Characterizing Nitrogen Fertilizer Use on Manured Fields in the SE Karst Region
M.L. 2009: (c) $375,000 the first year and $750,000 the second year are to increase groundwater and drinking water protection from agricultural chemicals, primarily nutrients.
The MDA partnered with the USDA National Agricultural Statistic Service (NASS) and University of Minnesota researchers to collect information about fertilizer use and farm management. Surveys were conducted over the phone. NASS staff are highly skilled at obtaining critical information over the phone with minimal time and burden on the producer.In 2011, the survey focused on the southeast region of Minnesota. The survey was designed to gather information about nitrogen fertilizer rates, timing of nitrogen application and use of nitrogen inhibitors. The survey was also designed to collect information about manure applications including livestock type, rate and incorporation of manure. Similar surveys were used to collect information about pesticide and fertilizer use by farmers in different areas of the state. In total, MDA supported three surveys in fiscal year 2011.Information collected in the survey is highly beneficial for:Guiding future educational and research programsGauging the effectiveness of implementation programsUnderstanding trends in fertilizer use efficiency Results of this project are included in a larger statewide report: Fertilizer and Manure Selection and Management Practices Associated with Minnesota's 2010 Corn and Wheat Production (PDF: 5.24 MB / 193 pages)
