1. Corn Nitrogen Rate Response Trials in Northwest and Westcentral Minnesota, 2007=-2009 With the growing number of corn producers and increased acres of corn in NW and WC Minnesota along with the revisions in the Univer sity of Minnesota Corn Nitrogen Guidelines (2006) many northern corn growers were asking a bout the validity of the new nitrogen guidelines for corn production in the region. Prior to 2007, University of Minnesota calibration and correlation data included in the new guidelines did not include any research sites north of Interstate 94. A request for funding from the ...

2. Dealing with Sulfur Deficincies in Crop Production: The Iowa Experience Research conducted for more than forty years (pri or to approximately 2005) in Iowa rarely noted improved crop yield with sulfur (S) fertilization. Studies during that time period with corn and soybean found yield increase from S fertilizer application only three times out of approximately 200 trials. Research in the early 1980's had also documented sufficient plant available S in the soil profile for crop production on most Iowa soil associations. Results of recent studies (2000- 2005) in corn ... Download paper
3. Effects of Sampling Time, Soil Moisture Content, and Extractant on Soil Test Potassium Levels An accurate prediction of plant-available pota ssium (K) requires a thorough understanding of the mechanisms that might impact soil test K. A three year field study was developed to determine relationships between soil test potassium (STK) levels and time of soil sampling, soil moisture content, and extractant. Five field sites were established in 2006 throughout Wisconsin at Arlington, Hancock, Marshfield, and Lancaster Agricultural Resear ch Stations, and a private farm in Fond du Lac county ...

4. Recommendation Development Under 4R Nutrient Stewardship The 4R Nutrient Stewardship concept defines the right source, rate, timing and placement of plant nutrients as those leadi ng to the economic, social and e nvironmental benefits desired by stakeholders. This implies roles for both science and stakeholder engagement . Scientific data on the linkages to outcomes needs to be communicat ed to stakeholders to ensure their valid participation and to build public confidence. Th e 4R Nutrient Stewardship concept helps to link science to practice and co... Download paper
5. Use of Nitrogen Mangaement Products and Practices to Enhance Yield and Nitrogen Use Efficiency in No-till Corn Long- term research has shown that nitrogen (N) fertilizer is usually needed to optimize corn production in Kansas. Research has also shown differences in the response to various N fertilizers, products, and practices , particularly in the eastern portion of the state, where soil and climatic conditions regularly can lead to N loss. A project was initiated in 2008 and continued in 2009 to quantify how a number of currently marketed products and commonly utilized management practices performed at... Download paper
