1. Zone Delineation for Nitrogen ManagementManaging nitrogen through zone soil sampling has been shown effective in revealing residual soil nitrate patterns in North Dakota. Zone delineation has been constructed using several types of data, including yield maps, remote imagery, topography and soil EC sensor data. A study was conducted in North Dakota, Montana and Minnesota to evaluate zone delineation methods. Across the region, yield frequency maps, topography, remote inlagery and soil EC data were effective in helping to construct zones.... |
2. Corn Nitrogen Rate Response Trials in Northwest and Westcentral Minnesota, 2007=-2009With 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 Minnesota... |
3. The Manitoba Greenhouse Gas Assessment ToolMethane (CH4) and nitrous oxide (N2O) are potent greenhouse gases (GHGs) emitted by agriculture. Manitoba Agriculture has developed an educational GHG assessment tool that allows farmers to evaluate annual emissions of these GHGs from their practices and explore the impact of changing practices. The first phase of the GHG assessment tool consists of annual estimates of N2O and CH4 emissions from soil and crop management practices, livestock... P. Loro, M. Riekman, C. Sawka |
