Wind-Hail Crop Damage Meeting

Recent wind and hail storms have created damage across our area counties in Nebraska and Kansas. This brief meeting to be held on Monday near Gladstone, NE is designed to answer farmers’ questions regarding harvest, crop insurance expectations, and what to expect regarding crop maturity and future damage.

Crop Update June 9

Corn that was hail-damaged on June 3rd is starting to regrow. Leaves wrapped up in the whorl are beginning to slough off as wind and warm temperatures cause the damaged tissue to die and break off. For more information on how stand loss impacts yield, please check http://cropwatch.unl.edu.

Some corn plants more severely affected were reduced to stems. Sometimes no new growth is appearing while in other plants new growth can be seen. I split open the stem on this plant since no new growth was apparent and the center looked discolored.

In this corn plant, a bacterial rot has set in as can be seen from the discoloration at the upper portion of this plant and the discoloration at crown area. This plant may not survive. This is typical of what we were seeing in Nuckolls/Thayer counties with the 8-10″ of rain they received there. My concerns for corn at this point are bacterial diseases such as this or Goss’ wilt that may continue to reduce stands through the season. Some growers are considering a fungicide application but fungicides don’t target bacterial diseases. We’d recommend anyone considering this to consider an on-farm research experiment and I’d be happy to help set this up for you.

These soybeans were reduced to stems yet are showing new growth 5 days later. UNL research has shown that soybean stands can be greatly reduced without a significant yield effect. Several growers are considering replanting; we’d recommend taking into account the research or conduct an on-farm research experiment to see any differences for yourself like this farmer did. The other thing we have looked for is bruising on stems and some flooded areas truly did not have plants survive. For more information, please check out http://cropwatch.unl.edu.
Nebraska’s Advantage
This week, I’d like to share some information that came out in a white paper from the UNL
Agricultural Economics Department on the special relationship we have here in Nebraska between crops, livestock, and biofuel production capacity not found in other parts of the U.S. to the extent we have here. It’s called the “Nebraska Advantage”.
I think it’s important for all of ag industry to realize we need each other as it seems we sometimes forget how inter-dependent we are. Crop producers need the livestock and ethanol industries as they are a high percentage of our end users. Yet many times I hear of crop producers fighting livestock expansion or livestock coming into an area. The purpose of the white paper was to share the numbers of where Nebraska livestock, grain production, and ethanol production currently stands, and what Nebraska could gain if we worked to increase livestock production in-state where we have a wealth of resources with our crops, water, and biofuel production.
Nebraska currently ranks 1st in irrigated acres, 1st in commercial red meat production and is tied with Texas for cattle on feed, 2nd in corn-based ethanol production, 3rd in corn for grain production, 4th in soybean productions, 6th in all hogs and pigs, and 7th in commercial hog slaughter, and 9th in table egg layers. However, in reading this white paper, one quickly realizes we’re not taking advantage of the tremendous grain production capacity here in the State.
We export over 1/3 of our annual corn crop, at least half of the in-state production of distiller’s grains (a co-product from ethanol production that is fed to livestock), and more than 80% of our soybean meal output. Corn and soybean production have increased in our State by 50 and 25% respectively, which is a blessing due to our irrigation capacity. But increasing amounts of this grain are being shipped out-state instead of benefiting rural economies in Nebraska if it was used in-state for value-added livestock production and processing instead.
In the white paper, graphs are shown comparing Nebraska to neighboring states. These graphs show Nebraska lagging neighboring states in growth of the livestock industry. For example, while Nebraska overall increased in hog production, the inventory increased 17.2% during the first half of the decade, but declined 11.8% in the second half. In comparison, Iowa realized an increase of 31.5% within the decade. What was really interesting to me is the fact that Nebraska exports 2.5 million pigs annually to neighboring states to be finished and shipped back to Nebraska for processing, showing potential for growth in the market hog sector. The dairy sector has also declined in herd numbers in Nebraska compared to other states and Nebraska’s poultry industry (mostly egg laying hens) has declined over the past decade in spite of constant numbers across the U.S.
When one looks at Nebraska’s economy, cash receipts from all farm commodities totaled over $25.6 billion in 2012 and livestock/livestock product sales was 45% of this total ($11.6 billion). Increased employment, local tax revenue, value-added activity, and manure for fertilizer are all economic benefits of livestock expansion. The paper stated,
A base expansion scenario that includes a 25% increase in market hogs, a doubling of dairy cow numbers, a ten percent increase in fed cattle production and a tripling of egg production, along with the associated processing industries, has the potential to provide an additional 19,040 jobs, with labor income of almost $800 million and value-added activity of over $1.4 billion. This activity has the potential to generate over $38 million in local tax revenue. While this amounts to a fairly small percentage of Nebraska’s total economy, these impacts will occur almost entirely in non-metropolitan areas of the state and would be quite beneficial to rural economies.
Livestock development has been held back by various issues and policies including: limitations on corporate farming activity in Nebraska, state and local permitting processes, nuisance roles and lawsuits, and issues/concerns from the general public and interest groups. The final conclusion of the paper was that significant growth in employment and economic output throughout Nebraska is dependent upon these issues being overcome.
I would challenge all of us to keep an open mind when producers desire to diversify by including livestock in their operations or through livestock expansion. In many cases, doing so allows another person to come back to an operation, or allows someone to get started farming, which in the long run benefits our rural economies. It’s ok to ask questions, to become more educated. It’s through these questions that one learns how production practices have changed to ensure the health and welfare of our livestock and in odor reduction from the facility and manure application.

Nebraska On-Farm Research Updates

Another one of my favorite winter meetings, and honestly, one of the most powerful farmer learning experiences I have the opportunity to take part in, is the Nebraska On-Farm Research Network and the winter Updates! Why is this such a powerful experience? Because the farmers who conduct the research are the ones presenting what they did, why they did it, and their results! The discussion amongst farmers, ag industry, and Extension is highly engaging and thought provoking. Great questions are asked. But even more powerful is the understanding that occurs on what valid research is and how to question what one sees and hears presented at meetings, in magazines, and online. The Nebraska On-Farm Research Network is sponsored by the Nebraska Corn Board and Nebraska Soybean Board via your checkoff dollars and this year we are having meetings at three locations in the State. February 13th will be at College Park in Grand Island; February 16th at the Lifelong Learning Center in Norfolk; February 17th at the ARDC near Mead and all meetings will begin at 9:00 a.m. and last till 3:00 p.m. There is no charge for these meetings but pre-registration is needed for meal count and ensuring we have enough materials and space. Please pre-register for all meeting locations by calling (402) 624-8000 or email christina.franklin@unl.edu. There are five CCA credits pending approval. Hope to see you at one or more of the meetings!
Ag Reflections from 2014
Happy New Year! Wishing all of you and your families a wonderful 2015! As I look back at 2014, there are several ag-related observations that I noted throughout the year.
The first observation continues to be the way communities and people in this County/area pull together in difficult times. Whether after tornadoes/wind storms or helping other farm families who had an injured family member or had lost a family member, it’s just a blessing to see the way people pull together to help each other in time of need. It was also a blessing for many who were unable to harvest in 2013 due to the August 1st storm, to harvest fields in 2014, and for many in the area to experience really good irrigated and dryland yields this year.
The dry winter of 2013/14 allowed for very mellow ground during planting time. Often seeding depth ended up ½-1” deeper than intended. The dry winter also didn’t allow for good residue decomposition leading to problems during planting and ensuing stand emergence. Cutting off residue and high rains in May led to unintended consequences of replant situations when residue was moved off of farmers’ fields onto neighboring fields, suffocating emerged plants in portions of fields. I’m not sure what the solution is for the future other than it really needs to be something worked out with neighboring farmers, but perhaps mentioning it here opens an opportunity for future conversations.
Cover crops have been incorporated into more operations in recent years, yet the ultimate goal for using them remains important in determining what species/crops are used in the fields. We also realized the importance of determining amount grazed prior to turning cattle into fields (whether for grazing cover crops or crop residue), as high winds in winter 2013/14 in overgrazed fields led to soil blowing throughout the winter.
The May frost showed us emerged soybeans at the cotyledon stage held up well to the frost compared to the corn. We also again watched Goss’ wilt show up systemically by 6 leaf corn that was injured early by frost or hail in fields where Goss’ wilt had been a problem in the past. We need more research/understanding of this disease. Wheat continues to show us its resiliency as it winterkilled in portions of fields, withstood drought-stress, and then made up yield in the last 4-6 weeks.
Perfect pollination conditions coupled with high solar radiation, low night-time temperatures, and timely rain events were keys to the bountiful corn crop we experienced this year. Soybeans were more of a mixed bag. In walking fields and in conversations with farmers, I think the disappointment in some irrigated yields could be attributed to early/over-irrigation, disease problems, and planting date. UNL on-farm research showed on average a 3 bu/ac yield increase when soybeans were planted in late April to first week of May (regardless if growing season was warm/dry or cold/wet like it was this year) and those I’ve talked to who achieved 80+ bu/ac in the area this year planted in that time-frame. I’m curious if there’s something to planting a 2.4-2.5 maturity early vs. a 3.0+ maturity early as some area producers are seeing strong yields from a shorter season hybrid planted early the past few years. So if you’ve also seen this and/or are interested, that will be an on-farm research project to try next year. Please let me know if you’re interested!
Here’s wishing you a healthy and prosperous 2015!
Soybean Stem Borer

Are you noticing holes in your soybean stems? Holes where the petiole meets the main stem are the entry point where soybean stem borer (also known as Dectes stem borer) larvae tunnel into the main soybean stem. Originally eggs are laid in soybean leaf petioles in the upper canopy. The eggs hatch into larvae which burrow down the petiole then into the main soybean stem. Notice the soybean stem borer infected stem in the middle while the soybean stem to the right has a a non-infested area where the petiole dropped (it is naturally sealed over by the plant). Count how many plants out of 20 have this symptom to get an idea of percent infestation and repeat in several areas of the field. Fields with 50% or more infestation need to be harvested first and perhaps earlier to avoid lodging and yield loss associated with lodging.

Lodged soybeans can be another key for checking for stem borer around harvest time. Notice the stem in the middle of the photo that is lodged (fallen over instead of standing in the row).

Following the stem to the base, the stem easily breaks away from the plant. The stem itself will appear solid. The base of the plant where it breaks is also often sealed off. The stem borer will seal itself inside the base of the stem. In this case, there’s a small portion that hasn’t been sealed off yet.

Gently pulling apart the base of the stem reveals the soybean stem borer larva. The larva will spend the winter and eventually pupate here. Adult beetles will emerge in late June and there’s only one generation per year. For more information specific to life cycle and management, please see the following NebGuide.
Crop Update 8/1/14

Southern rust of corn confirmed in Clay County July 31. Very small, tan-brown lesions on upper surface of the leaf, usually in clusters. Spores inside the pustules are typically orange. This was found on one leaf in a field near Trumbull. Just because southern rust has been found in the area, we don’t recommend automatically spraying. Scout your fields and consider disease pressure, growth stage, and economics. Long season corn and late-planted fields have the potential for most damage. Secondary common rust sporulation has also been confused as southern rust as the secondary pustules tend to look like this. It’s important to obtain microscopic confirmation to know for sure if you have southern rust in your fields.

Microscopic Observation: Spores of southern rust appear elongated vs. common rust appear as near perfect circles.

Another common problem is old common rust lesions being confused as gray leaf spot. The color of this lesion is a tan-gray, typical of gray leaf spot. Using backlighting or a handlens, you can see the pustules within this lesion confirming it is common rust and not gray leaf spot. I’ve had many calls that gray leaf spot was up the entire plant in their fields and after looking at fields, have found it to be common rust in most situations. It’s important to know what disease you truly have to make the best decision on fungicide application.

Have also received questions on soybeans, particularly in dryland. This photo is showing drought stressed soybeans-often occurring in pockets within dryland fields right now. Closer observation shows plants aborting pods and losing lowest leaves. Spidermites can also be viewed on leaves in some of these patches.
Storm Damage Resources

Field flooding occurred in newly planted and newly emerged fields throughout the area after recent rains.

Large trees were uprooted falling on buildings, homes, and cars in Sutton after the May 11, 2014 tornadoes.
The Mother’s Day 2014 storms caused significant damage in Clay County and other areas of the State. It never ceases to amaze me how people throughout the area respond to storm damage! Clay County has had its share, and yet the attitude of those affected has been one of thankfulness-thankfulness that no one was injured and that so many still have their homes in spite of damage. It’s also wonderful to see people from all over the County and area pull together with each storm-helping each other out bringing themselves and equipment to pick up debris or help however possible. It’s a blessing to work with and serve the people of this County!
