Soil Crusting in #Soybeans Causing Concerns
On May 6, quite a storm was unleashed in south central Nebraska. Soybeans that had been planted two to three days before the
storm seem to have emerged fine, while those planted May 5-6 tend to have uneven emergence and crusting. This is occurring regardless of tillage type, residue cover, etc. Many farmers have been running pivots to help the soybeans break through the ½- to 2-inch crust, often applying an inch of water before they see stand improvements.
The primary question for growers has been “Should I replant?”
UNL on-farm research has shown less than 1.4-2.0 bu/ac yield difference between planting 90,000 and 180,000 seeds/acre. (See report.) In our research, 90% of the planted stand was achieved at both seeding rates in irrigated 30-inch rows in no-till and ridge-till fields.
Consider what was found in 2006 in one dryland field in Nuckolls County where populations of 100,000, 130,000, and 160,000 seeds/acre were planted. This field was at the cotyledon stage when it was hailed. Some plant stands dropped to 67,000. Yield was 4 bu/ac less than in the 160,000 seed/acre planting that had a final stand of nearly 98,000. The average yield in the field was 40 bu/ac. While this is only one field and one year of research, it is an example of how soybean plants can compensate for reduced populations by branching and how August rains in dryland can still allow reasonable yields to be produced.
UNL research conducted by Dr. Jim Specht, UNL Soybean Physiologist, also has shown that for every day planting is delayed after May 1, there is the potential to lose 1/4 to 5/8 bushel per day. As we near the end of May and early June and consider that late planting yield penalty and the dry soil conditions (particularly in dryland fields), along with the seeding rate results from this UNL on-farm research, we are recommending that growers leave stands in many fields. Based on our on-farm research, leaving dryland stands of at least 65,000 plants/acre and irrigated stands of 90,000 plants/acre is likely a better choice than replanting.
We realize that there are some larger gaps in various rows in the field, and while we don’t like to see that, the gaps are disappearing as plants continue to grow and branch out. Keep in mind that a gap in one plant row will be compensated by plants in the adjacent flanking rows. They will form extra branches to take advantage of the sunlight, thus single-row gaps may not be as yield-reducing as you might think — especially in 15-inch row spacings.
We’re also seeing how resilient soybeans are. Some soybeans have been in the ground for two weeks and in many cases, are fairly healthy below the crust. Soybean seedlings emerge by pulling (not pushing) their cotyledons upward. The seedlings rely on the cotyledons as a reserve source of carbohydrate, protein, and lipid to support early seedling development until leaflets open for photosynthesis. When a seedling tries to pull its cotyledons through a crack in the crust, the crack may be too small and the cotyledons may be stripped off.
The plumule, which is the seedling stem tip and its undeveloped leaves above the cotyledonary node, may remain, but 
without the cotyledons to serve as a carbon and nitrogen source, development of new seedlings with small leaflets will be slow. These plants may not become competitive with surrounding plants in terms of pod and seed production. Therefore, when counting seedlings to determine plant stand after a soil crusting event, count only the seedlings that have at least one cotyledon. You can count seedlings missing cotyledons if they have large unifoliolate leaves that will soon unroll such as the picture on this page.
Recommendation: When deciding whether to replant your field, consider UNL research findings that showed a minimal yield difference between stands of 90,000 and 180,000 seeds/acre. We recommend leaving irrigated soybean plant stands of 90,000 or more and dryland plant stands of 65,000 or more. Uniformity of plant stands is also important, but “patch” planting may be used to deal with local areas of low plant stands.

Future of Rural America
Sunsets over rolling hills of green pastures and straight corn rows. Barely seeing above soybeans I was walking to remove 
weeds. Attending a small school that provided an excellent education with opportunities to participate in a variety of activities to become more well-rounded. These are a few of numerous memories of growing up on the farm and in a rural community that I hold dear. While I enjoy hearing my grandparent’s stories of what life was like for them farming 60 years ago and even enjoy watching the Nebraska State Cornhusking Contests held each year, I also realize times have changed and don’t have a false sense of nostalgia about what rural means today. While technological advances allow our farmers to produce more food for more people with less inputs and less water than ever before, what hasn’t changed about rural communities is the hard work ethic, dedication, risk, determination, and reliance on Faith and family to get through each year.
Last week I had the opportunity to participate in the Rural Futures Conference held in Lincoln. For me, it was the best conference I’ve attended; the energy and enthusiasm from 450 people gathering from a variety of backgrounds all to discuss the future of rural America was refreshing to say the least. My favorite part of the conference was the first evening. The key note speaker Joel Sartore, a Nebraska native who is also a National Geographic photographer, challenged us to maintain a positive attitude and to look for the opportunities that were available in our small towns. For example, one town in Kansas was all about a certain sparrow where they would take people out on field trips to “listen”-they didn’t even get to “see” the sparrow-and people paid money for that! There was also a town in Oklahoma where all they had was rattlesnakes…so they made the most of that too and created a huge attraction around snake handling, pics with snakes, snake skinning, etc.
My favorite part of the conference occurred after that during the youth panel. A panel discussion with Caleb Pollard, 
Executive Director of Valley Co. Economic Development in Ord, NE; Amanda Crook, Graduate Student; Anne Trumble, Executive Director of Emerging Terrain in Omaha; Jim McClurg, University of Nebraska Board of Regents; and University of Nebraska Med Center’s Bob Bartee answered questions moderated by Dr. Ronnie Green, IANR Vice Chancellor. The young people struck a chord with me-most likely cause we were of similar age. Some key take-away quotes:
- Vibrant organizations identify strong leadership.
- Failure can be a good thing as it can lead to the next innovation.
- To go some place and change the trajectory of history is exciting!
- We need to change the way we place young people into jobs….we don’t offer young people jobs; we offer them opportunities.
These young people were so excited about living in Nebraska! Some of them had spent time elsewhere before choosing to move back to Nebraska and eventually choosing to find a small town to raise their families or have the rural way of life. Another theme that emerged throughout the conference was the need to get young people involved in the local community such as youth representatives on city council, etc. even as early as when they’re in high school. Some people think small town communities in Nebraska are dead…but that’s not necessarily the case. It mostly depends on leadership-a strong leader will rally the town around an idea to grow it or create opportunities. That’s what’s happening in Ord, NE with Caleb Pollard. Another example comes from Fairfield Iowa. Sometimes it just takes the right person to ignite a spark and help the rest of the town see the possibilities. Nebraska has so much to offer!
Frans Johansson, author of The Medici Effect, was also a phenomenal speaker! He spoke about creating breakthrough innovations by thinking outside the box and working at intersections of different disciplines/cultures, etc. Key points I obtained from him include:
- New ideas are combinations of existing ideas.
- People who change the world try FAR more ideas.
- Diverse teams can unleash an explosion of new ideas.
- Find inspiration from fields/cultures other than our own.
- Look for the smallest executable step-essentially don’t eat the elephant in one bite.
- Stepping into intersections isn’t risky-it’s risky to do the same thing over and over again.
Maybe these aren’t earth-shattering new concepts, but good reminders for a task as large as creating a Rural Futures Institute…and frankly for anything in life.
There was much discussion about the role of a University/State/Community Colleges in trying to save rural communities…how is this done…how build partnerships and trust…how to provide incentives to faculty working in creative/innovative ways in a structured academic setting when it comes to promotion and tenure…and even if the University changed its incentives, how does that bode if a faculty member moved on to another University? How are incentives provided to teams and excellent team work? We are standing at the crossroads…maybe an intersection right now in academia which can shape the future of creatively rewarding innovative work while still maintaining needed structure in the promotion/tenure process. I remain positive that we’ll find a way to work through this!
There were discussions in small groups regarding the meaning of rural. What does it entail? Often we think of agriculture-and I would argue that’s a strong part of rural-but it’s also much more…health care, infrastructure, industry, schools, broadband, etc. Some were saying we need to use the term non-metro instead of rural in order to get away from the ag connotation. Yet others felt the discussion was too focused away from agriculture on other components of rural and missing ag as a key component. Needless to say, the entire conference provided interesting discussion, dialogue, and a chance to meet people from a variety of backgrounds. It truly provided an opportunity to look for intersections with which to create innovative ideas for the future.
There was also the reality that hit during focused group conversations that there are also problems that need to be addressed in rural communities that weren’t touched on at this point: poverty; crime; infrastructure; food deserts; building trust and interfacing with university, college, and other partners, etc. Overall it was a thought-provoking conference and has the feel that several small steps can be achieved in the coming year. I would encourage you to check out the Web page and follow the Facebook page. You can also check out the Twitter Conversation at #RFC2012. This conference was also not just focused on Nebraska as the focus was the Great Plains and people from numerous states attended. I’m looking forward to seeing the small executable steps that will occur in the future and am also looking forward to doing my part to maintain strong rural communities as I’d like to see the next generation enjoy the rural life and learn the values I did growing up!
The Season for #ag & #horticulture Questions!
This past week was a blur of calls, questions, and visits to homes and fields but it was a great week and flew by staying very busy! I’ll touch on a few of the common questions I’ve received this week.
Trees: Some trees such as willows, hackberries, tops of maple trees, ash, and black walnut are just taking time leafing out. Some trees leafed out once already and dropped leaves. Things that may have caused this were the sudden flux of temperatures from very warm to cool and the strong winds we received. Some trees have also unfortunately had herbicide drift damage that caused leaves to drop. On those trees, watch for new buds as nearly every situation I’ve looked at thus far have new buds forming after about a week-10 days. With all these situations, give the trees a few weeks to leaf out again and if they’re still not doing it, feel free to give me a call. Trees are interesting plants as sometimes environmental impacts that happened 3-5 years ago will show up that much later-and sometimes environmental impacts show up right away!
Disease/Insect issues: This year has been a strange year all around but with our warm winter, I was concerned about an increase in diseases and insects. Thus far, we’re experiencing increases in both-so hang on-it may be a long growing season! Our high humidity, warm temps, and heavy dews have created perfect conditions for fungal diseases on our trees, ornamental plants, lawns (I’m currently fighting a bad case of powdery mildew-as a plant pathologist it is kind of pretty but I don’t like what it’s doing to my lawn!), and in our wheat and alfalfa crops and some pasture grasses. Fungicides may help in some of these situations, increasing airflow can also help as can more resistant varieties or hoping the weather will change. In the case of most ornamentals, we don’t usually recommend doing anything. The same goes for insects as insecticides can help in some situations. I’ve received several calls this past week of people afraid they had herbicide drift damage. While there were a few cases of that, many of the cases were actually fungal leaf spots on leaves. There are various fungicides and insecticide products available from home/garden centers, etc. Be sure to read and follow all label directions and only apply the product on places the label specifies it can be applied.
Crops Update: Later this week we may have a better idea on the extent of storm damage and if some fields will need to be 
replanted after the storms from last week. Dr. Bob Nielsen from Purdue University reported that most agronomists believe young corn can survive up to about four days of ponding if temperatures are relatively cool (mid-60’s F or cooler); fewer days if temperatures are warm (mid-70’s F or warmer). Soil oxygen is depleted within about 48 hours of saturation and we know soil oxygen is important for the root system and all the plant’s life functions. So we’ll have to wait and see what happens.
Have also had a few calls regarding rye cover crops. When rye is killed out and decomposing, it releases toxins that can affect the germination of other cereal crops such as corn if it’s going to be planted into that rye cover crop. Thus we recommend at UNL that the producer kill the rye and then wait at least two weeks to prevent any major damage to the crop. I realize at this point with the rains to get in and kill that crop on top of waiting an additional two weeks, we’re getting close to the end of the month and will most likely be looking at reduced yields…and depending on maturity, you may need to consider different seed if you end up having to plant in June. If you have specific questions about this, please let me know and we can talk through some situations.
Stripe rust and powdery mildew have been obliterating mid-lower canopies of many wheat fields. I’ve received several calls
on why wheat canopies are yellow-that’s the main reason but other factors such as the dry spell prior to these rains and/or deficiencies in nitrogen/sulfur or some viruses may also have been factors. Wheat in Nuckolls County last week was beginning to flower. Fungicides such as Prosaro, Folicur, or Proline are labeled for up to 50% flowering and cannot be applied after that. Remember the wheat head begins pollination in the middle-so if you’re seeing little yellow anthers at the top or bottom of that head, you’re towards the end of flowering. All those products have a 30 day pre-harvest interval-which has been the other main question-are we going to be harvesting in a month? I do believe we’ll be harvesting a month earlier than normal just because pretty much everything in wheat development is about a month ahead of schedule. I still feel the 30 day window for the fungicide application is worth it with the large amount of disease pressure we’ve seen. Wheat in Clay Co. and north still may have time for a fungicide application; those products mentioned above will help prevent Fusarium Head Blight (scab) as well as kill the fungi causing disease already present on your leaves. A list of all fungicide products, pre-harvest restrictions, and rates can be found here. Also check out my previous blog post with video on scouting for wheat diseases.
The other major disease appearing in wheat is barley yellow dwarf virus. This is a virus vectored by bird cherry oat aphids which we were seeing earlier this year. Unfortunately, this disease causes the flag leaves to turn bright yellow-purple causing yield loss (at least 80% of the yield comes from the flag leaf) as there’s nothing you can do once the virus manifests itself in those leaves. If you have a large incidence of barley yellow dwarf in your fields, you may wish to reconsider spraying a fungicide as the fungicide won’t kill the virus; however, it will help kill the fungi on the remainder of your leaves and potentially help protect some yield from the two leaves below the flag leaf.
Evergreen Tree Diseases
Somehow April flew by without me reminding you to apply fungicide sprays to Austrian and Ponderosa pines that have had 
problems with Sphaeropsis tip blight in the past. I’ve also received several scotch pine samples in the office to diagnose for pine wilt nematode. While there is no cure for pine wilt, I recommend to take a 6” long, 1-2” diameter sample of a dead branch to your local Extension office for diagnosis before cutting down the tree. Pine wilt affects Austrian (long needles groups of 2) and Scotch pines (short needles in groups of 2) as they are non-native trees while the nematode is native. Since ponderosa pines (long needles in groups of 2 and 3) are native to Nebraska, they don’t seem to be affected by pine wilt nematode.
Pine wilt is caused by beetles carrying pine wood nematodes vomiting them into the water-carrying vessels of the tree (xylem). The tree senses the nematodes and essentially blocks water to those branches. Often you will observe a branch then perhaps a side of the tree and eventually complete death of the tree within 6-9 months. While I have diagnosed many samples of pine wilt, more often when I visit homeowners the tree problems are due to fungal diseases which occur on the needles. If you look closely at your needles and observe dark bands or rings on them followed by death of the needle either direction from the band, the tree problem is most likely due to a fungal needle blight like dothistroma in Austrian and Ponderosa pines or brown spot in Scotch pines. They can all be prevented by spraying a fungicide containing copper sulfate in the spring.
With everything about 3 weeks early this year, now is the time to spray Ponderosa and Austrian pines for needle blight and spruce trees that have had problems with needle cast or shoot blight where the new growth has died in the past. In early June spray for needle blight problems in Scotch pine and cercospora blight on cedars. If you have a windbreak of combinations of these trees and don’t want to spray twice, I recommend at least spraying in early June to catch all of them. Increasing air flow by cutting out some trees is another way to reduce fungal diseases on your trees.
Also watch trees for bagworms as you may be able to tank mix a fungicide/insecticide application in early June if needed. We would recommend picking the bags off trees and burning them, but that’s just not feasible in windbreak situations. To know when to spray, take a few of the bags off the tree, place them into a plastic ziplock bag, and place outside on the south side of your house. When the larvae emerge from the bags, check your trees to see if larvae can also be observed on them. Pyrethroid insecticides are recommended for managing bagworms because they cause an irritation that makes the larvae leave the bags and allow them to be exposed to the pesticide.

Drop #Soybean Seeding Rate & Save $
Increasing input costs are forcing producers to evaluate every decision they make. With soybean seed costs on the rise, producers in the Greater Quad County On-Farm Research group wondered if they could reduce their soybean populations while maintaining yield and saving money. On-farm research conducted in field scale, randomized, and replicated farmer plots and at the South Central Agricultural Laboratory near Clay Center from 2006-2008 proved producers could.
Since 2006, planting rates of 90,000, 120,000, 150,000, and 180,000 seeds per acre have been planted in 12 irrigated soybean fields on 30-inch rows. Prior to this research, most of these producers usually planted 160,000-180,000 seeds/acre. The 90,000 low rate was determined based on UNL research recommending not to replant a hailed soybean stand if at least 90,000 plants/acre remained in the field.
|
|||||||||||||||||||
In 2008, cooperating producers used these same rates to plant soybeans at five sites with 20 replications. Planting dates ranged from April 29 to June 3. In the end, there was little difference in percentage stand and yield among the four planting rates (see Table 1). The 120,000, 150,000, and 180,000 yields were statistically the same (only a 0.3-bushel difference between the 120,000 and 150,000 rates) and were significantly better than the 90,000 seed-per-acre plots; however, note that the 90,000 plot yielded only 1.7 bu/ac less than 150,000 plot. All data was statistically analyzed to determine the yield differences due to the various treatments.
The findings are similar to the 2006 and 2007 studies. In 2006, yield results ranged from 65.5 bu/ac at 90,000 to 67.4 bu/ac at 180,000. In 2007 yield results were 59.4, 59.6, 59.4, and 60.2 bu/ac for 90,000, 120,000, 150,000, and 150,000 respectively with no statistical difference.
Most likely, these results are indicative of soybean’s ability to compensate for reduced populations. Figure 1 shows increased plant branching at lower populations compared to less branching at higher populations. This was observed in all fields regardless of variety. Also observed in 2008, were two additional nodes/plant at the 90,000 population compared to the 180,000 population. Nodes are important as flowers, pods, and ultimately yield are produced from them.
A dryland field in Nuckolls County also showed interesting results. This field was hailed at the cotyledon stage, so planted populations of 100K, 130K, and 160K became average actual stands of 74,417; 89,417; and 97,917 plants per acre. August rains in 2006 helped deliver yields of 38.6, 40.6 and 42.7 bu/ac, respectively.
Figure 1a. Lower planted populations of 120,000 compensated for reduced plants by increased branching, flowering, and pod set, regardless of typical variety architecture.

Figure 1b. Fields with planted populations of 150,000 were observed having a more erect architecture with reduced branching compared to fields planted at rates of 120,000. |
Rates for Drilled Soybean:
In 2006, one drilled field in irrigated conditions in Fillmore County yielded 68.4 bu/ac, 66.6 bu/ac, and 67.2 bu/ac for planting rates of 150,000, 175,000, and 190,000 seeds per acre respectively. Another study in 2006 conducted by the Soybean Feed Grains and Profitability Project in a rain-fed field in Lancaster County showed a slight but significant yield advantage to drilling soybean at a rate of 152,500 seeds per acre compared to 115,000 seeds per acre. Yield for the higher seeding rate was 56.8 bu/ac compared to 56.0 bu/ac with the lower seeding rate. When using grain drills and reducing soybean populations, variable seed spacing and seed depth within a drilled row can be an issue for soybean emergence. This is why a population increase for drilled beans is often recommended.
Recommendation: Plant Soybeans at 120,000 Seeds/Acre
Based on three years of consistent research results, UNL specialists recommend reducing planting populations from an average of 160,000 seeds/acre to 120,000 seeds/acre in 30-inch rows. This reduction of 40,000 seeds per acre results in a savings of $10.66 to $18.57 per acre based on seed costs of $40-65 a bag. For three years producers were able to achieve a 90% stand and have not seen a statistical yield variance from 150,000 or even 180,000 seeds/acre. With soybean seed costs increasing, reducing soybean planting populations is another way producers can survive high input costs of crop production.
Plant #Soybeans Early for Increased Yields
While I got this posted in our CropWatch Web site, I didn’t get it on my blog till now! Hopefully this inspires many of you to get soybeans planted yet this week! 
Planters are rolling throughout the state and given the size of today’s equipment corn planting is rapidly progressing. Based on UNL research, we would encourage you to consider planting your soybeans as soon as possible—preferably before the end of April for the southern two-thirds of Nebraska and or the first week of May for the northern third of Nebraska. While evening temperatures have been low, consider the percent risk of frost for emerged plants not planted seeds. The above recommendation considers a 10% risk of frost 7-10 days after planting, the time when soybeans would most likely emerge.
Why plant early? Five years of UNL small plot and on-farm research has proven that early planted soybeans yield more than late planted beans—regardless of whether the spring has been cold and wet or warm and dry. Soybeans are a photoperiod-sensitive crop so the goal is to allow the plant to use the sun’s energy to accumulate as many nodes as possible as day length decreases after June 21. Nodes are important because that’s where pods, seeds, and ultimately yield are produced. The goal is to have the soybean canopy “green to the eye by the fourth of July!”. Thus the plants are absorbing all the sunlight possible not allowing any to be wasted by hitting the soil.
Table 1 shows how three years of on-farm research have resulted in an average of 3 bu/ac yield increase (with a range of 1-10 bu/ac depending on the year and the planting date range of early versus later planting). With today’s soybean prices, a 3 bu/ac yield increase adds up (see Table 2). We do recommend a fungicide/insecticide seed treatment to reduce the risk of damping off diseases and bean leaf beetles which tend to feed on early-planted soybeans.
Several previous CropWatch articles explain soybean planting date in more detail. Please see these for more information:

Lawn Care
I really appreciated Gary Zoubek presenting at our lawn care workshop last Thursday! I also appreciated all the questions and
good discussion; hopefully everyone walked away learning at least one new idea or tip!
One common question was what to do with areas that were killed out by summer patch last summer. Summer patch is a fungal disease that is favored by applying nitrogen too early in the spring, by a compromised root system by too wet of soils in the spring, by stress from summer heat, and irrigating in the evenings. Last year I was receiving calls from all over the County regarding this disease. Eventually affected areas can refill, but in many cases, that just didn’t happen. Preventive fungicides right now are recommended to help prevent the fungus from causing damage to your lawn again this summer. 
So besides a preventive fungicide what can you do? The best time to reseed is actually in the fall. One option is to keep these areas weed-free including of crabgrass so that doesn’t overtake these areas. Reseed with a disease resistant variety in the fall following the recommendations in this extension circular.
Your other option is to reseed/overseed right now with a disease resistant variety knowing that you may fight crabgrass this first year. Overseeding and reseeding are recommended to occur from now through May 1 for Kentucky bluegrass and from now to early June for tall fescue. You can determine the correct timing of all lawn practices by visiting the turf calendar Web site. Simply choose whether you have Kentucky bluegrass or fescue. Click on a lawn practice and scroll the circle on the calendar area to the current month to find the recommendation for that time.
Some other tips regarding lawn care: sharpening lawn mower blades is key to not shredding the grass which can invite pathogens that cause disease; mulch lawn clippings as often as possible as they contain nitrogen that can be released back into the soil; use a fertilizer product with the highest amount of a slow release nitrogen as possible (check fine print on the fertilizer bag); and sweep or use a leaf blower to send all clippings and granular pesticides back onto the lawn as leaving them on the sidewalk allows for them to be washed into the gutters and eventually lakes and streams. Right now, a silvery colored fungus called powdery mildew is visible in places in lawns that are shady or have minimal air movement. We don’t typically recommend a fungicide as this disease is more aesthetic than harmful.
Here’s wishing you a nice lawn this summer! Also a reminder of our free Container Gardening workshop to be held April 19th from 5:30-7:00 p.m. at the Clay County Fairgrounds. Elizabeth Killinger, UNL Extension Educator, will be presenting on container gardening for vegetables and flowers, creating a few container gardens for door prizes, and provide creative ideas for container gardening. Please RSVP at 402-762-3644 so we can have a meal count, hope to see you there, and invite your friends!
Spring!
Happy Belated Spring! I meant to get this posted earlier this week but just didn’t get it done. I love living in Nebraska and 
being able to observe God’s creation via the changes in seasons! Spring and Fall are probably my favorite, but there’s beauty in all of them. Everything is 2-3 weeks early this year so will be interesting to see if we end up with March going out like a lion or if we end up with an Easter freeze like we did a few years ago. While it wasn’t a bad winter, I always enjoy seeing new life and green in the springtime!
Grass greening up in front lawn. Sending this pic out to my husband who has seen grass very little in 9.5 months in Afghanistan! Will look forward to you helping me mow when you return! : )
My favorite tree is the magnolia and someday I hope to have one! I always enjoy going to UNL East Campus in the spring and seeing the magnolias in bloom. However, I was surprised how quickly they bloomed this year and that they were already loosing their blossoms!
Through the leaf mulch even my iris and daylillies are emerging. I haven’t removed mulch yet in the event we end up with a cold snap. It’s still early, though tempting!
Great resources from UNL regarding horticulture and turf: http://byf.unl.edu/ and http://turf.unl.edu/.
Women in #ag #farm Transition
Last week I attended the Women in Ag Conference in Kearney. It’s always a great conference to see many friends and meet 
new ones who live and work in agriculture! I also enjoyed teaching a very engaged group of women the second day about crop science investigation. It was fun for me to see them dig into the hands-on activities!
The first session I attended was by Dave Specht from the UNL Ag Economics Dept. He does a great job of relating to the audience and talked about “Woman’s Influence-the Key to Generational Business Transitions”. Dave has a consulting business on the side and as part of that business he meets with families to develop a farm transitional plan based on the Continuity Quotient he developed. The Quotient contains 7 parts and I’ll share some key highlights via questions he raised that stuck out to me. Perhaps they’ll raise more questions for you as well.
1-Business/Estate Planning: The goal of the business/estate plan is to reduce the number of surprises to the farm and family members upon death of the farm owner. Is your plan coordinated with all the advisers in the operation and does it consider the perspectives of all the generations involved in the operation? Is it even documented and has it been communicated to the entire family before the owner passes away?
2-Communication: Are family members able to openly discuss the farm and what it means to them?
3-Leadership Development: No one is ever “ready to take ownership”; it is learned along the way. Opportunities for the next generation to make decisions need to be allowed. Often we hear of exit plans, but is there an “entrance plan”-a strategy to invite the next generation back to the farm?
4-I didn’t catch the name of this point but essentially Dave was saying that if the next generation is always asking his/her parents for a bailout, that it delays the trust that the person can someday operate the farm. How the next generation handles personal finances is important in showing he/she can someday run the operation.
5-Personal Resilience: How does the next generation handle challenges? Does the person retreat and avoid them or does the person look for ways to overcome them and use it as a growing experience? If the person retreats, he/she may not be wired for ownership in the future.
6-Retirement/Investment Planning: When will the older generation plan to retire? How much will the farm support (meaning how many people)? Where will retirement cash flow come from? The goal is to not rely on the next generation to generate your entire retirement income.
7-Key non-family employees: Sometimes the most valuable family business asset goes by a different name! Is the vision for the family farm communicated to these employees? How you talk about employees to next generation and how you talk to next generation about the employees is important in dictating future partnerships; someday the employees and next generation will be partners.
I would recommend checking out Dave’s Web site at http://www.davespecht.com for more information. He provides communication and consultation about farm transition and financial planning. Life is so short! Make sure you have a plan in place that follows the keys Dave provided above!
