Corn Silage Trial Results Available

By Jeff Coulter, Extension Corn Agronomist

Results from the 2013 University of Minnesota corn silage performance trials are available at: http://www.maes.umn.edu/publications/field-crop-trials/corn

These trials were conducted across southeastern, central, and west-central Minnesota to provide unbiased and replicated information on the performance of numerous silage hybrids for growers and their advisors.

It is best to choose hybrids that perform well over multiple locations in a region. Consistent performance over multiple locations with different soil and weather conditions reduces risk because we cannot predict next year's growing conditions. A hybrid that performs well over multiple growing conditions in one year has a high potential for performing well in the same region during the next year.

Sauk Centre Hay Auction Summary Nov. 7, 2013

By Dan Martens, Extension Educator, Stearns-Benton-Morrison Counties

Here's my summary of the Sauk Centre Hay Auction on Nov. 7, 2013.

Lots sold are grouped here by bale type, kind of hay, alfalfa sorted in 25 RFV point groups, grass sorted based on protein. Straw and bedding materials are also listed.

Averages are calculated where it seems appropriate. Look at averages carefully where there are a few loads in a group; and where there is a wide range in price.

Management of Fields with Un-harvested Sugar beet Fall 2013 for Cropping Year 2014

John A. Lamb, Nutrient Management Extension Specialist

Because of weather, a number of acres of the 2013 sugar beet crop will not be harvested.  It has been a number of years (PIK years) since this many acres have been left un-harvested.  At that time, SMBSC and the University of Minnesota did conduct a number of research studies to answer the main production question:  "What should I do with these fields for next year?"

Nitrogen Crediting for fields with Cover Crops

By Daniel Kaiser, Fabian Fernandez, John Lamb, and Carl Rosen, University of Minnesota Extension Nutrient Management Specialists

The increase number of acres planted to cover crops has raised questions on nitrogen (N) crediting for the 2014 cropping year. While there are many benefits touted for the use of cover crops, there are a lot of unknowns when determining N credits. This is especially true for mixes with multiple plant species.

One of the benefits of cover crops is scavenging of N during the growing season. This N can potentially be released for the following year's crop. While there may be a benefit from additional N available to the next year's crop, the process of mineralization of N through the decomposition of residue can progress over the growing season. Thus, N may not be available during periods of rapid N uptake by corn. This delay in availability makes it difficult to predict the amount of available N using the total amount of N per acre contained in the crop. For small grain crops, if the crop was terminated when the crop was drying down, then no N credit should be used.
