U of M SE Minnesota Regional Soybean Yield Results now Available

by Lisa Behnken, Fritz Breitenbach, Liz Stahl, and Ryan Miller

Performance comparisons of early (1.3-1.8) and late (1.9-2.4) maturity glyphosate tolerant/RoundUp Ready soybean in southeastern Minnesota are now available. The studies with 24 early-maturity and 25 late-maturity entries were conducted near Rochester, MN (Lawler site) on a Port Byron silt loam. Trials were planted on May 5, 2016 with a 4-row John Deere 7000 planter equipped with cone units. The seeding rate was 150,000 seeds per acre with seed planted at a depth of 1.5 inches in 30 inch rows. Plots were four rows wide by 22 feet in length and the center two rows of each plot were machine harvested on October 4, 2016.

Oct. 6 Sauk Centre Hay Auction Summary

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

I am attaching my summaries following the October 6, 2016 Sauk Centre Hay Auctions.

1. Oct 6 2016 Summary by groups based on type, bale and quality

2. History of Selected Lots

Shows Averages for each of last 6 years, including the 2015/2016 season. I left the 2010 year on because that’s how far back we go to find prices kind of similar to where we are now.

3. Graph of Selected Alfalfa hay groups.

The 2015/2016 line is hand-drawn yet for summer and fall auctions. I will start a fresh graph after the second October sale. The “vertical line” represents the range of values, High, Average, Low.

There may be some hay around that has been damaged by flooding. Some hay stored outside in some areas has endured a lot of rain. Averages with wide range of values, like $40 to $135 in the Medium Square RFV 151-175 range, may not mean so much. In the list of individual loads, all 6 loads averaged $107, and without the $40 load they averaged $121.

I encourage people to look at other sources of market information also. A couple are noted below.

New pictorial guide aids in Palmer amaranth and tall waterhemp identification

by Phyllis Bongard and Jeff Gunsolus

With the recent confirmation of Palmer amaranth in Minnesota, it is critical to identify this noxious weed, so it can be eradicated before it becomes widespread. A new pictorial guide compares key characteristics of Palmer amaranth and tall waterhemp at several growth stages throughout the growing season to aid in this identification.

Updates to the corn fertilizer guidelines

Daniel Kaiser and Fabian Fernandez
Extension Soil and Nutrient Management Specialists

A new update has been posted for the corn fertilizer guidelines in Minnesota. Throughout the fall we will be posting information regarding changes made to the guidelines as they pertain to nitrogen, phosphorus, potassium, and sulfur management for corn. For the first installment we will take the time to outline changes made to the nitrogen guidelines for the state of Minnesota.

A previous e-news was set out this spring outlining changes to the nitrogen rate guidelines for non-irrigated corn production. The revised publication was delayed due to questions that arose based on the suggested application rates of N for corn on corn. The new suggested rates are listed in Table 1 of the publication.

by Lizabeth Stahl, Extension Educator – Crops; Fabi├ín G. Fern├índez  and Daniel E. Kaiser, Extension Nutrient Management Specialists

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.

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.
