Seward County Ag Banquet: The Kiwanis Club of Seward partnered with SCCDP and Seward Co. Ag. Society will honor Seward County Ag Leaders on Monday, March 20, 2023 with the 55th Annual Agriculture Recognition Banquet at the Ag Pavilion at the Seward Co. Fairgrounds. Social hour with wine, cheese, beer, and music will be at 5:30 p.m. with the prime rib meal and program to follow at 6:30 p.m. The cost to attend the banquet is $30.00 per person. Please contact Pam Moravec (402-643-7748) or Shelly Hansen (402-643-3636) to reserve your seat. The Kiwanis Club of Seward will use the proceeds from the event to support the youth of Seward County through a variety of programs and events.
Nitrogen Rate Studies: As growers consider pre-plant nitrogen applications this year, there’s opportunity to consider a variety of nitrogen rates to test any impacts on one’s own field(s). I covered the results of some area studies comparing rates of 50 lb N/ac nitrogen differences in an earlier article. One can easily test this for yourself in a field by either using field-length blocks as those studies did, or with the use of precision ag technologies, prescriptions can be written to try different N rate blocks that are smaller in scale (300’ long by 30’ or so wide). These blocks can then be repeated throughout areas of the field with different soil types and topography. I have an example at jenreesources.com of what this looked like from studies last year. Please let me know if you’re interested in testing this. The 2022 on-farm research results can be viewed at: https://onfarmresearch.unl.edu/.
Perennial cover crops: Several weeks ago, I shared our research on interseeding cover crops into early season corn and soybeans and said I’d share our next steps in a future column. One goal of the cooperators was to achieve a living cover that survived into the next growing season. When we saw that interseeded red clover established in soybeans and survived the following spring, we got excited about the possibility of more intentionally growing clovers as a perennial cover crop.
In March of 2022, six sites were dormant seeded with either Mammoth red clover (tall), Medium red clover, or Dutch white clover (low-growing, aggressive like clover in lawns). The clover eventually emerged at all the locations. All but two sites were lost due to the dry spring or June 14 hailstorms. Two sites in Clay County survived the June 7th hailstorm. The grower at those sites chose the Mammoth red clover. It was dormant seeded in March using a drill interseeder into cereal rye. The cereal rye was killed with 10 oz/ac clethodim prior to planting corn and after planting soybean. Once the clover had emerged and was at least 1” tall, Zidua was used in both the corn/clover and soybean/clover areas and was used again 3-4 weeks later. The check areas in the corn and soybean used the grower’s full herbicide program.
The clover provided excellent weed control in the corn. It had good weed control in the soybean with velvetleaf, sunflower, and lambsquarters being the predominant weed species. Biomass samples of the clover prior to harvest showed 30 lb N/ac available. Samples will be taken again this spring. The soybean without clover out-yielded the soybean with clover (74 bu/ac vs. 68 bu/ac). It also economically did better this first year. The ultimate goal is to get something living between the rows for reducing chemical and nitrogen inputs, providing a grazing benefit, and determining impacts to yields and economics over several years. We currently have 9 growers planning on some type of clover study in 2023. If anyone is interested, the easiest way to try this is just dormant seeding this March (can drill or broadcast) clover in 5+ acre blocks leaving a check block between the clover blocks and checks on either side. I will work with you on the combine passes to get the replications. This year the farmers are trying AberLasting clover (Dutch white X Kura), Dutch White + Medium Red, or Mammoth red clover. We also have a couple of growers trying AberLasting with either bluegrass or buffalograss. The simpler design being used by the growers is on my blog. This is a different way of thinking, in some ways going back to what our ancestors did only with today’s hybrids and varieties. These growers are desirous to find ways to reduce inputs on their own farms for the future. Please let me know if you’re interested in trying this too.
The above designs are just some ideas for doing nitrogen rate prescriptions by soil type/topography or field-length strips.
10 lb/ac Mammoth red clover was dormant drill seeded March 2022 into cereal rye. A shot of rain in the spring helped it get established. The grower felt it was more successful establishing the clover into old soybean ground prior to the corn crop. The cereal rye was terminated with clethodim around 10 days prior to corn planting. Once the clover was up 1″, Zidua was applied to the field (other Group 15 herbicides could be used instead). He used Zidua again 3-4 weeks later. The corn with the clover had excellent weed control as did his check treatment which used a full corn herbicide program. The clover got about 2.5′ tall and then laid down. We couldn’t take this study via on-farm research because two different hybrids were used across the clover/check area. He moved over with strip till rig in the fall and took out some of the clover, but quite a bit still remained. Soybeans will be planted in this field next year and the plan is to maintain the clover in the strips without needing to reseed anything.
10 lb/ac Mammoth red clover was dormant drill seeded into cereal rye in March 2022. A timely shot of rain helped with establishment. Soybeans were planted green into the field. The rye was then terminated with 10 oz/ac of clethodim and Zidua was applied when clover was at least 1″ tall (other Group 15 herbicides could be used instead). Zidua was applied again 3-4 weeks later. A June 7, 2022 hailstorm damaged the soybean and clover with the clover recovering faster than the soybean. The Mammoth red clover gets tall and it looked kind of interesting in September to see the soybeans holding the clover up so it could reach sunlight. When soybean leaves started senescing, the clover started forming more of a mat. Primary weed species were velvetleaf, sunflower, lambsquarters (weed species shift from predominantly waterhemp/palmer). This field has a history of being very clean. At harvest, the combine didn’t seem to have much issue harvesting it and the grower had combine set well so there wasn’t green material going into the tank. The field smelled like fresh cut alfalfa after harvest. The grower strip tills in the fall and moved the strip to the side of the old row, taking out some of the clover. Corn will be planted into those strips this spring with the goal of maintaining the clover without seeding any additional clover.
Been hearing reports from our cattle producers about calf loss prior to birth and also after birth. Wet hair coats, low air temps with the windchills we’ve experienced have been brutal. We would recommend reporting your losses. We realize that the Livestock Indemnity Program has criteria for wind chills that may not have been met for each part of the State. However, the unusual weather events this year compounded upon each other led to a very extreme winter and we feel additional factors should be considered. Some Farm Service Agency (FSA) offices have contacted us for additional considerations as well. There’s a team of us working together on this and we hope to release information for consideration by local Farm Service Agency offices and others.
Tyler Williams, Extension Educator in Lancaster County who specializes in weather, shared the following stats with the team of us working on the additional considerations for FSA. Since February 1st:
- Above normal snowfall: 5” (West) to 20” (East) above normal
- Total Snowfall at least 10” for most of Nebraska – Eastern Nebraska 20-30”
- Average temperature was 10°F North/East and 20°F South/West
- Min temps were 10-15°F below normal, Max Temps 10-20°F below normal
- 20 (Southwest) to 30 (Northeast) days the max temp was below freezing
- 6-10 (South) to 20-24 (North) Days the temp dropped below zero
- 10-15 days with measurable precipitation
In the last two weeks:
- Minimum temps dropped to 20 below Central and West, 6-12 below East
- 4-6 (North) to 7-11 (South) days with min temp above zero i.e. 8-10 (North) to 3-7 (South) days the temp dropped below 0
- 4-7 days with measurable precipitation – Almost every other day
- 0 days temps were above 32°F, except for NE/KS border and Southwest Panhandle
- Snowfall 2 (Southwest) to 10 (Central/East Central) inches above normal
- Snowfall ranged from 2-4” in Southwest and Northeast to 7-12+ in Northwest, Central and East Nebraska
- Wind chills dropped to 20-30°F below zero
- Cattle comfort index in “extreme” category
I know a lot of crop farmers have been concerned about field work and how far behind they feel due to the fall. Right now our livestock producers could really use some encouragement too with the brutal calving season, ice/snow covered stalks, high hay prices and blowing through feed with the added energy requirements due to the cold. Another thing that put this winter into perspective for me was seeing the tornado damage in parts of the U.S. There’s just been a lot of crazy weather! Al Dutcher’s forecast doesn’t sound great for the next few weeks either and I realize our next challenges may include potential flooding and muddy lots. However, for now, just seeing the sun shine does wonders in lifting my spirits and have heard several others remark on this too!
