by Extension Educator Dan Martens, Stearns-Benton-Morrison Counties,, 320-968-5077

I have posted information for the August and September Sauk Centre Hay Auctions with the following links:

1. Aug 4 Summary - List of individual lots sold by groups based on type, bale and quality
2. Sept 1 Summary
3. Sept 15 Summary
4. History of Selected Lots October 2015 through September 2016
5. Graph of Selected Alfalfa hay groups.

The summer and September lines on the graph are drawn by hand, with number of loads noted. The vertical line for each sale represents the range of values, High, Average, Low.

Should soil health test results be used when determining fertilizer needs in Minnesota?

Print-friendly PDF (614 K)

Photo 1. Soil sampling Soil health and how to improve and maintain it has been a hot topic in agriculture recently. Soil tests, including the Haney Test, have been developed to help measure indicators of soil health such as microbial activity, the amount of carbon in the soil, and nutrient availability. As more farmers use soil health tests, the question arises if results from these tests can or should be used in determining fertilizer needs for crops like corn in Minnesota.
The importance of correlation and calibration
To help address this question, it is critical to recognize the importance of correlation and calibration in developing fertilizer recommendations. When soil is sent to a laboratory for analysis, specific procedures and extractants are used to determine the estimated availability of nutrients. Different extract…

Final corn yield forecasts and harvest considerations following excessive rainfall

by Jeff Coulter, Extension Corn Specialist
Final end-of-season forecasts of corn grain yield were recently made for several locations and states across the Corn Belt by University of Nebraska researchers. These forecasts suggest above-average yield for Minnesota and yields less than USDA’s forecasts for most other Corn Belt states.

Palmer Amaranth in MN: Reporting, preventing further infestation and monitoring

Photo: Bruce Potter Following yesterday’s confirmation of the presence of Palmer Amaranth (Amaranthus palmeri) in Yellow Medicine County, University of Minnesota Extension and the Minnesota Department of Agriculture (MDA) sent out a joint news release describing where this plant was detected, photos to assist in identification, the biological reasons why this weed is on the MDA’s Prohibited – Eradicate Noxious Weed list and why efforts to eradicate this weed are critical to Minnesota’s commodity crop producers.

Check pollinator plantings for Palmer amaranth

Yesterday Bruce Potter followed up on a crop consultant's request to investigate a newly established pollinator planting in Yellow Medicine County. The grower and consultant are to be commended for detecting and reporting this site during the establishment year.

Rye is Not Just a Cover Crop

Jochum Wiersma, Scotty Wells, and Axel Garcia y Garcia

Rye’s reputation in the US is built on its potential as cover crop. The allelophatic attributes of rye to suppress small seeded weeds are utilized in organic production systems while its drought tolerance and winter hardiness make fall establishment as a cover crop nearly fail-safe. Rye, however, is used in other parts of the world as both feed and food. Some of you may have had pumpernickel bread and if you are of Scandinavian descent you may have grown up with knäckebröd. As feed stuff, rye has some interesting properties that have grabbed the attention of hog producers in Denmark and Germany as a way to reduce antibiotic usage and stress in the group housing systems, both mandated by law.

Fall urea: Should I consider it?

Fabián G. Fernández, Daniel E. Kaiser, Jeffrey A. Vetsch
Crop harvest is around the corner and planning for the next growing season is in every farmer’s mind. One important decision is about when to apply nitrogen (N) and what source to use.

Remember these tips when baling corn residue

by Jodi DeJong-Hughes, Extension educator

Baled corn stalks While corn residue is incorporated or left on the soil surface in most fields, some producers harvest the residue for use as livestock feed and bedding. How much crop residue removal is too much? Soil productivity will be reduced if all of the corn residue in a field is removed and other sources of carbon are not added. Below are important factors to consider when determining which fields and how much residue can be removed while maintaining soil organic matter levels.

Updated corn yield forecasts and grain dry-down guidelines

by Jeff Coulter, Extension Corn Specialist
Corn in Minnesota is quickly approaching maturity (black layer) and silage harvest is well underway. Corn generally reaches maturity (black layer) at 55 to 60 days after tassels emerge. Stress to corn from dry conditions between now and maturity can reduce kernel weight, accelerate the arrival of maturity and dry-down of grain, and reduce stalk strength.
