Crop Update: This has been an interesting harvest season and yet, overall good one. To be at October 11th with so much of the area crop harvested is a blessing! I’ve heard growers thankful for the good harvest conditions and ability to go anywhere in fields without fear of getting stuck. Many were grateful for good soybean yields.
As we get further into corn harvest, there’s perhaps disappointment experienced on corn yields and moisture variance. Honestly, I’m struggling to explain some of it. Part of it is the difference in rainfall that we received in various parts of counties this year. There’s non-irrigated fields receiving 180-220 bu/ac which is a blessing! Another part is the impact of the July 8th wind event in which some fields had greater greensnap while others had more leaned plants. Depending on severity, was estimating and now seeing/hearing a lot of 180-240 bu/ac irrigated corn in those fields. The UNL Hybrid Maize model was predicting average yields for irrigated in this area of the State based on weather conditions. I just thought we may see actual yields go a little higher with how long it took to reach black layer. Have seen a couple really high yields with longer season numbers harvested wet.
Corn also greatly varies in moisture. Non-irrigated fields are quickly reaching 15.5% and lower. Irrigated fields range from 15-23%; what I can’t explain is that for hybrids planted in the same time-period, some short season ones are staying wet while some longer season ones are dryer. Everyone who has shared this situation with me had applied fungicide to their fields for southern rust control. Some also fertigated. Ultimately, just sharing what I’ve seen and heard thus far.
Received some questions this week on sampling for Soybean Cyst Nematode (SCN). It continues to be Nebraska’s top yield-limiting soybean disease with research showing it can cause up to 40% loss. The Nebraska Soybean Board is again sponsoring free sampling courtesy of soybean checkoff dollars. You don’t need a special bag to submit samples as a quart-sized plastic zip-top bag will suffice. If you had areas of a soybean field that yielded less than expected, particularly any areas that also showed sudden death syndrome or brown stem rot, consider taking a soil sample for SCN this fall. The female nematodes live in the top 8” of soil, thus sampling is as easy as taking your fertilizer sample for the following year’s corn crop and sending part of it in for an SCN analysis.
To collect a soil sample, use a soil probe to collect soil cores from a zig-zag pattern representing the lower yielding area of the field. For comparison, it’s wise to also take another sample from a better yielding area of a field. I’ve found that around 12 cores per sample is enough to provide around a 2 cup sample of soil that will fit in a ziplock type bag (and not have excess that needs to be dumped out). Be sure to label the bag with your contact info, field name, or other ID to report the results back to you. Also be sure to fill out a completed sample submission form requesting SCN analysis and mail the samples to the UNL Plant & Pest Diagnostic Clinic (1875 North 38th Street, 448 Plant Science Hall, Lincoln, NE 68583-0722). For those who submitted samples during the summer, campus mail is better now that the University campus is open again.
Caring for Drought-stressed trees/shrubs: With the continuing dry conditions, this is a critical time to prepare woody plants for winter and prevent winter injury, especially to evergreens. Dry fall conditions can reduce the number of leaves, blooms and fruits trees produce the next season. Trees often delay the appearance of drought-stress-sometimes months or years after the stress occurs. Even after the drought has ended, trees that experience drought stress are more susceptible to secondary attack by insect pests and disease problems, such as borers and canker diseases, which can cause tree death. When watering, moisten the soil around trees and shrubs, up to just beyond the dripline (outside edge of tree leaf/needle canopy), to a depth of 8 to 12”. Avoid overwatering; but continue to water until the ground freezes as long as dry conditions persist.
As I reflect, it was a hard week for many of you in our farming community with the weather and harvest delays. Many of us would say the challenges of 2019 actually started in the fall of 2018. From that perspective, it’s been an extra hard year! As we continue with a delayed harvest, I’m truly hoping the fall of 2019 doesn’t result in an extra challenging 2020 as well. I’m sure that’s a hope for us all!
It’s amazing how something as simple as the sun shining or incredible sunrises on then dreary, drizzly days lifted my spirits and the spirits of many of you I spoke or texted with this past week. For those who receive my email newsletter, you’ve seen me share each week a set of tips to consider for help in relieving stress/changing current mindset based on how much time you have in the day. And, some of you have rightfully put it back on me when I’ve needed a mindset change! While you may not want to take 30 minutes or even 10 minutes, we all have 2 minutes. So, my challenge for all of us is utilize one of the following tips for two minutes or use something else that works for you each day this week to change our mindset/lift our spirits when needed. Two minute tips (Adapted from: Gilbert Parra, PhD; Holly Hatton-Bowers, PhD, and Carrie Gottschalk, LMHP, MS): Breathe; Stretch; Laugh; Doodle; Acknowledge one of your accomplishments; Say no to a new responsibility; Look out the window (or go outside); (adapted) Faith based prayer.

Soybean Cyst Nematode (SCN) Sampling: With the increase in sudden death syndrome this year, several have asked for soybean cyst nematode sampling bags (as the two diseases are synergistic with each other). Free sampling is via the Nebraska Soybean Board through your soybean checkoff dollars. Sampling bags can be obtained from your local Extension Office or call 402-472-2559 to obtain bags. Crop consultants should contact Extension Plant Pathology directly (402-472-2559) for larger numbers of sample bags. Samples should be done for areas 40 acres or less (less is better). If you had areas with higher SDS this past year or places where yield maps showed lower yields, plan to take a sample from those areas of the field. Also take a sample from a good yielding area of your field for comparison. Take around 20 cores 6 to 8” deep. If you or an agronomist is taking soil samples, taking a few extra cores will allow for part of the sample to be sent in for fertilizer recommendations and the other part for SCN. Make sure to thoroughly mix the cores collected before transferring to sample bags. If you take them from a soybean field, taking the sample a few inches off the old soybean row may provide the highest potential numbers if SCN is present in the field. However, SCN samples can be taken from corn or sorghum fields as well to help inform decisions if rotating to soybean next year. Other places in fields which may first show SCN include: low areas where water drains after rain; along a stream that periodically floods; along fence lines; field entryways or driveways as that’s the first place equipment enters from other fields. Anything that moves soil will move SCN.
Lawn Weed Control: Now is an excellent time for weed control in lawns, especially for dandelions, clover, ground ivy, and plantain. This is because carbohydrates are being transferred to the roots of perennial weeds and thus allows for the chemical to move to the roots as well. If using granular products that contain weed killer, they’re best applied on mornings with heavy dew and no rain in the forecast for 24 hours (however, read the herbicide label). Most herbicides labeled for use around the yard will contain 2,4-D and/or dicamba. I’m often asked for names but this is not an exhaustive list and not intended to exclude anything available (2,4-D, dicamba, Weed B Gon, Trimec Plus, Trimec Classic).
