Army cutworms have been found in some wheat and alfalfa fields. I honestly haven’t looked at pastures but have gotten several calls about pastures this week, so perhaps be looking at them as well. The threshold is four or more cutworm larvae per square foot of winter wheat or alfalfa. A lower threshold is necessary for stands that are new or had some winterkill/drought-stressed. Damage looks like chewing on the leaves stems to complete stand reduction. Army cutworm larvae are greenish-brown to greenish-grey caterpillars, approximately ½ to two inches in length. They feed at night so you may have to look under residue or dirt clods to see them in the day.

Nitrogen Fertilizer Trends in Nebraska from 1955-2023: Dr.’s Richard Ferguson, Bijesh Maharjan, and Javed Iqbal wrote a nice updated article on nitrogen fertilizer trends for CropWatch this week. I pulled out a few excepts here, but please also check out the full article with the graphs and figures here: https://go.unl.edu/ki69.

“As farmers embark on another growing season in Nebraska, most will be applying some form of nitrogen fertilizer to optimize crop production. …  Initially, ammonium nitrate, mostly sold in bags, and anhydrous ammonia were the dominant fertilizer sources. Nitrogen fertilizer use grew steadily from 1955 into the 1970s as fertilizers became more available and farmers saw the benefit for crop production. During this period, urea and urea ammonium nitrate solutions became more available and their use grew. Anhydrous ammonia dominated fertilizer sales during this period, peaking in 1968 with over 75% of total N sold as anhydrous ammonia.

Use of urea ammonium nitrate (UAN) solution (both 28% and 32% N) began to take off in the 1980s, and today is the most dominant form of nitrogen fertilizer used in Nebraska. In 2022, 57% of all N consumed in Nebraska came from UAN solutions, while 23% came from anhydrous ammonia, and about 14% from urea.

Total nitrogen used in Nebraska began to plateau around 1980 until about 2010. Since then, trends for increasing total N use have been observed. This trend generally coincides with an increase in land area from which corn is harvested. Approximately 8.85 million acres of corn were harvested in Nebraska in 2010, while 9.5 million acres of corn were harvested in 2023.

Figure 4 shows a very positive overall trend, with fertilizer N use of around 1.6 to 1.7 pounds fertilizer N per bushel of corn in 1965, to around 0.8- to 0.9-pound fertilizer N per bushel of corn in 2022. This positive trend illustrates that Nebraska farmers have become much more efficient through the years in managing nitrogen fertilizer.

There are many factors influencing this trend, including genetics advances and overall improvement in production practices. However, it’s likely that a major factor in this trend has been growing awareness of the risk of environmental degradation from excessive nitrogen application, influenced by many educational programs conducted by the University of Nebraska-Lincoln and natural resources districts. This trend is also influenced by requirements in some groundwater management areas for producers to follow nitrogen and irrigation best management practices.

While the general trend for the past 60 years is positive, Figure 4 also shows very little change recently in fertilizer nitrogen use efficiency: it has remained around 0.8- to 0.9-pound fertilizer N/bu since 2000 (circled data points). This data also does not illustrate variations in efficiency that occur in regions across the state. This lack of recent improvement suggests that current widely used practices may have reached their limit in terms of nitrogen use efficiency, and adoption of other tools, such as in-season application and sensor-based fertigation, may be required to further increase nitrogen use efficiency.”

Planting Considerations

Planting Considerations: The warmer air and warming trend of soil temperatures have allowed for planting to begin last week for some. This week hopefully brings some moisture. It also looks like a cooling trend will occur the mid-half of the week with frost potential by the weekend.

Agronomically we’ve come a long way with genetics and seed treatments. Because of this, some don’t worry about soil temps. Yet every year I think most agronomists would say we can trace various problems back to a specific planting date(s) or planting window. So, I still feel they’re an important consideration.

We often hear a preference of planting corn and soybeans in as close to 50F or greater soil temperatures as possible. Below 50F, I prefer to see corn planted on a warming trend of 5-7 days like what we saw last week. The consideration is for soil temps in the mid-40’s on a warming trend with no chance of a cold snap (cold rain/snow) within 8-24 hours for soybean and 48 hours for corn. The time-frame is due to the imbibition (critical water uptake) time-frame for corn and soybean. Soybean seed uptakes water more rapidly than corn and once the imbibition phase is complete, the soybean going through the osmotic phase can tolerate 35-40F soil temps as long as soil is not saturated. Soil temps for your field can be monitored by using a thermometer or checking out CropWatch soil temps at: https://cropwatch.unl.edu/soiltemperature.

Besides soil temperatures, another part of the soil being fit for planting include the soil not being too wet to create sidewall compaction and getting the seed vee closed. I think the greater thing some will deal with is making sure there’s moisture where the seed is placed. I recommend putting corn and soybeans in the ground at 2”. That may seem deep for beans but our UNL research found 1.75” seeding depth provided the highest yield for soybean. It also provides buffered soil moisture and temperature conditions when planting soybeans early. Bob Nielsen, emeritus professor at Purdue said corn can be seeded 2.5-3” deep if that’s where uniform soil moisture is located in order to achieve uniform germination and emergence. We don’t recommend planting soybean deeper than 2.5”.  

For corn seeding rates, it’s best to check with your local seed dealer as all our research shows that optimal corn population varies by hybrid. However for soybean, our recommendation after 17 years of on-farm research studies (2006-2023) in heavier textured soils and 30″ rows continues to be: plant 120,000 seeds/acre, aim for a final plant stand of 100,000 plants/acre and you’ll save money without reducing yields. If that seems too risky, try reducing your rate to 140,000 seeds/acre or try testing it for yourself via on-farm research!

One final thought, make sure you’re keeping yourself and those in your operation safe by wearing proper PPE when handling treated seed, including filling boxes, when seed gets plugged, or when digging up seed. Seed tag labels will list PPE required for the seed treatments in case you weren’t aware of this. Here’s wishing you all the best whenever the planting season begins for your farm!

Alfalfa Weevils and Army Cutworms have been showing up in some alfalfa fields and it would be good to check wheat and other small grain fields for army cutworms. The last time we saw alfalfa weevils this early was back in 2012. Larvae are green with a dark head and white stripe down the back. They can often be found near the soil during the day. Use a sweep net if possible to detect their presence, and if they are present, randomly select at least five sampling sites from across the entire field. At each site, gently pick or cut at least 10 alfalfa stems at ground level. Shake the larvae off the stems by beating the stems into a deep-sided bucket, also looking for any larvae in folded leaflet tips. Count the larvae and determine the average number of larvae per stem. Economic threshold for the mid-vegetative stages of 10-15” tall are 1.5-2 alfalfa weevils/stem (chart can be found at: https://go.unl.edu/pxhk). Highly effective insecticides for alfalfa weevil control include those that are pyrethroids (active ingredient ends in “thrin”, such as Permethrin) and products containing indoxacarb (e.g., Steward). If you spray prior to harvest, check pre-harvest interval (often 7-14 days).

Vegetables and Lawns

Wishing everyone a blessed Easter! While I won’t get to it this year, there are people like me who traditionally plant potatoes on Good Friday. So, that led me to thinking of lawn and garden things. A vegetable planting guide for our area compiled by Emeritus Extension Educator, Gary Zoubek can be found here: https://go.unl.edu/fecq.

Kelly Feehan, Extension horticultural educator shares, “Late March through April is typically the time to plant cool season vegetables. These vegetables germinate and grow in cooler soils and can tolerate light frosts. They include onions, potatoes, radish, lettuce, carrots, beets, peas, broccoli, and cabbage.

A tip for growing large onions that store well is starting from transplants instead of sets. Plants grown from sets may begin blooming in mid-summer. Once this happens, bulbs will not grow larger. Flowering happens because onions are biennials. They grow foliage and a bulb the first season, then bloom and set seed their second season. Growing sets for sale counts as one season and so plants from sets are primed to bloom when growth resumes in our gardens.

When growing onions from seed or transplants, plants are not primed to bloom the year we plant them. Some garden centers and catalogs now sell onion transplants for this reason. If you prefer to start from sets, use dime size or smaller sets as these are less likely to bloom the year of planting.

Potatoes are planted in April, sometimes late March or early May. A tip for increasing potato yields is hilling potatoes after they begin to grow. Once they are 12 to 20 inches tall, carefully scrape soil up around the plant to create a hill.

Potato tubers grow on stolons, underground stems, above the roots. Hilling provides more space for tubers to grow and maintains cooler soil temperatures, especially if hills are mulched. As a cool season crop, cooler soil will increase tuber production.

If potato hills are spaced closer together, tubers grow smaller. If hills are spaced farther apart, tubers grow larger. The recommended spacing is 12 inches between hills and 3 feet between rows. The 12-inch spacing will result in smaller tubers. An 18 to 24 inch spacing will result in larger tubers.”

Soil Temperatures can be found at:  https://cropwatch.unl.edu/soiltemperature. This is helpful for knowing when to plant vegetables, when to plant crops, and what the soil temp is when applying fertilizer to fields. It’s also helpful for homeowners to wait to apply crabgrass preventer for lawns until soil temps are at least 50-55F for 5-7 days straight. In spite of the warmer temps, it’s far too early for crabgrass preventers!

Lawn Seedings: For those who didn’t seed or overseed turf grass last August-September due to the dry conditions, aim to seed or overseed as soon as possible. Weed control can be a challenge with spring seedings, but a new product has helped with this. I tried it last year and it worked well for me. Just know that your weeds will turn white in the lawn. “Scotts Turf Builder Triple Action Built for Seeding” (blue bag) contains fertilizer and the herbicide mesotrione which provides PRE and POST control of weeds without affecting the new bluegrass or fescue seeding.

Male birds: To keep male birds from attacking your windows upon seeing their reflection when they’re establishing territories, consider placing a thin layer of liquid dish soap on the outside of the window. It can easily be washed off in late spring but will protect your windows and the male birds.


I’m writing this on Good Friday. As this song shares, “Friday’s good cause Sunday is coming!”… “Then He breathed His last and bowed His head, the Son of God and man was dead … But that wasn’t the end, let me tell you what happened next … He’s Alive! … now Jesus reigns upon the throne all Heaven sings to Him alone!” Wishing you and your families a Blessed Easter celebrating our risen Savior and our only hope in life and death!

Cover Crop Termination Timing

Cover Crop Termination Timing Tradeoffs: The warmer spring soil and air temperatures until this weekend have allowed small grains like rye, wheat, and triticale to gain quick growth. A small grain cover crop can impact corn and soybean in several ways including: reducing soil erosion, tying up nitrogen, reducing soil moisture prior to planting, increasing insects (beneficial and pests), reducing weed pressure (either via allelopathy towards small weed seeds or choking out weeds), and reducing soil-borne pathogens that cause soybean diseases. Termination timing is often a question. While I’m a fan of planting green, that doesn’t fit each farmers’ goals or situations. The following are things to consider for termination timing.

Termination prior to planting may be of interest to those who are concerned about soil moisture, who are new to cover crops, who have a subsurface drip irrigation system, or are not allowed to plant seed corn green.

One consideration if terminating prior to corn or soybean planting is to consider using clethodim as it doesn’t die as quickly, allowing for longer-lasting erosion and weed control. We’ve been using 10 oz/ac of clethodim. If you do choose to use clethodim vs. glyphosate prior to corn planting, it needs to be applied at least 7 days prior to planting corn. There are no restrictions with soybean.

Termination at or after planting (planting green) is an option for those who want more cover crop biomass for erosion and for weed and disease suppression. When planting soybeans green, the goal is often to off-set the PRE herbicide cost with the cover crop seed and application cost. Reality is, if you’re going to lie awake anxious about this decision, planting green may not be for you. Often, corn plants will not look as good the month of June, but things often turn around come July.

The following are things to consider as there’s more risk involved. Apply nitrogen as a starter or 2X2 with corn when planting green to help with nitrogen tie-up. Some prefer to wait for the corn or soybean seed to germinate before terminating the cover crop while others terminate the same day as planting. If irrigation is available, have the irrigation system ready to go prior to planting in the event you need to add some moisture into a dry seedbed. Upon planting the field, observe if any adult wheat stem maggot flies are present, and also for the presence of beneficial insects before automatically adding any insecticides in with the herbicide.

Termination of rye occurred closer to heading when wanting greatest biomass in soybean. Roller crimping for termination occurs around pollination. When rye is greater than 12”, consider 15-20 gal/ac of carrier for better coverage. A residual herbicide is helpful at some point. Plan on 0.5-1” of irrigation or rainfall to get the residual to the ground, especially on rye taller than 12”. Some add the residual in with the product used for termination, while others prefer to spray the residual in a second pass once the cover starts dying. Those applying a residual at termination time had irrigated fields and planned on 0.5” irrigation after the rain-fast period. If no rainfall was received in 7 days, they often planned on another 0.5” of irrigation to help move residual down to the soil.

With the quick growth this year, it may be wise to have a Plan A and Plan B in mind if you plan on planting green but the cover crop is getting taller than you are comfortable with, especially for corn. For example, Plan A may be that you’re planning on planting green unless the cover is X inches tall by a certain date (ex. April 5-15), upon which you will choose to terminate pre-plant instead (Plan B). There’s no one size fits all approach, so feel free to call and talk through this if you prefer.

2024 National Ag Week

Happy National Ag Week! What happens in ag impacts all Nebraskans as 1 in 4 Nebraska jobs are connected to ag. A strong ag economy (Nebraska ranks #1 in farm cash receipts of all commodities/capita) helps Nebraska’s overall economy. “In 2021, every dollar in agricultural exports generated $1.07 in economic activities such as transportation, financing, warehousing and production. Nebraska’s $9.98 billion in agricultural exports in 2022 translates into $10.68 billion in additional economic activity.” Also, 92% of Nebraska’s land is used for farming and ranching to grow the food, fiber, and fuel we rely on each day. In 2023, Nebraska had 44,400 farms and ranches, the average size of which was 991 acres. The following are from the 2024 Ag Facts card: https://nda.nebraska.gov/facts.pdf. Thank you to all who are involved ag-related careers and there’s numerous opportunities for youth to pursue ag-related careers!

#1: Nebraska’s largest ag sector is beef production with Nebraska leading the nation in commercial cattle slaughter at 6.8 million head. We moved up to #1 in beef and veal exports. We also have the most irrigated acres in the nation. #2 in all cattle and calves, all cattle on feed, and commercial red meat production.

#1: Nebraska also ranks 1st in Great Northern bean production, 2nd for pinto bean production and 4th in the nation for all dry edible bean, dry edible peas, and light red kidney bean production.

#2: Nebraska is #2 in ethanol production capacity. Nebraska produces 2.3 billion gallons of ethanol annually from 24 ethanol plants. Distillers grains, a co-product of ethanol production, is an important livestock feed. Nebraska is also #2 in bison production. We fell to #2 in popcorn production in 2023.  We are also #2 in no-till cropland acres.

#3: Nebraska is #3 in corn production and exports; also, in cash receipts of all farm commodities.

#4-7: Nebraska is ranked #4 in hay production, land in farms and ranches, and for cover crop acres. We rank 5th in soybean exports and 6th in soybean production. We also rank 5th in grain sorghum, alfalfa hay, and sunflower production and 5th in the nation for production of sugar beets, with half of U.S. sugar production coming from sugar beets. Nebraska is 6th for all hogs and pigs on farms and in commercial hog slaughter. Nebraska ranks 7th in pastureland acres.

Nebraska is the 14th largest winter wheat producing state. We are ranked 14th for organic cropland acres.

When it comes to our natural resources, the aquifer below us is a blessing for irrigated agriculture. “If it was poured over the surface of the state, the water in those aquifers would have a depth of 37.9 feet”. Nebraska has nearly 80,000 miles of rivers and streams and 22 million acres of range and pasture, half of which are in the Sandhills.

There’s so much to be proud of regarding agriculture in Nebraska! As we’re seeing throughout the world, we can’t take farming and food production for granted. May we seek to celebrate and support ag now and in the future! Happy National Ag Week!

Earliness of Spring: Several have commented the tree buds and flowering bulbs seem early. According to the USA National Phenological Network, Omaha, NE is 20 days ahead for spring leaf out of lilacs and honeysuckles compared to the 1991-2020 long-term average, which means we’re currently earlier than 2012 at this point. We’ll have to watch what happens.

Celebrating and Supporting Ag

For the next two weeks, in celebration of National Ag Week (March 17-23), I’m going to share info. on celebrating and supporting the importance of agriculture to Nebraska and, this week, focus on the local area I serve.

There are various events in area counties to celebrate the legacy and achievements of farmers, livestock producers, and those involved in the ag industry. These include area Corn Grower and Cattlemen Banquets, Ag Hall of Fame inductees, and various commodity and agribusiness awards. One such event is upcoming with the Seward Co. Ag Banquet to be held March 18th at the Fairgrounds in Seward (5:30 p.m. social hour, 6:30 p.m. prime rib meal and program). Recognized this year with the Kiwanis Club of Seward Outstanding Farm Family Award will be Hamling Family Farms. The 2024 SCCDP Agribusiness Award recipient is Fehlhafer’s Inc., Ewald and Edith Fehlhafer. Congratulations! If you’re interested in attending, please contact Nick Bauer (402-429-6119) or Shelly Hansen (402-643-3636) to reserve tickets which are $35. It’s a great night to gather as the ag and area community to support and celebrate ag! And, as I think about all the challenges our farm families have faced the past 5 years (flooding, bomb cyclone, blizzards, covid, windstorms, hailstorms, drought, selling off cattle herds, tight economics…), I also see these events as opportunities to gather in community to support and encourage each other in times of hardship and in the making it through. Would encourage all of us to intentionally seek to support and encourage each other this coming year and to reach out when we need to talk!

Since the 1960’s over 10,000 Nebraska farm families have been recognized as Pioneer Farm Families (100 years old) and Heritage Farm Families (150 years old). The legacy of these family farms to survive that many years through all the changes and difficulties in ag is something to be celebrated! Please visit: https://aksarben.org/farm-family-awards/ to read some of the stories or if you’re a farm family who’d like to apply for one of these awards.

Since 2000, Nebraska has ranked #3 in U.S. Corn production behind Iowa (#1) and Illinois (#2) every year but 2002 and 2022. In those two years, Minnesota was #3 and we were #4. That just shows the tremendous impact that drought in Nebraska (2002) and the significant hail to the York/Seward/Hamilton/Clay/Fillmore/Adams county areas had (2022).

The land in this part of the State I serve is extremely productive! Honestly, I appreciated this statement more upon taking thousands of soil samples as part of on-farm research projects through the years.

These soils and productivity contribute to a strong seed corn industry and several industry and independent research companies in this part of the State. When looking at top corn-producing counties in the U.S., York and Hamilton often rise to the top in Nebraska. In 2020, York was the #8 corn-producing county in the U.S. and Hamilton was #11. In the 2017 census of ag, York was the top corn producing county in Nebraska followed by Hamilton Co. Windstorms and hail have impacted the ratings for York Co. the past few years. Details from the 2022 census of ag are to be released throughout 2024. Crop rotation is also important over time (2000-2023) which impact corn ratings but York and Hamilton have remained strong in U.S. corn production throughout that time period often ranking in the top 10-25 U.S. counties.

As an ag educator serving Nebraskans for nearly 20 years, I’m so grateful for the farm families I have the opportunity to serve each day and for the businesses supporting ag! As I think about the future of agriculture and the challenges we face locally and nationally, I’m concerned yet hopeful. There’s many unknowns, outside influences, difficult decisions, and much outside of our control. My hope and prayer is that the people in our rural and urban communities will choose to appreciate, celebrate, support, and protect the importance of agriculture to the economies, well-being, and stability of our local communities, counties, state, and nation.

Soybean Seed Treatments

Appreciated everyone who attended and shared at our on-farm research update in York last week! I’m so grateful to all the farmer-cooperators who have worked with me through the years and who continue to do so! We wouldn’t have as much innovative and practical research without them!

Soybean Seed Treatment Comparison: This week sharing on a soybean seed treatment study. Some producers are interested in alternative methods of protecting seed from insects and disease beyond traditional insecticide/fungicide seed treatments. This can be due to cost, impacts to pollinators, soil microbes and the environment, and/or human safety.

The grower tested three fields in York, Seward, and Hamilton counties via a split planter design for a total of 21 reps. The biological seed treatment consisted of a blend of: 2 oz PhycoTerra® ST, 1 oz Heads Up®, 1 oz N-Gage Ultra ST, 0.75 oz Bio ST VPH in 100 gal solution. In a second tank, 2 oz of Exceed Soybean inoculant was used per 100 gal. The biological seed treatment was applied by the grower. Cost was $9.20/ac for the full biological seed treatment.

The biological seed treatment was compared to Pioneer’s full seed treatment on two fields and Golden Harvest’s full seed treatment on one field. These treatments were applied by the seed dealers. Cost was $28/ac for Pioneer’s seed treatment and $16.63 for Golden Harvest’s seed treatment.

Field 1: Pioneer’s full seed treatment (62 bu/ac) vs. biological seed treatment (61 bu/ac) No difference. Field 2: Pioneer’s full seed treatment (65.7 bu/ac) vs. biological seed treatment (67.1 bu/ac) Significant difference. Field 3: Golden Harvest’s full seed treatment (69 bu/ac) vs. biological seed treatment (68 bu/ac) No difference. Combining the three locations, the standard seed treatment yielded 65.6 bu/ac vs. 65.4 for the biological seed treatment.

Soybeans were planted green into rye in all three fields. The original plan was to roller crimp the rye, but the soybeans were too elongated due to stretching for sunlight in the tall rye and we were concerned about them being damaged with a roller crimper. Irrigation was also necessary to get the soybeans out of the ground and growing with the tall rye in Fields 1 and 2. However, it was interesting for me to see these fields in the summer in a high white mold pressure year, especially in the fields with previous white mold pressure. I never saw white mold impact the soybeans. Any fungal structures on the ground that germinated seemed to be trapped by the rye mat. Biological products like Heads Up® have been shown by other Universities to help reduce white mold and SDS incidence while ILeVO® and Saltro® have been shown to reduce SDS and soybean cyst nematode incidence.

Hopefully this information is helpful for those who are rotating fields to soybeans this year that have had incidence of disease in the past or who are interested in seed treatment options. If you’re interested in trying a seed treatment study for on-farm research, please let me know.

Also, if you didn’t plant rye due to the dry fall, you can consider planting oats this month if you’re growing soybeans this year in a field with SDS and SCN pressure. Oats was the best small grain to reduce the pathogens causing those diseases according to Iowa State research.

Tree Care and Fruit Tree Basics Workshop will be held Sat. March 9 from 10 a.m. to Noon at the 4-H Building in York. Extension Educator Sarah Browning is joining us again! Refreshments will be provided and there is no cost to attend, but registration is requested to Upper Big Blue NRD at 402-362-6601. Bring your questions!

JenREES 2/25/24

Spring Fertilizer: It’s hard to believe March begins this week! With the approaching of March 1st and the nice weather, some may be thinking about fertilizer applications. Three quick reminders:

1-Soil temperatures can be viewed at: https://cropwatch.unl.edu/soiltemperature. Soil temperatures below 50F allow for a slower conversion of ammonium to nitrate by soil microorganisms.
2-There was a high amount of mineralization that occurred last growing season due to the warm soil temperatures. Higher soil residual nitrate was common in soil samples in the area; thus, you can believe the fact that there’s a higher amount of soil residual nitrate and adjust fertilizer recommendations accordingly. If you’re unsure or if the soil samples didn’t pull well due to the dry fall conditions, soil samples can be pulled again this spring to gain confidence in recommendations.
3-Reminder of my nitrogen challenge! The higher residual nitrate provides a great opportunity in putting down a lower base rate and use a tool like sensor based fertigation via Sentinel Fertigation to apply only what the plant says it needs throughout the growing season. You could also consider an on-farm research study using a few different rates. Please let me know if you’re interested in these options.

Pruning Tips: With the coming of March also comes questions regarding pruning. My horticultural colleague, Elizabeth Killinger, shares some tips with some updated research on pruning timing for different plants. Full article: https://huskerhort.com/2024/02/25/a-pruning-primer/#more-1466.

“The first step to pruning is surveying the plant. This will ensure whether or not pruning is needed. Look for and remove any dead, diseased, damaged, rubbing, or crossing branches first. Remove suckers, little saplings at the base of the tree, and water sprouts, small vertical stems on the main branches. Also look at the plant in terms of safety. Be sure the plant is not blocking vehicle sight lines or covering sidewalks. Remove any low hanging branches that are hanging over a sidewalk.

Pruning Tools: In order to make cuts that heal correctly on plants, the proper tools are needed. When pruning small branches, those that are 1” in diameter or smaller, hand pruners are recommended. If you have to twist the pruners or take multiple ‘bites’ at the branch, a different tool is needed. For branches that have a diameter greater than 1”, loppers are recommended. Pruning saws are extremely sharp and work well to get into the tight places that the pruners and loppers don’t fit. They can also cut branches that are larger than 1.5” in diameter. The last tool of the trade is the hedge shears. They are used for shearing hedges or shaping plants and shouldn’t be used as substitutes for other pruning equipment.

Deciduous shade trees, It was previously recommended the best time to prune most shade trees was during winter dormancy. New research shows the optimum time to prune living branches is late spring and early summer because pruning at this time promotes the quickest sealing of pruning wounds, known as CODIT or Compartmentalization of Decay in Trees. Late spring and early summer is when tree cells are most active during the growing season, hence sealing occurs the quickest. 

Evergreen Trees keep their leaves throughout the winter. Pine trees rarely need to be pruned, if you choose to do so it is best done June into July, or when the new growth is between half and fully grown. If pine trees are pruned too early, the tree could be deformed and pruning too late could cause the tree to be stunted. Be sure to prune only the current years’ growth. If the trees are pruned too far back onto older growth, new growth will be delayed a year. Spruce and fir are two evergreen trees that rarely need pruning. If pruning is needed, they can be pruned between November and April.

Evergreen Shrubs, like arborvitae, Japanese yew, and juniper, are best pruned in late winter between November and April. The cuts will heal quickly and will be covered by new growth.

Deciduous Shrub pruning depends on blooming time. If the shrub blooms in the spring, before June 15th, wait to prune until after it flowers. Lilac, forsythia, and dogwoods are considered spring bloomers. If the shrub is a summer bloomer, like a potentilla, flowering quince, or privet, then late winter to early spring is the best time to prune.”

This week sharing on some additional February meetings. Our last Friday February conversation occurs this Friday Feb. 23 on the topic of pesticide resistance and integrated pest management. Dr. Matheus Ribeiro and Dr. Travis (TJ) Prochaska are going to lead us in discussion sharing insights from research and experience. If you’re dealing with pest (weed/insect/disease) issues in a particular field and interested in the topic of resistance management, this conversation will be of interest and helpful. It will be from 10-noon at the 4-H Bldg in York. Please let me know if you’re interested in attending (402-362-5508).

On-Farm Research Updates begin this week depending on which location works best for you. At these meetings, the farmers share on the research they conducted with Extension. That along with the discussion is what makes this meeting so meaningful and one of my favorite winter meetings. Topics include: nutrient management studies, biological products, cultural practices, cover crops, product and production practice studies, RegenAg, and include studies using the latest precision ag technologies. The meetings at all locations begin at 9 a.m. (Registration at 8:30 a.m.). Locations include: ENREEC near Mead (Feb. 20); Beatrice Holiday Inn (Feb. 21); York at Holthus Convention Center (Feb. 27); and Kearney at the Extension Office (Feb. 28).

The 2024 Nebraska Extension Soil Health Conferences are being held at two locations this year: West Point at the Nielsen Community Center on Feb. 29 and the Fairgrounds in Hastings on March 5th. Speakers differ for the two conferences but the themes of leading researchers sharing, farmers and industry panel discussions, networking opportunities, and exhibitor area will be at both locations. At the Hastings location, I’ll be sharing our on-farm research efforts with using clover in corn/soybeans with two farmers: Mike Spray of Clay Center and Jay Goertzen of Henderson. The conferences begin at 9 a.m. (Registration at 8:30 a.m.) and CCA credits are available. There is no charge but RSVP is needed for lunch. You can find more details on the speakers and can register at:  https://extension.unl.edu/statewide/enreec/nebraska-soil-health-conference/.

Regenerative Ag Conference will be held Feb. 28th at Concordia University in Seward at the Janzow Campus Center Cattle Conference Room (Building #21 on Campus Map). The program begins at 9 a.m. (Registration at 8:30 a.m.). This event for producers and crop consultants will be an opportunity to learn about regenerative ag practices, what funding is available for these practices, and how to utilize them to be more profitable and sustainable. It will feature speaker Mitchell Hora, farmer and CEO of Continuum Ag, Keith Berns of Green Cover Seed, and a farmer panel: Dennis Fitzke (Edgar), Aaron Studebaker (Davey), and James ‘Hank’ McGowan (McCool Junction). The day will also include a screening of the film To Which We Belong. It’s hosted by the Upper Big Blue, Little BlueLower Big Blue, and Lower Platte South NRDs, in collaboration with Green Cover Seed. There is no charge but RSVP is needed as space is limited: https://www.upperbigblue.org/regenerative-ag.

Returning to the Farm is a workshop series for families who are in the transition process of bringing members back to the farm or ranch. It’s one of the more important programs Extension offers and I can say it was helpful for me and my family to attend. It will begin with a two-day workshop in Kearney for multi-generational families on March 8 and 9 at the office of Nebraska Extension in Buffalo County, 1400 E 34th St. The series assists families and agricultural operations with developing financial plans and successful working arrangements to meet their unique needs. It will guide families in developing estate and transition plans, setting personal and professional goals, and improving the communication process between family members. The workshop fee is $75 per person on or before March 1. March 2, the fee increases to $85 per person. Registration includes dinner on March 8 and lunch on March 9; it also includes two follow-up virtual workshops. More info. and registration at: https://cap.unl.edu/rtf24.






2024 Farm Bill Decisions

Perhaps this year’s farm bill election decision takes more thought than in the past. Part of this is because the reference price for PLC (Price Loss Coverage) and ARC-CO (Agriculture Risk Coverage) finally increased (due to a couple of higher marketing year average prices with only the highest year being thrown out for the Olympic average). Thus, the trigger potential increases. Most of the decisions could really go either way depending on what happens and how you wish to manage risk. ARC-CO will often trigger faster with a higher price and lower yields, but the maximum payment caps out faster. PLC, when triggered, provides greater payments faster. There’s also the potential of using Supplemental Coverage Option (SCO) via crop insurance with PLC, which was very attractive for some producers in non-irrigated situations hit by drought last year. It could be worth your time to read this article from K-State on SCO and ECO (Enhanced Coverage Option): https://agmanager.info/crop-insurance/crop-insurance-papers-and-information/supplemental-coverage-option-sco-and-enhanced if you’re not familiar with these options. Sign up deadline with FSA for farm bill decisions and with Crop insurance for those decisions are both March 15.

PLC effective reference prices for 2024 are:
Corn: $4.01; Beans: $9.26; Wheat: $5.50 (stayed the same); Grain Sorghum: $4.06

ARC-CO effective references prices for 2024 are:
Corn: $4.17; Beans: $9.56; Wheat: $5.34; Grain Sorghum: $4.31

Projected Prices for 2024 based on projections from FAPRI as of August 2023:
Corn: $4.47; Beans: $10.94; Wheat: $6.38; Grain Sorghum: $4.31

So, at first glance, comparing the prices for each commodity, ARC-CO triggers first for all crops except for wheat when county average yields are maintained. In fact, for those with milo base acres, ARC-CO would already trigger with current projected price and the ARC-CO effective reference price of $4.31.

If you want to protect yield variation, ARC provides protection sooner than PLC. If you want protection for lower prices, PLC provides larger payments once it triggers.

It also depends on crop insurance. For example, if you choose 75% revenue protection and want to add SCO on top up to 86%, then you need to take PLC as SCO is not available with ARC.

Another thought that I’ve often brought up, although it’s not feasible for everyone, is to consider splitting your risk. Corn, to me, is the harder decision here that could go either way. If you have a field or two with higher PLC proven yields, then perhaps consider a few farms in PLC and a few others in ARC-CO to split your risk and provide some protection to you whether either program triggers. It also helps split risk regarding payment caps should they be hit. Some helpful resources are included below:

Upcoming Events: Friday (16th) conversation on economics of RegenAg from 10-noon at 4-H Bldg in York. RegenAg Conf. Feb. 28th at Concordia College in Seward (RSVP to 402-362-6601). On-Farm Research Update in York at Holthus Convention Center Feb. 27th (RSVP: https://go.unl.edu/bhdw). Also, York County Corn Growers is having our tour on Feb. 21st (RSVP to 402-362-5508 if interested).


This example is York Co. irrigated corn. Decision can go either way depending on if you want to protect yield or price. ARC-Co will trigger sooner at $4.17 price with county average yields and if yields are lower at higher prices. PLC kicks in at price of $4.01 with payment greater than ARC if you think price will get down to $3.36.
This example is York Co. irrigated beans. ARC-Co triggers at $9.56 with county average yields and with lower yields/higher prices. PLC kicks in at $9.26. PLC payments beat ARC if price gets to $7.75.
This example is Seward Co. non-irrigated corn. ARC kicks in at $4.17 with county average yields and at higher prices with lower yields. PLC kicks in at $4.01 and doesn’t have larger payments than ARC till $3.50 price. Some growers were also comparing this to using SCO with PLC on non-irrigated ground.
Seward Co. non-irrigated beans. ARC kicks in at $9.56 at county average yield and sooner for lower yield and higher prices. PLC kicks in at $9.26 and has greater payments if price of $7.97 is received. Some growers were also comparing this to using SCO with PLC on non-irrigated ground.
Wheat is interesting. PLC kicks in first at a price of $5.50 with average yields compared to $5.34 with ARC. If you’re in a drought area and expect lower yields with higher prices, ARC will then start triggering first. PLC payments are higher than ARC if price hits $4.78.
Grain sorghum is also interesting. In this example, an ARC payment already triggers if expected price of $4.31 holds true at county average yields. Higher prices at lower yields also triggers ARC. PLC kicks in when price hits $4.06 and provides payments higher than ARC if price goes down to $3.39.
