Field Days feature Cost-Effective Management of Alfalfa-Corn Rotations

Field Days feature Cost-Effective Management of Alfalfa-Corn Rotations

U-M scientists to discuss studies conducted on 50 farms in Minnesota and Wisconsin over the last four years.

With today's high fertilizer and crop prices, adding too little or too much really affects the bottom line. Have you ever worried about how much nitrogen fertilizer your corn needs when it follows alfalfa? Or how the nitrogen credit from alfalfa to corn differs with soil type, weather, tillage system, or the condition of the terminated alfalfa?

Field Days feature Cost-Effective Management of Alfalfa-Corn Rotations

To discover the answers, the University of Minnesota and the USDA-Agricultural Research Service have conducted research on nearly 50 farms in Minnesota and Wisconsin over the past four years. This year, with funding from the Minnesota Corn Growers Association and the Minnesota Agricultural Fertilizer Research and Education Council, research is being conducted to compare nitrogen fertilizer rates and application timings for second-year corn after alfalfa, evaluate the pre-sidedress soil nitrate test, and improve the predictability of nitrogen credits from alfalfa to first- and second-year corn.

Results from these and related research projects will be presented at two upcoming on-farm field days near Lanesboro and Russell. Field days will include a plot tour and presentations on nutrient and agronomic management for alfalfa-corn rotations by researchers from University of Minnesota Extension.

These field days are free and open to the public. Refreshments and informational packets will be provided. There will also be a drawing for 'door prizes' which include alfalfa seed, thermoses, and coffee mugs.
