Where did the week go? This sounds like I’m repeating myself. Monday we were able to harvest our Kenton Corn Response to Nitrogen plot. This plot is one of several statewide testing different nitrogen rates to provide data for updating the Tri-state Fertilizer Recommendations. This particular plot was a no-till field and a typical Hardin County mineral soil in a township that was drought stressed. Nitrogen rates applied were 100, 150, 200, 250 and a 0 lbs N per acre check strip that were side dressed with 28% UAN. These treatments were replicated three times across the field. Yields were between 67.5 and 153.9 bushels per acre with moisture from 18.3% to 19.7%. A big thanks goes out to Jerry and Bob McBride for cooperating with this fertility trial. Once all the data is summarized, it will be made available with other on-farm research reports at agcrops.osu.edu.
Our Conservation Tillage Club breakfast meeting committee met Monday morning and began planning this winter’s programs. We selected January 10, 24 and February 7, 21 with topics of Grain Marketing Outlook, Weed Control, Precision Agriculture, and Soil Health. If we are unable to get a speaker lined up for one of these topics, Corn Diseases was our alternate topic. Watch for more information on this winter’s Conservation Tillage Club breakfast meetings as we get closer to January.
This year there were some soybean quality issues caused by disease, weeds, and insects that were present in several fields around the area. I have included an article about these issues that is attached to this email. Even with these quality issues, many of the farmers I have talked with have been pleased with this year’s soybean crop. There are still a few soybean fields out there to be harvested, but for the most part, soybean harvest is nearly completed in Hardin County. Upcoming local events include Ag Council on Friday, November 4 starting at 7:00 am at Henry’s Restaurant and the Hardin County Fairboard is meeting Saturday, November 5 starting at 7:30 pm at the fair office. Voting for Hardin County Ag Society (Fairboard) Directors will be the same day from 3:00-7:00 pm at the fair office. I have included some agronomy articles below that you may be interested in reading.
November Weather Outlook – Jim Noel
The outlook for November calls for temperatures and rainfall above normal. It appears we will see a series of weak weather systems the next two weeks. Most of the state will be at or below normal rainfall into the start of November. However, the far northern tier of Ohio will see normal to above normal rainfall putting pressure on wet conditions and challenge harvest in the far north and northeast part of the state. After a start to November not really wet except far north, most climate models indicate a return to a more active weather pattern for middle and later November. Along with the wetter pattern will come temperatures several degrees above normal.

2017 On-Farm Fertilizer Trials for Corn, Soybean, and Wheat – Steve Culman, Greg LaBarge, Harold D. Watters, Ed Lentz, Anthony Fulford
Ohio State is looking for farmer cooperators and crop consultants to help conduct on-farm field trials for the 2017 field season. The 2017 field season will likely be our last year of field trials before Ohio fertilizer recommendations are updated and/or revised. Updating fertilizer recommendations is a major undertaking that will require a collective effort from numerous OSU extension personnel, crop consultants and farmer cooperators. We are looking specifically at N, P, K and S in corn, soybean and wheat. We are collecting data from a large number of farms across the state and determine economically-optimum fertilization rates to maximize farmer profitability. These trials should be considered an opportunity to learn more about your farm’s fertility needs, but also contribute to a state-wide effort for better nutrient management and water quality outcomes.

Open letter regarding efficacy of Cry1F trait on western bean cutworm – Kelley Tilmon, Andy Michel
This open letter was prepared by the undersigned entomologists and extension educators regarding the efficacy of the Cry1F (Herculex 1, TC1507) trait on western bean cutworm (Striacosta albicosta). We strongly urge seed companies to remove the designation of “control” from this toxin with regard to this pest. At the time Cry1F received regulatory approval in 2001, western bean cutworm was found in the far western Corn Belt (Colorado, Idaho, Nebraska, and Wyoming), with occasional movement into western Iowa. Indeed, EPA’s original Biopesticide Registration Action Document (BRAD) for Cry1F Bt corn, published in August 2001, did not even mention western bean cutworm. Instead, the following language was used: “The registrant-submitted data indicate that Cry1F protected corn offers excellent control of European corn borer, southwestern corn borer, fall armyworm, black cutworm, and suppression for the corn earworm.” To read more about the efficacy of Cry1F on western bean cutworm, go to http://agcrops.osu.edu/newsletter/corn-newsletter/2016-33/open-letter-regarding-efficacy-cry1f-trait-western-bean-cutworm.
Prepare Your Sprayer for Storage Now to Avoid Costly Problems in the Spring – Erdal Ozkan
It is very likely that you will not be using your sprayer again until next spring. To avoid potential problems and save yourself from frustration and major headaches in the spring, it would be wise to give your sprayer a little bit of TLC (Tender Loving Care) this fall. Although this is a busy time of year, taking time to winterize your sprayer before temperatures fall below freezing will allow you to avoid issues such as cracked pumps, or pumps that cannot work at full capacity. Here are some important things you need to do with your sprayer this time of the year.

Forage Management Considerations After Frost – Rory Lewandowski
We have had some scattered frosts around the state that have generated some questions about forage use after a frost. The two most common questions concern the use of warm season grasses in the sorghum family and grazing alfalfa. The issue with grasses in the sorghum family, which includes sorghum-sudangrass hybrids, sudangrass and Johnsongrass in addition to sorghum, is that they contain cyanogenic glycosides and enzymes that convert those compounds to free cyanide (sometimes called Prussic acid) within their cells. Prussic acid or cyanide is a lethal toxin. Go to http://agcrops.osu.edu/newsletter/corn-newsletter/2016-36/forage-management-considerations-after-frost to finish reading this article.
