If you are looking for something to do, there are a lot of programs and events taking place in the next few weeks. Most of the nitrogen has been applied to the corn in the county, first cutting of hay has been made, and herbicide applications continue in area fields. According to the USDA, 100% of the corn is planted and 95% of the soybeans are planted in Ohio with 60% in good condition. I have attached the latest Ohio Crop Weather report to this email. Tonight (June 25) is ‘An Evening Garden Affair’ with Laura Akgerman discussing gardening with arthritis and disabilities. It will begin with a tour of the Friendship Gardens of Hardin County at 6:30, followed by her presentation at 7:00 pm in Harco Industries. See the attached news release and flyer for more information if you are planning to attend. Tomorrow evening (June 26) is the Ag Law program with OSU Extension’s Peggy Kirk Hall. She will discuss the ‘5 Property Laws that Farmers Need to Know.’ Her talk is scheduled to begin at 7:30 pm at the Burnison Barn, located at the Hardin County Fairgrounds. It will follow the Farm Bureau Summer Social, which is set to begin at 6:30 pm at the same location. For more details about this event, see the attached flyer.
The 2018 Ohio State University Manure Science Review is scheduled for Wednesday, July 25 at the Watkins farm located at 18361 Township Road 90, Forest, OH 45843 in Hardin County. The program will begin at 8:45 am, while registration, coffee and donuts will be offered in the morning starting at 8:15 am before the field day kicks off with the afternoon activities ending by 3:30 pm. There will be several guest speakers in the morning, lunch provided by Tim Holbrook, and field demonstrations in the afternoon. Make sure you check out the news release and flyer for registration and other information so you don’t miss this local field day geared towards our livestock producers and manure applicators. Registration is due by July 16 to take advantage of the $25 rate.
The Ohio Sheep Day is taking place July 14 at the OARDC Eastern Research Station with several educational topics to be addressed during this field day. See the attached flyer and contact Roger High, 614-246-8299, firstname.lastname@example.org if you are interested in attending this year’s event. The Western Ohio Precision Ag Field Day will be held July 16 near Versailles. Register by July 2 if you are interested in attending this year’s event. For more information, see the attached flyer as you won’t want to miss out on the nutrient placement discussion and field demonstrations. As you can see, there are several events planned for you to update your knowledge and skills, so make sure you take advantage of these opportunities. I have also included some agronomy articles below for you to read if you are interested. I hope to see you at one of these events in the near future.
Rest of June warmer than normal with high rainfall variability – Jim Noel
Not much has changed since last week in terms of the outlook. The rest of June is likely to be warmer than normal with high variability of rainfall but tendency to above normal rainfall. It appears a heat dome will be centered in the south central U.S. this summer with periods where it shifts over the corn and soybean belt and Ohio Valley. The next surge of heat will come this weekend into early next week. With these surges come a ring of fire of storms around the heat dome leading to locally heavy rainfall. However, that rain will be scattered in nature. To finish reading this article, go to https://agcrops.osu.edu/newsletter/corn-newsletter/2018-17/rest-june-warmer-normal-high-rainfall-variability.
Corn leaf striping often temporary – Steve Culman, Peter Thomison
Leaf striping (interveinal chlorosis) in corn is appearing in many Ohio fields. There are several nutrient deficiencies (including sulfur, zinc, magnesium, and manganese) that result in leaf striping and some of these look similar. The severity of the striping may vary considerably within a field and may be associated with differences in soil pH, organic matter, compaction, tillage, temperature and moisture. Bright yellow to white interveinal striping running the length of leaves may be the result of “genetic stripe”, but it’s usually limited to scattered plants within a field.

Wheat and Barley: Cool, Wet Late-Season Conditions – Pierce Paul
Cool weather and moisture after flowering often means extended grain-fill and high yields, especially when disease levels are as low as they were at the time of pollination and early grain development in some fields. However, excessive rainfall associated with the cool temperatures could increase the severity of diseases that thrive under cool conditions. But with the crop now well into grain-fill and even turning in some locations, there is very little you can do about late-season diseases. The pre-harvest interval for some of the best fungicides is 30-45 days, which mean that they are now off-label in most areas, given that harvest will likely begin in less than 30 days.

Diagnosing Soybean Seedling Issues in 2018 – Anne Dorrance, Kelley Tilmon, Laura Lindsey, Mark Loux
It seemed to take forever this spring, but hopefully all of your soybeans are planted – for the first and only time. Ohio’s biggest challenge is replanting; it is costly (new seed, cost of planting, lower yields due to delay in planting). The first step is assessing overall stand health – do you have enough plants to obtain the best yields? Based on a substantial amount of data, for soybeans planted in May, a harvest population of at least 100,000 plants/acre is generally adequate to maximize yield. Data from the Ag Crops Team on-farm trials indicate that a stand of 50,000 plants/acre only reduced yield by 15% compared to a stand of 116,000 plants/acre (when planting in May). Soybeans have the ability to compensate for low populations by increasing the number of branches, nodes, and pods per plant.

Using PEAQ to Estimate Alfalfa NDF for Multiple Cuttings – Rory Lewandowski, Mark Sulc
Much of the region’s alfalfa crop has been harvested over the past two weeks. As cooler temperatures move into the area regrowth will likely slow down. Once regrowth reaches 16 inches tall again, the NDF (neutral detergent fiber crude protein) can rapidly be estimated in the field using the predictive equations for alfalfa quality (PEAQ). Instructions on how to rapidly measure NDF in the field can be found at https://forages.osu.edu/sites/forages/files/imce/Estimate%20Alfalfa%20NDF.pdf. This in-field estimate can be useful for timing each of your subsequent harvests in different fields, based on your forage quality goals. It’s important to remember PEAQ NDF estimates are to be only used in standing pure alfalfa stands. PEAQ will not provide growers with an accurate representation of quality once the alfalfa has been cut, cured, and stored. After the forage is stored, samples should be sent to a lab to determine nutritive values for fitting the forage into a ration.
