Yield Reports are Encouraging
As we were conducting our pre-harvest field inspections, many production growers said they’d be happy with 40-bushel yields due to the early cold spell followed by drought. I’m happy to report that most of our growers’ yields were in the mid-50s to the mid-60s, and some even saw yields of 70 bushels per acre (bu/A) or more!

It seems that a few timely rains in August made the difference between having a decent crop and having a poor one. Below are raw yield results from some soybean Latham® Showcase plots and Latham Elite trials harvested this fall:
- Near Chatfield, Minn., Latham® L 2193 E3 yielded an outstanding 107.8 bu/A, and L 2049 E3 was right there with 95.7 bu/A!
- Near Sac City, Iowa, L 2283 XF brought in 84.39 bu/A and L 2184 R2X was a close second with 82.87 bu/A.
- Near Oskaloosa, Iowa, L 3448 R2X produced 83.52 bu/A, barely nudging out L 3479 E3 at 83.26 bu/A.
- Near Lu Verne, IA, L 2049 E3 topped a plot with 81.89 bu/A and L 2379 E3 came in at 79.79 bu/A.
- Near Albert City, Iowa, L 2458 E3 yielded 91.94 bu/A and L 1648 LLGT27 came in at 81.49 bu/A.
- Near Vernon Center, Minn., L 1758 E3 scored 75.15 bu/A and L 1769 R2X came in at 73.21 bu/A.
- Near Renville, Minn., L 1758 E3 scored 75.06 bu/A while L 2049 E3 was very close with 73.11 bu/A.
- Near Clarence, Iowa, L 3192 E3 produced 120.12 bu/A and L 2894 E3 yielded 110.85!
- Mantador, ND, caught some much-needed rain late in the season. At that location, L 1094 E3 produced 79.19 bu/A and L 0739 R2X yielded 65.19 bu/A.

3 Ways to Maximize Soil Tests
To save the most money on inputs, we must plan earlier and earlier every year. A current soil test is the best way to evaluate your fertility and ultimately your yield potential. Besides the normal evaluation of the main nutrients, a soil test pays for itself.

Let’s look at three ways to use your soil test to its full potential:
1. Soil pH matters in more ways than lime. We typically look at pH maps to understand nutrient availability, but let’s think in terms of input planning. Take soybeans and a pH map, for example. By looking at this one map you will better understand the areas of high pH, so you can select a Latham® IRONCLAD^TMvariety to stand up to challenges from Iron Deficiency Chlorosis (IDC). Another great use for this map is herbicide applications. Herbicide carryover in high pH spots can impact soybean yields. This map potentially can help make the decision to change a crop rotation or herbicide program to save yield losses.
2. Organic Matter is king. Do you have organic matter (OM) readings higher than 5% and below 2% in the same field? Couple this with yield and this is a great start to help apply nitrogen more accurately. Another great combination is OM beside soil type map. Look at Latham Seeds’ product guide while you’re looking at these maps to quickly determine what percent of each field would benefit more from defensive traits or offensive traits. Really high OM soils typically hold more water and have challenges like flooding and higher disease potential. Also notice how much higher your potassium (P) and phosphorus (K) levels are in these spots.
3. When phosphorus levels are high, other nutrients are lacking. Many farmers use animal manure as a source of fertilizer. This is great because it provides most of the essential nutrients our crops need, however, manure can have higher levels of some nutrients including phosphorus. If your soil potassium levels are climbing, move manure applications to another field. Also pay attention to other nutrients that suffer when potassium increase. If you notice your P levels are high, then Sulfur (S) and Zinc (Zn) could be at a disadvantage. Both S and Zn can be less available to the plant as P levels climb. This may not be visually noticeable at first, but it will show up in growth and yield if you do a side by side with S and Zn fertilizer.
These comparisons and maps can be done in Latham’s Data Forward^TM app with a simple soil sample taken and yield map to start seeing value out of the information that you capture every year. If you’d like to learn how to start putting these things to work on your farm give me a call!

Latham Hi‑Tech Alfalfa: Higher Quality. Greater Yield. Better Nutrition.
Farming is like dancing with Mother Nature, and Mother Nature always leads. We can’t control the weather, but we can manage around the risk.

Understanding a seed product’s features and benefits is powerful tool to help reduce production risks. Alfalfa from Latham Hi‑Tech Seeds provides growers with options to better place the best genetics for certain soils to enable a product to perform at its best.

With this in mind, let’s review some of Latham’s top alfalfa products:
- Features of LH 9120: branch root expression and finer stems.
  Benefits: LH 9120 can be planted on wetter soils. If conditions remain wet, the plant will respond with several branching roots instead of one major tap root. NOTE: Alfalfa usually has a singular tap root. In a water-logged situation, alfalfa with a tap root will not survive as long alfalfa with a branch root. Branch rooting give additional support by bringing several roots closer to the surface of the soil, allowing for better respiration. Additionally, 9120 has a finer stem. Finer stemmed alfalfas tend to dry quicker for baling.
- Features of LH 9700: disease resistance, unparalleled recovery after cutting and multi-foliate expression.
  Benefits: LH 9700 is a very powerful, high horsepower type of alfalfa protected with disease resistance. It protects the plant, giving it the best chance of long-term stand. Quick recovery after cutting means the crown buds produce new leaves quickly. Leaves catch the sun, build essential carbohydrates for the crown, and generate more yield and better quality. I relate each leaf to a cylinder in an engine. As we add cylinders to an engine, it adds more horsepower for better performance. It’s the same with alfalfa; more leaves equal more energy to produce top yields and superior quality.
- Features of America’s Alfalfa AA 481 RR/HarvXtra: low lignin, Roundup® resistance, and high disease resistance.
  Benefits: Reduced lignin helps AA 481 RR/HarvXtra achieve better fiber digestibility. When compared to conventional alfalfa, research has shown to deliver 14 to 18 % relative forage quality (RFQ). Higher quality forage nourishes the animal, so it gains valuable feed efficiency and that leads to higher profitability. Additional benefits include harvest flexibility of seven to 10 days while maintaining excellence in quality and producing as much as 20% more yield. This is helpful to help manage around weather events. Roundup Ready benefits include keeping fields clean, improving forage quality, reducing weed competition, and extending stand life. This alfalfa product also has high resistance to anthracnose, which can damage stands. HVXRR 481 has HR rating for Race 1 and R rating for Race 5. This product is one of the newest commercial selections for HarvXtra alfalfa with top yield capacity. It also boasts extra yield and stand life, protecting benefits to reduce risks of anthracnose disease.
Latham Hi‑Tech Seeds offers a variety of products, each with special features and benefits. Remember, each seed is treated with Latham’s Alfashield^TM, which gives our seed a competitive advantage by emerging faster, growing strong, and yielding more!

Can You Cut Fertility Costs Without Cutting Yield?
You could lose more than you save if you cut costs in the wrong places.

Some farmers are thinking about cutting back on their fertility program for 2022 crops because fertilizer costs are increasing and pre-order prices aren’t guaranteed into next spring. I understand that price hikes cause uncertainty. As someone who also farms, I feel the same way. What I’ve learned is that fertility is the foundation to keeping a crop healthy all season. Top-performing hybrids need food to fuel their growth.

Below are three questions to ask yourself as you plan your 2022 fertility program:
1. Are you keeping potassium levels up? Potassium (K) is critical for handling drought stress and late-season stalk health. Depending on cation exchange capacity (CEC), you want to see K levels of 150 to 220 parts per million (ppm) on your soil test. North Dakota State University (NDSU) research reveals the type of clay soil (high vs. low shrink swell clay) is key to fertilization. High shrink swell clay soils must be kept at that 200-ppm threshold. When these soils dry out, they hold the K between clay layers much tighter. On soils with low shrink swell potential, the 150-ppm threshold will provide enough K throughout the season. Have you ever noticed how some soils are more forgiving after you accidently cut ruts when it’s a little wet? Note those soils because they hold K tighter, prohibiting your crop from using it.
1. Thinking about cutting back on nitrogen? Nitrogen is more closely tied to yield than any other nutrient. Corn takes up approximately 150 to 300 pounds of nitrogen (N) to reach its full yield potential, but this doesn’t have to all go down as commercial fertilizer. Nitrogen needs depend on several factors including crop rotation, manure application, green manure, and residue management. Consider applying nitrogen in the spring with a nitrification inhibitor on lower CEC soils or if it’s a wet spring. The best practice in the fall is to wait until soil temps are below 50 degrees before applying nitrogen.
1. How are you valuing manure? When comparing fields where manure was applied to fields that only get commercial fertilizer, you realize fertilizer is worth the additional hassle to apply. Microbes in the manure and the biology that feeds on it can build nutrient levels much faster in the soil as compared to commercial fertilizer. It’s important to have a representative manure analysis to know what you are applying.
Remember, every 100 pounds of nitrogen applied requires about 500 pounds of lime to offset the acidity created by the nitrogen conversion process. Make sure your pH is correct, so all the nutrients in your soil are available to your growing crop. Correct soil pH before you try to build your P, K or micronutrients.

Improve Meat and Milk Production with Better Silage
“Repetition is effective. Repetition is effective.” – Legendary Broadcaster Paul Harvey

The massive amounts of information we process each day makes it easy for messages to get diluted or forgotten. That’s why I find it helpful to continually review the basics, especially when it comes to feeding corn silage.

What gets fed to dairy cattle, as well as to beef cattle, affects the quality and quantity of the milk and meat produced. We know there is a correlation between starch and fiber digestibility with rates of gain. Getting the most tonnage and high nutritional concentration gives you the best chance of improving milk quality and production in dairy, as well as rates of gains in beef.

Most of the silage research to date deals with feeding corn silage to dairy cattle. However, Iowa State University has updated its Beef Corn Silage Calculator that ranks the potential value of corn silage varieties used in beef rations.

You also get an index ranking for Latham® hybrids in our seed guide. Our index rating shows a hybrid trend on a multi-season, multi-environment basis. Keep in mind that management practices, weather, and fertility can dramatically impact forage quality.

Simply stated, here’s what we want from corn silage: high tonnage in the field and high quality in the bunk. Listed below are some basic corn silage terms to provide a better understanding of corn silage yield and quality:
1. Dry Matter Basis (DM). Most all feed comparisons are done on a dry matter basis where all the moisture is removed. This helps provide consistency.
2. Corn Silage Composition. Typical corn silage composition is 50% grain to 50 % stover on a dry matter basis.
3. Grain yield. High-yielding grain hybrids tend to bring great tonnage and quality. Yield contributes to tonnage and quality.
4. Nutritional value of the kernel. The value of corn silage is related to its energy content from starch, fat and amino acids. Corn silage provides energy from digestible fiber and from the starch contained in the kernel.
5. Starch Digestibility. Increasing starch digestibility supports rumen bacteria and increases energy supply to dairy and beef cows. It’s estimated that for every 1 percent of fecal starch that passes into the manure, milk production is reduced by 0.72 pounds per head per day. This adds up!
6. Fiber Digestibility. Hybrid selection, environment, and management practices impact fiber digestibility in corn silage. It’s estimated that for every 1 point of increased or improved fiber digestibility, milk output of a dairy cow can improve about one-half pound of milk per day per head.
7. Non-Fiber Carbohydrate (NFC). Corn silage is about 50 percent NFC. Note: There is a correlation between this number and the grain percentage.
There is an ocean of information available from seed guides to feed reports. Ultimately, it comes down to considering the end use first. Match your end use goals with product features and proper placement for maximum ROI at the bunk.

Take the Test and Beat the Pest!

By robbing farmers of more than 100 million bushels annually, Soybean Cyst Nematode (SCN) is estimated to be the #1 yield-robbing soybean pest or disease in the United States. Farmers may scream over lost yield this fall, but SCN is considered a “silent yield robber” due to a lack of above-ground symptoms in most fields.

Immediately after harvest is the best time to take soil samples for SCN. Several universities have programs that offer free soil samples to evaluate SCN, so check with your local Extension office to see if you qualify.

Think SCN isn’t a problem in your fields? Think again! Dry soil conditions, especially early in the growing season, can greatly increase the effects of SCN infestations. I received numerous calls in June and July about yellow, stunted soybeans. Most farmers suspected Iron Deficiency Chlorosis. Upon further inspection, SCN was almost always present and in larger numbers than previously observed. When I asked whether these farmers had taken a recent soil sample for SCN, most had not. They admit to mostly relying on SCN-resistant varieties to control or minimize the losses from this pest.

We have known for years that PI 88788 is gradually losing its efficacy against the pest, and more than 95% of SCN-resistant soybeans in America have PI 88788 as the source of gene resistance. Since 1997, a team of researchers at Iowa State University led by Dr. Greg Tylka has conducted annual in-field trials with hundreds of SCN-resistant varieties. They measure agronomic performance and SCN population densities from planting until after harvest.

Scientists have determined that to be effective, SCN-resistant varieties must maintain less than a 10% reproduction rate of SCN during the growing season. Since 2004, Dr. Tylka and his team have noticed that the average of all PI 88788 varieties in their trials have gradually exceeded that threshold. They have also noted that the average yield of those varieties has decreased as the SCN reproduction has increased. For more information on these studies, visit www.isuscntrials.info. Other land-grant university researchers have reported similar findings.

To effectively manage SCN in the future, soybean breeders are focusing on other sources of gene resistance. Your Latham Soybean Product Team is continually evaluating and searching for opportunities to bring new, better resistant varieties to our lineup. We also are evaluating several seed treatments for battling this pest. Saltro®, our seed treatment product for SDS protection, is also noted to have activity against SCN. More information from our Latham Elite trials will be available post-harvest.

“TAKE THE TEST. BEAT THE PEST.” is a slogan/campaign by The SCN Coalition™ and funded by the Soybean Checkoff and is designed specifically to promote awareness of SCN. These microscopic roundworms, which infect the roots of soybeans and other plants, can be present in a field for years before above-ground symptoms are visible. We encourage you to take the test this season, so you can plan accordingly for the future.
