  2. Winter Application of Manure

    Author(s): Glen Arnold, CCA

    This past fall was particularly tough on livestock producers and commercial manure applicators trying to land apply livestock manure. Weather conditions were warmer and wetter than normal with the Ohio Agricultural Research and Development Center (OARDC) station at South Charleston recording 32 days with measurable rainfall totaling 9.91 inches in November and December. In these same two months the OARDC station at Hoytville recorded 24 days with measurable rainfall totaling 6.04 inches. The wet weather prevented many acres of cover crops being planted and has severely limited the number of days that field conditions were dry enough or frozen enough for manure application equipment to operate.

    A substantial number of livestock producers across the state will be looking to apply manure as soon as farm fields are frozen enough to support application equipment. Permitted farms are not allowed to apply manure in the winter unless it is an extreme emergency, and then movement to other suitable storage is usually the selected alternative. This article is for non-permitted livestock operations.

    In the Grand Lake St Marys watershed, the winter manure application ban from December 15th to March 1st is still in effect. Thus, no manure application would normally be allowed in January and February.

    In the Western Lake Erie Basin (WLEB) watershed, the application of manure to frozen and snow-covered soils require there to be a growing crop in the field. This could be a pasture, alfalfa, clover, ryegrass or a rape crop. There must be enough vegetation visible to provide 90% cover of residue and growing vegetation, Radishes and oats would not qualify as a growing crop as both are typically winter killed. Manure can be applied to fields without growing crops if the manure is incorporated at the time of application or incorporated within 24 hours of application.

    The rainfall rule for surface manure application in the WLEB is a weather forecast saying “not greater than a 50% chance of a half inch or more of rain in the next 24 hours”.  It is advisable to print out the weather forecast when you start applying manure so you have the needed proof if an unexpected storm drenches the area. is the most commonly accepted website for this forecast.

    Although not required by law, winter manure application should follow the NRCS 590 standards, which limit solid manure application amounts to five tons per acre and liquid manure application amounts to 5,000 gallons per acre. These have 200 foot setback distances from ditches, streams and creeks and must be on slopes of less than 6% and less than 20 acre areas in size without additional buffers.

    For liquid manure applicators, examine fields for tile blowouts, monitor tile outlets before, during, and after manure application and any other situations that might allow manure to reach surface waters.

  3. 2018 Northwest Ohio Corn Silage Test

    In 2018, 63 corn silage hybrids representing 16 commercial brands were evaluated in a joint trial with Michigan State University (MSU). One Ohio location is combined with Michigan's two southern (Zone 1) silage locations. The trials were divided into two maturity groups designated early and full season on the basis of the relative maturity (RM) submitted by the companies with results listed in separate tables.  The Ohio test site was located in our Northwest Region at Hoytville (Wood County). The two MSU sites were located in Branch and Lenawee counties, which are on the Ohio/Michigan state line.  The test results from the three 2018 locations are treated as one region. The plots were planted with 4-row Almaco SeedPro 360 plot planters and maintained by each respective state utilizing standard agronomic production practices. The center two rows were harvested using MSU’s New Holland T6.175 tractor which powered a two-row Champion C1200 Kemper forage harvester with a rear mounted Haldrup M-63 Weigh system.

    Silage tests were harvested uniformly as close to half milk line as possible. Near- Infrared Spectroscopy (NIRS) analysis was performed by MSU using their current procedures. Silage results present the percent dry matter of each hybrid plus green weight and dry weight as tons per acre. Other data presented include percent stand, the percentage of in vitro digestible dry matter, acid detergent fiber, neutral detergent fiber, neutral detergent fiber digestibility, crude protein and starch. Milk production in pounds per ton and pounds per acre were estimated using MILK2006 (UW-Madison Dairy Science Department).

    A complete summary of the Ohio results are available online at: More information on procedures and additional 2018 MSU silage test data can be viewed online at: For more information on Ohio State crop variety testing, visit:

  7. Coshocton and Muskingum County Extension for the 2019 Agronomy School!

    Featured presentations include…

    Grain Commodity Economics

    Corn and soybean prices could not have been more different from the start of 2018 to the end of 2018, as decreasing world stocks and growing demand provided positive outlooks in the first half of the year contrasted with global trade tensions and record U.S. production in the second half of the year. What price range can be expected in 2019 and what does that mean for Ohio producers?

    Farm Bill

    It only happens once in a 5 to 7 year span, but the U.S. Farm Bill included major implications for producers and sets the bedrock of farm risk management. Farm bills happen in two phases: the legislative phase where Congress writes and passes amendments to U.S. farm policy, and the implementation phase by government agencies like the Farm Service Agency and the Risk Management Agency. The legislative process is finished and assumptions can be made about the implementation phase and what that means for Ohio producers and federal risk management offered for agriculture the next five years.

    Manure Management

    Manure is a good source of nutrients, but like any fertilizer material it needs to be used appropriately.  This presentation will cover manure use within the context of a 4 R program and current regulations.   Determining an appropriate manure application rate involves soil testing, manure nutrient analysis, crop yield goals and manure spreader calibration.

    Weed Management

    Waterhemp continues to increase throughout Ohio and will cause growers to spend $5 to $30.00 more per acre to manage depending upon current practices.  Giant ragweed is also increasing in Ohio and forces the use of a preemergence herbicides followed by two postemergence herbicide applications.

    Corn Production…

    Get the most out of your corn input decisions and maximize an efficient use of nitrogen in your program.

  9. Conservation Tillage Club Breakfast Series

    Author(s): Mark Badertscher

    The 2019 Conservation Tillage Club breakfast program series will begin on Tuesday, January 8 at the Plaza Inn Restaurant in Mt. Victory.  Each session will start at 7:30 am with a complimentary buffet breakfast followed by the program at 8:00 am.  Other sessions will be held on January 22, February 5 and 19.

    On January 8, the program will feature Dr. Mark Loux, OSU Extension State Specialist in Weed Science speaking on No Pigweed Left Behind.  Western Ohio and other areas of the state have seen the recent spread of waterhemp and Palmer amaranth beginning to infest fields.  These pigweeds are currently resistant to three herbicide modes of action in Ohio and because they are genetically diverse, have the ability to become resistant to other chemicals in a short period of time.  Once they do, they become difficult and expensive to control and can rapidly decrease the profitability of a field.  The presentation at the Conservation Tillage Club breakfast will focus on how to prevent the spread of these weeds, as well as how to manage them once they do show their presence in a field.  Dr. Loux’s presentation will also address other resistant weeds that are difficult to control.

    The January 22 program will feature Bailey Elchinger, an INTL FC Stone, Risk Management Consultant with Grains.  Her presentation will focus on the 2019 Grain Marketing Outlook.  After experiencing a high yielding growing season this year with lower grain prices, farmers are looking for marketing tips to make the new year more profitable.  World events such as trade with China, changing weather patterns, production in other crop producing areas, and the abundant supply of grains have had an impact on the current markets.  Elchinger will discuss some of these events and how they could impact market projections for 2019.  Her presentation will also provide some insight about grain marketing options to consider and tools that producers might use to help reduce risk and gain better insight to help make better marketing decisions.

    February 5 Dr. Pierce Paul, OSU Extension State Specialist in Corn and Small Grain Diseases will speak to the Conservation Tillage Club about Corn Diseases.  Although the current crop season started out with few corn diseases, gray leaf spot and northern corn leaf blight did appear in some area corn fields.  Later in the growing season, some farmers experienced corn ear rots which had an impact on grain quality.  Dr. Paul will discuss these and other disease issues in corn production, providing recommendations for effective control.  Deciding when the disease reaches an economic threshold for fungicide treatment is only one factor to consider.  The other one is the window of opportunity to make application for best control.  Producers will learn about these topics as well as choosing a disease resistance package while selecting the best hybrid for a field will be part of this meeting’s message.

    The February 19 program will feature an interactive panel discussion of “Agriculture in 2030: A Look at Innovation through the Next Generation’s Eyes” presented by the Ridgemont FFA chapter.  The discussion will focus on changes seen by current farmers since they began their operations, today’s agricultural technology, and changes that are predicted for the future.  Topics may include artificial intelligence, crop production advances, 3-D printing of replacement parts, animal agriculture progression, greenhouse systems management, adult farmer education delivery, and the impact of alternative fuels.  Attendees to this breakfast meeting will be challenged to think outside of the box to consider the possible impact these future changes may have on current and future operations.

    The Conservation Tillage Club breakfast program series is jointly sponsored by OSU Extension and the Soil and Water Conservation Districts of Hardin, Logan, and Union Counties, and in cooperation with the USDA Natural Resources Conservation Service.  Contributions to meeting planning and presentation are being provided by the Ridgemont FFA.  Breakfast is courtesy of the generous support from agricultural lenders and agricultural businesses.  All events are open to the public and no advance registration is required.  Continuing education credits for Certified Crop Advisers is pending.
