Start the Season Right by Planting the Right Genetics
With the 2022 planting season right around the corner, it’s time to focus on the one thing that will help you capture the most ROI in each field.
Field-by-field product placement is key to maximizing yield – and in turn – profit. Research shows plant genetics account for a 20% difference in yield. This means you could raise 12 more bushels of soybeans and 40 more bushels of corn PER ACRE simply by paying closer attention to your crop placement.
Below are three factors to consider when double-checking your crop placement for 2022:
- Study Field x Field® Ratings. Look at the Field x Field Ratings in the Latham® Product Guide for corn and soybeans. These charts simplify where you should place hybrids and varieties. A “1” rating means it’s a great fit for a particular environment; a “3” rating means you should not plant that product if your field conditions match that description. Your Latham Dealer has seen most of our products in environments, so call him or her if you have additional questions about where to place a particular product.
- Stick to the plan. If your seed dealer has provided you with a Field x Field plan, organize your seed shed so you can stick to the plan. Subscribers to Latham Seeds’ Data Forward® program receive a crop plan book, which you can keep in your planter tractor. It’s a good practice to double check that the right seed gets in the planter. If planting conditions change in a particular field, then take the time to move products. It will be worth an hour of your time to capture the extra $150 to 200 per acre in profit potential.
- Match Genetics to Management. If a certain corn product is described as “likes high management,” then you should not place that product in a field with poor fertility levels. Your seed dealer may not know your fields’ fertility levels unless you share it. That information is critical for accurate product placement as some genetics can handle tough fertility situations and others will fall apart in those environments. Also make sure you aren’t overplanting or underplanting each hybrid. Look at the “suggested populations” in our Product Guide, as well as the “Ear Type” rating and our stress wheel poster. We want to help you capture yield!
If you’re planting soybeans early or at the same time your planting corn, treat the seed with SoyShield® to protect it from early season fungal diseases. Seed treatment also gives seedings an early advantage. Even when using a quality seed treatment, plant fields with the heavy soils that remain wet and cold last or at least the soils have warmed. This will help your soybeans better ward off root diseases all season long.
A successful 2022 crop year begins with having a plan and sticking to it! Take the time now to double-check that you properly matched plant genetics with soil conditions. Our dealers are also happy to talk through field placement as well. If you have further questions or want to chat with our agronomists call: 1.877.GO.LATHAM (1.877.465.2842).

Balanced Fertility to Optimize Yield
High yields from 2021 combined with increasingly high fertilizer for spring 2022 have caused many farmers to scale back their fertilizer applications. While they may save on short-term input costs, they could lose more in yield than they’re saving.
Spending lots of money on fertilizer doesn’t equal high yields, however, having a soil balance sustains a corn or soybean crop during a tough year. So how can you strike a balance? It’s important to start with pH, especially when growing legumes like soybeans, edible beans and alfalfa.
A soil pH around 6.5 is important because it determines if nutrients are in usable form for the crop. If you struggle with high pH, fertilizers like MAP and AMS that are more acidifying will help lower pH over time. The micronutrient part of your fertility is also very important. In most cases, you don’t need to add as many micronutrients to fix a low test; you just need to be aware of which nutrients may be too high and thus limit the availability of other nutrients.
Soil biology – fungi, bacteria, and other microbes – play a key role in cycling nutrients to available and unavailable forms. It’s more about having a balance and being in the right form than it is about applying lots of fertilizer. For example, Iron Deficiency Chlorosis (IDC) in soybeans results when iron is not in an available form for the plant to take it up; there is actually over 20,000lbs/acre of iron in the top 8 inches of our soils!
A 200-bushel corn crop removes approximately 150, 70, and 50 pounds of N, P, and K respectively per season. A 60 bushel per acre (bu/A) soybean crop removes approximately 240, 50, and 75 pounds of N, P, and K per season. Do we need to apply exactly those amounts? No, but we must understand what the soil can provide and how it maintains a balance that is available to our crops. Soil testing is so important for gaining this understanding. When problem spots arise, then we tissue test, take additional soil samples, and use other information to diagnose.
The key point is a lot more goes into maintaining a balance in your soils than just applying the same amount of fertilizer every year. The best place to start is with a soil test. Latham’s Data ForwardTM program helps takes some of the worry and complexity out of it while figuring out what your soils needs. Remember, your soils are not identical to your neighbors’. A soil test is key to finding the right balance for higher yields on your fields. I’d be happy to discuss with you any questions you have about your soil and how Latham’s Data ForwardTM could help you iron out your fertilizer needs. Call 1.877.GO.LATHAM (1.877.465.2842).

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:
- 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® IRONCLADTM variety 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.
- 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.
- 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 ForwardTM 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! -

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:
- 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.
- 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.
- 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.
