Winter seems to be sticking around. My thoughts and prayers have been with those of you calving with the difficult conditions this year.
I provided an update regarding soil moisture status in non-irrigated fields both in this week's UNL CropWatch at cropwatch.unl.edu and my blog at jenreesources.com. We'll see what happens with moisture in the next few weeks and I'll post updates to my blog.
Very few have tried planting in this part of the state that I know of. Grateful for all of you who keep me updated on what's going on through your questions and comments! In this week's UNL CropWatch, Roger Elmore took the lead on an article addressing corn planting. The message is to ideally wait till soil temperatures reach 50F with weather conditions allowing soil temperatures to remain at 50F or higher for the next 48 hours.
We've observed when seed was planted and a cold snap with cold rains was received within 48 hours, some problems with seed germination and emergence. Hybrids vary in cold tolerance and seed companies are a great resource for that information as to which hybrids could be planted first in colder soils. Soil temperature information can be found at the https://cropwatch.unl.edu/cropwatchsoiltemperature. We'd also
recommend you take the soil temperature in the field before you plant and can do so by using a meat thermometer.
Last year I remember receiving questions from April 21-24 regarding
planting corn and soybeans with an anticipated cold snap later that week. At that time, I was recommending growers switch to soybeans. The reason? Soybeans imbibe (uptake) water more quickly than corn seeds and while we hear 48 hours to be on the safe side, the critical period is more like 24 hours. Also, several years of both small plot
and on-farm research in Nebraska has shown the primary way to increase soybean yields is to plant early. Jim Specht's research showed soybeans produced a new node every 3.75 days once V1 occurs. The nodes are where pods and seed occur. Our on-farm research planting date studies also showed regardless if the spring was cold-wet or warm-dry, the early planted soybean always out-yielded the later planted with a total average across trials of 3 bu/ac. The data ranged from 1-10 bu/ac. We never planted early without using an insecticide or fungicide seed treatment to protect that seed, so we ecommend you add that if you do plant early.
Our recommendation would be to plant the last week of April or as close to May 1 as conditions allow. We've also seen good results after April 20 in years if the soil temperatures were around 50F with good weather conditions at least 24-48 hours after planting to maintain that soil temp. It's important to know your level of risk, though. Crop insurance planting date for replant considerations is April 25 and there may also be replant options from your seed suppliers. We never replanted any of our studies and I have only observed frost on soybean cotyledons one year where growers planted early with soybeans coming out of it. We had the largest number of acres I've seen planted by April 24 last year with thankfully no issues and they were able to take advantage of a high-yielding bean year. Perhaps this is something you wish to try for yourself this
year? Consider planting some passes of soybeans early and come back with some passes three weeks later. You can use this Soybean Planting Date Protocol if you're interested in trying this for yourself. Please let me know if you're interested in this!
Depending on the number of acres you have, some growers are now planting soybeans first. Others are planting corn and soybeans at the same time by either running two of their own planters-drills or custom hiring someone to plant soybeans for them. This also spreads risk and can help with harvest. Regarding maturities, a study conducted at UNL East Campus compared a 2.1 vs. 3.0 maturity group variety at 10 day intervals beginning April 23 through June 19. Yield was highest for early planted soybean and a yield penalty of 1/8 to 1/4 bu/ac per day
of delay in planting for MG2.1 and MG3.0 varieties, respectively was found. The study also indicated that yield of the MG3.0 variety was higher relative to the MG2.1 variety in early plantings (late April and early-mid May), but the opposite (greater yield in MG2.1 versus MG3.0 variety) was found for late plantings (late-May and June). In our part of the state, we've observed really high yields from strong
genetics in the MG2.4-2.5 varieties when planted early; so I have a hard time automatically recommending later MG varieties without more data. Thus, I would love to work with anyone interested in planting early comparing a high yielding MG2.4-2.5 vs. a high yielding MG3.0-3.5 to obtain more data. Here's a Soybean Maturity Group
Comparison with Early Planting protocol to consider and please let me know if you're interested in this!
Wheat: My colleague, Nathan Mueller in Dodge County, has taken the lead on Nebraska-Winter-Wheat-Regions. He's put together an excellent resource on his blog at http://croptechcafe.org/winterwheat/. Every Friday he's sharing an update called "What's up this Wheat." He also started an Eastern Nebraska wheat list-serv and his website explains how to subscribe to it. Grateful for his effort in this as we both have goals of increasing crop diversity in the areas we serve and there are many benefits to wheat in rotation!
Crabgrass prevention in lawns: Just a quick note that while our extension lawn calendars promote applying crabgrass preventer in mid-April, our horticulture experts say to wait until soil temperatures are 55F on a seven day average and we are currently far from that!

Letter to the
38th Legislative District
By Sen. John Kuehn,
Reliable and affordable access to the internet has become an essential need for most Nebraskans and is a common concern expressed by constituents in District 38. Many rural residents have significant challenges with speed and reliability of land-based internet service, and instead must turn to wireless providers to gain internet access. In fact, over half of internet access is currently via wireless devices rather than traditional computers connected to wired internet service providers.
Each generation of wireless technology brings with it a 10 fold increase in speed and capability. Increasing sophistication of applications and the sheer volume of data being exchanged during even basic tasks makes the deployment of the next generation of wireless infrastructure, known as 5G for 5th Generation, critical for rural Nebraskans.
This past week the Nebraska Legislature saw defeat of a bill critical to laying the foundation for deployment of 5G technology in Nebraska. Ironically, much of the opposition of the bill came from rural communities who would not be impacted directly by the bill's rovisions, but have the most to gain from a rapid upgrade to 5G technology.
The bill, LB 389, was written to provide consistency and facilitate the deployment of small cell technology in Nebraska's urban centers. If you have ever been at an arena or stadium in Omaha or Lincoln for an event and been unable to send a text or access the internet from your phone, you experienced the need for small cell deployment. A typical cell tower has a coverage radius of several miles. When use is high, such as when 10,000 people are in a single arena, the coverage area of a cell tower shrinks and congestion occurs. Small cell devices are placed on utility poles in areas of high density use to provide network access.
Currently cities have the ability to charge whatever they want for a wireless provider to lease space on a publicly owned pole to install a small cell unit. The city of Lincoln charges $2,000 annually for each device. That is a cost that is passed along to you, the wireless
consumer. For the governments of Lincoln and Omaha, these fees represent revenue streams that you experience no differently than a tax on your wireless bill. Each city also has its own process and restrictions for applying for placement. This patchwork of regulations and excessive cost has hindered the widespread installation of small cell technology in Nebraska's urban centers.
There are lots of things mounted on public utility poles. In Nebraska, these are poles owned by you, the ratepayer. The practice is so common hat NPPD has a set rate for leasing this space. It is $11.50 each year. The placement of small cell devices does not result in increased costs for the city. It does, however, provide an important consumer service to the taxpayers who own the infrastructure.
Small cell technology will never be deployed in the small towns across Nebraska. They are used only in situations where thousands of data users are concentrated in a very small area of a few city blocks. Despite this fact, many rural communities, including several in District 38, actively lobbied against the legislation with false claims. Unfortunately, their opposition has created serious consequence for rural Nebraskans. Nebraska now goes to the back of the line for 5G deployment, which delays the technology for several years.
With the increased speed and data transfer afforded by 5G technology, congestion in high density urban areas will be magnified. In order to accommodate the increased traffic, deployment of an extensive small cell network in Lincoln and Omaha will be required before upgrading Nebraska's cellular network to 5G. The barriers of cost and regulation established by cities to generate revenue has a very real and profound cost to all Nebraskans, beyond the increase on their cell phone bills.
Nebraska had an opportunity to streamline a regulatory process and facilitate better technology access at a lower cost, a process already adopted in 15 states almost unanimously. It highlights the need for voters to know clearly how their local elected officials are lobbying on legislative issues and the impacts of their efforts. Rural Nebraskans will be paying the price for years of the failure of their local officials to study and understand this very important issue.
