WHAT A FALL!!! According to the November 26 Crop Weather Report, approximately 14% of corn and 10% of beans still in the field. The average moisture content of corn harvested last week was 17 percent and the average for soybeans was 16 percent, how big of a concern is this?
The weather continues to be unpredictable and give challenges to operators with grain and crops still in the field. Snow and ice over the last couple weeks have just been the latest in a long list of hurdles that growers have had to overcome this season. With some careful thought and planning you can still have a successfully harvest.
Having corn in the field now can be a double-edged sword. The longer it stays out, the dryer the corn will be when harvested, thus decreasing your drying costs. However, there is a higher risk of yield loss the longer the corn stays unharvested. Research on winter corn drydown showed that over a five-year span, corn grain would lose roughly 40% of its moisture between the months of October and December, when left in the field. The tradeoff is that we cannot anticipate the weather. The same study found that a single year yield decreased by 45% and another year decreased by only 5%.
Another concern of unharvested corn could be disease and mold. When discussing disease and mold, snow and ice pose no more danger to your crop than rain does. A positive of this situation is that the lower temperatures could have a limiting effect on pathogens’ ability to incubate or develop. A drawback of having laying snow is an increased opportunity for lodging. This year we have already seen a lot of lodging due to stem rots and adding snow to the mix may increase this risk. The risk of lodging is even further increased when coupled with winter winds and snow and ice to come. The takeaway is that disease and mold issues should not be your largest concern right now.
If you have a large amount of stock rot and lodging, harvesting as soon as possible will be best for a successful harvest. If your corn crop has lodged, one thing to remember is that this is not a usual harvest. Special consideration and care must be taken to get acceptable yields, which means slowing down and using caution. A few other options you have for getting a better harvestable yield are combining in the opposite direction, or “against the grain.” This will allow the head to get under the crop and lift it up. Another option is to use a corn reel. A corn reel is a specialized piece of equipment that mounts on the top of your corn head and uses rotating hooks to lift the corn and allow the head to get under the lodged crop.
The last concern is compaction and rutting of fields … Who Doesn’t Have Compaction Issues This Year?? Compaction will linger for years and will require attention to avoid problems with next year’s crop.

Due to the cool and wet conditions, soybeans harvested at this time of the year will need to be dried on the farm or at the elevator. Some elevators will accept soybeans up to 18 percent moisture while others will reject loads that are above 15 percent moisture. Contact your elevator prior to delivery and understand their discount schedule. Information on understanding soybean discount schedules is available in “Understanding soybean discount schedules” from Michigan State University Extension.
Commodity soybeans used for domestic crush or export can be dried using supplemental heat. However, food grade and seed beans should not be dried with supplemental heat. Proper management is essential to minimizing damage when using supplemental heat. Keep the drying temperature below 120 degrees Fahrenheit.

Every elevator that receives soybeans has a discount schedule. Discount schedules are important because they communicate how and when various shrink factors and discounts are applied at delivery. Discount schedules vary from elevator to elevator and can be somewhat confusing. This article lists and explains the major shrink and discount factors pertaining to soybeans and provides examples of shrink and discount calculations.
Test weight is a measure of density (mass/volume) and is measured in pounds per bushel. The standard test weight of 60 pounds per bushel is always used to convert the scale weight of soybean loads to the number of bushels contained in the load. This is true even if the actual test weight of the load is lower than 60 pounds per bushel. Therefore, test weight does not impact the number of saleable bushels harvested from a defined area (acre or field). However, most grain buyers will begin discounting soybean loads when the test weight falls below 54 pounds per bushel. Discounts are applied to the gross weight of the load before shrink factors are applied. The only advantage of having test weights higher than 54 pounds per bushel is that the beans will take up less volume in storage and during transportation.

Results from the 2018 Ohio Corn Performance Test are now available on line at: http://oardc.osu.edu/corntrials
Single and multi-year agronomic data is currently available for the Southwest / West Central and North Central / Northeast regions. Upper Sandusky will be harvested when field conditions allow. Results for Upper Sandusky and the Northwest region summary will be updated immediately after harvest. The results can be accessed by following the links on the left side of the page. Information regarding the growing season, evaluation procedures and traits will be available soon. Additional hybrids will be added as soon as marketing information becomes available, as will the combined regional tables (which are especially helpful in assessing hybrid performance across locations).

Yield results from all three regions (north, central, and south) are now available online as a pdf at: https://stepupsoy.osu.edu/soybean-production/variety-selection/ohio-soybean-performance-trial Grain quality results and sortable tables will be available in November.
Average yield for the Ohio Soybean Performance Trials by location and trial (early and late) for 2017 and 2018 is shown in the table below. Soybean yield in the north region (Henry and Sandusky County) was much greater in 2018 compared to 2017. (Yield from Henry County was not reported in 2017 due to extremely wet weather causing yield to be variable.) In the central region, soybeans in the early trial yielded greater in 2018 compared to 2018. However, in the late trial, soybean yield slightly decreased in 2018 compared to 2017. Yield in the south region was variable with Preble County yielding less in 2018 compared to 2017 while Clinton County yielded greater in 2018.

The weather pattern will support wet weather into the middle of November with a series of storms now every several days. With clay type soils and reduced evaporation this could lead to standing water in fields in the next few weeks. We expect a wet weather system for the middle of this week followed by another next week.
November will be marked with above normal rainfall and temperatures trending from near normal to above or much above normal for the second half of the month.
Rainfall for the next two weeks will average 2-4 inches across the state with isolated higher totals in the south and east sections. A few spots in the northwest sections may be below 2 inches. This is above normal in all areas of the state though and much above normal in eastern and southern sections. See attached graphic for the two week rainfall outlook from NOAA/NWS/OHRFC.
The pattern remains in place with overall wetter conditions into December (though the second half of November may dry out some). It still appears January into February and possibly March will experience normal or slightly below normal rainfall before more wet weather returns sometime in April of 2019.
Much of the state has seen freeze conditions already with only pockets of the state not seeing a freeze yet (like near Lake Erie in northeast Ohio). However, much of the state has not seen a hard freeze yet (though parts of Northwest Ohio have). There is a chance we will go well into November before we see a hard freeze widespread across the state of Ohio.
OK, While many of us feel that this picture represents how harvest has gone so far, we are not really that far behind. The most recent Ohio Crop Weather report issued on October 9 shows corn harvest at 21%. At this time last year we had harvested 12% of our corn while the most recent 5-year average is 17%.
Soybeans are lagging behind just a bit. This report shows Ohio bean harvest at 30%. This compares to 42% last year and a 5-year average of 36%.
So why do we feel we are so far behind? Probably because we started sooner this year and have received just enough rain to prevent us from running beans many days this year. Early reports that I am hearing have soybean yields much better than last year and good corn yields as well.
