Randall and Jeff Vetsch Minnesota 2004 study showed that yields tended to be greater when sulfur was included in the starter in a wet, cool year. (PDF, 3 pages, 63 KB)

When Banding Near the Seed, Be Careful! Drs. George Rehm, John Lamb, Mark Bredehoeft Best if there is a small amount of soil between the seed and fertilizer. (PDF, 2 pages, 90 KB)

Late-season Applied N Can Increase Alfalfa Yields Drs. W. Raun, G. Johnson, S. Phillips, W. Thomason, Mr. J. Dennis, Mr. D. Cossey Increased yields due to applied N found in last or second to last harvest. (PDF, 3 pages, 70 KB)

SPRING

Returns Mixed On Wheat Pasture Response To N and Maintenance P in Wheat/Stocker Systems J. Sij, W. Pinchak, J. Ott, B. Min, D. Malinowski, D. Robinson Even though yields were increased nearly 6 bu/A, a rough analysis shows returns were only marginally profitable. (PDF, 2 pages, 67 KB)
