Nutrient Management Planner for Minnesota software, version 4.0 for M.S. Windows 7 and Access 2010 is now available on a CD from UM Extension,, at the Extension Store. NMP helps producers and their advisors plan field-specific fertilizer and manure applications that meet crop needs and agency requirements. Recommendations are consistent with current University of Minnesota fertilizer recommendations, the USDA-NRCS-Minnesota 590 (Nutrient Management) Standard, and Minnesota State 7020 Feedlot Rules. The software generates reports that meet NRCS and MPCA requirements, and that serve producers' farm management needs. The software includes a farm nutrient supply and demand calculator to determine the acres needed for manure applications. NMP V 4.0 requires a computer with MS Windows 7 and MS Access 2010.

Sauk Centre Hay Auctions Sept. Oct. 2012

by Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties
   This is the first posting of my summaries of the Sauk Centre Hay Auction for the 2012-13 season. The first sale in September was the largest of 4 sales held now. It could be that buyers and sellers got busy with harvest after the first sale.
   Look at averages carefully, especially when they cover a small number of loads. Also take a close look a situations where there might be an odd load in the bunch. Large Round Alfalfa RFV 151-175 on October 18 is an example of this. There were 4 loads listed at $210 to $240 and one load listed at $40 per ton. Sometimes this is a load that is in poor physical condition, even though it tested in the range. Sometimes it is a data error. For me in this case, it doesn't make sense to include it in the average.
   I will list the postings here and some other sources of hay market information are listed in the extra reading.

History of Selected Lots 2012 2013.pdf  Average and Range of RFV and prices for Medium Square Alfalfa by 25 RFV points from 101 to 200 RFV for sales so far this year. Medium Square straw is also listed. This also lists season-long average and range values for each of the last 5 years.

Graph 2001 to 2013 SC Hay Auction.pdf   Line graph of markets for Medium Square Alfalfa groups from 2001 to present time. This year's line is Maroon. Dotted lines indicate where there were not any loads in the group at a sale. This graph starts with October sales; so there's not much on it yet for 2013

Corn Stalks 2010 to 2012.pdf  This is list of all the corn stalk sales during the 2010-11 sale season and 2011-12 season in a effort to get a more composite look at corn stalk prices. You can draw your own conclusions about whether it is useful.

In September, 2011, University of Minnesota Extension, partnered with NDSU Extension, brought you the Tires, Traction, and Compaction Field Day near Fergus Falls, MN. There are now four videos highlighting the key messages presented during the day. Each video takes you to the unique soil pits constructed for that day to illustrate soil structure and effects of equipment traffic on soils. Each video is under six minutes yet captures the field experience for those unable to attend. They represent a great refresher for the 200+ participants who were there.

Extension Educator - Nutrient Management

A new Manure Management and Air Quality Education website has been launched. The new website provides educational materials, and current research from the University of Minnesota, in the area of manure management and air quality in livestock production.

Major categories in the new website are: manure management, feedlot and manure storage, air quality, milk house wastewater, manure pathogens, manure treatment, and manure application.

The revised website includes the release of three major additions:

  • The long-standing UM Extension Bulletin "Manure Management in Minnesota" has been updated, printed, and posted on the web.

  • Results of 12 site-years of trials measuring corn yield response to time of swine manure application have been published as a research report entitled: "Swine manure application timing: Results of experiments in southern Minnesota."

  • Eight case studies of the economic and environmental response to using grid soil sampling to guide zonal manure application have been posted to the revised Manure Management and Air Quality website. These case studies will be presented in workshops this winter.

The website will also provide an events calendar with local and regional manure management educational opportunities.

This website was made possible by funding from the Minnesota Pollution Control Agency, Section 319 Nonpoint Source (NPS) Management Program from the United States Environmental Protection Agency.
