Fallow Syndrome: Coming Soon to a Corn Field Near You?

The 2019 growing season is mostly in the history books, and for many of us, is one that we are thankful to have behind us. However, 2019 might have one more final shot to take. With the significant acreage that was prevent plant in 2019, some farmers and agronomists are beginning to consider the potential for fallow syndrome in 2020.

Fallow syndrome is not a condition that we routinely encounter in the eastern corn belt. In essence, fallow syndrome is a condition that can occur in fields where a crop was not planted the prior year, and is primarily a problem in grass crops, such as corn or wheat. It manifests as symptoms of a nutrient deficiency, particularly phosphorus, in a field where fertility is adequate. The reason for this condition is a decline in the population of beneficial microorganisms in the soil, such as mycorrhizal fungi. These microorganisms form a symbiotic relationship with the crop plant and enhance the crops ability to uptake nutrients from the soil in exchange for exudates from the roots that feed the microorganisms. In the absence of a suitable host, these microorganism populations decline, and the crop does not become as quickly inoculated as in a year following a crop.

The effects of fallow syndrome will generally be expressed more in fields that were kept clean for most of the prior season, as many weed species are suitable hosts for these microorganisms and will help to preserve their populations. Therefore, if a field was kept sprayed or tilled to limit weed populations, there is more of a risk of fallow syndrome than fields that had weed populations that were not managed or those that were managed by mowing during the season. Also, if a cover crop was planted on a field, fallow syndrome chances are reduced as many cover crop species are suitable hosts for these organisms. One exception to this are brassica species, such as radishes, turnips, or rapeseed, which are not suitable hosts for these microorganisms.

If planning to plant corn in fields that were fallow in 2019, a starter fertilizer application of phosphorus and zinc should be considered, particularly on fields where fertility levels are marginally low. As the root system of the corn plant develops and expands in size, the crop is better able to take in nutrients and the likelihood of these symptoms declines. In addition, microorganism populations will also increase and reestablish the symbiotic relationships within the crop. It is also important to remember that corn plants often exhibit purpling similar to a P deficiency early in the growing season due to the bright, sunny days and cool nights that often occur in the region during the spring.

While fallow syndrome is a real condition, it is unlikely that it will be a major concern for many growers during the 2020 season. As always, sound management is the best tool that we have to deal with this parting shot of 2019.

Hay Quality 2019: Know What You Are Feeding

Don’t Let Thin Livestock Happen Sample, Test, Allocate and Balance from Phil Reid on Vimeo.

University experts across our region are cautioning that the volume and quality of the 2019 hay crop in the barn may not be as good as we think. Delayed harvesting of first cutting resulted in significant declines in hay quality. Overly mature forage plants have higher non-digestible fiber levels and reduced mineral contents and may require the addition of supplements to meet livestock nutritional needs.

 

We have a forage test package available that is specifically designed to meet the Purdue Extension Services recommended test parameters to provide the information needed to ensure proper livestock nutrition this winter.

New Study Reviews Mehlich-3 Extractant

University fertilizer recommendations for Ohio, Indiana, and Michigan (Tri-State) are currently based on the Bray-P1 extractant for phosphorus and the ammonium acetate (AA) extractant for cations. These fertilizer recommendations are currently being revised, and will use the Mehlich-3 soil test extractant as the standard for both phosphorus and potassium. A recently released collaborative research study affirmed that Mehlich-3 phosphorus correlates well with Bray-P and Mehlich-3 cations correlate well with ammonium acetate cations, specifically for soils in the Tri-State region.

A&L Great Lakes Laboratories has been using Mehlich-3 extractant since the early 90's with internally developed conversion equations to report Bray P1 and ammonium acetate values for use with established university fertilizer recommendations. Most production soil laboratories use Mehlich-3 so that phosphorus and cations can be obtained with a single laboratory process.

The agronomy staff at ALGL has been closely following revisions to the Tri-State fertilizer recommendations, and have been working to prepare for the transition to directly reporting Mehlich-3 data upon customer request. If you have any questions, please call your ALGL agronomist to discuss this further. To learn more about how the Mehlich-3 extractant compares to the traditional extractants, you can read the research article here.

Growers not delaying fall tillage long enough to collect soil samples

With the late harvest, growers are pushing hard to get fall tillage completed to address compaction from both last fall and this spring. In some cases, producers are not even waiting for soil sample collection or fertilizer applications.

Fall tillage will leave the soil surface 1-3 inches higher than before the tillage operation. A sampling depth of 6 inches before tillage becomes 7-9 inches due to the reduced density of the tilled soil. Many soil probe designs will push the soil away rather than collect the soil. Collecting a proper depth soil sample becomes nearly impossible. Some sources recommend driving over the soil surface and taking the samples from the tire tracks, this can lead to too deep of a sample.

If any fertilizer was applied prior to the fall tillage being completed, it is recommended to wait until next spring to collect soil samples.

If a field has been tilled before soil samples have been collected, soil sampling needs to be delayed by a minimum of 6 to 8 weeks to allow the soil to settle to a density that can be accurately sampled. The time needed for soils to settle can increase under deep or aggressive fall tillage operations. It is best to wait until next spring to collect samples. Incorrect sampling depth will bias a soil sample much more than the seasonal variability between spring and fall soil samples.

Late Season Plant Tissue Analysis

Collecting plant tissue samples throughout the entire growing season to monitor nutrient levels has become a common practice over the last few years. As most of the crops in our region are now well into later grain-fill stages, plant tissue test results need to be evaluated with a cautious eye.

As plants transition from vegetative growth stages to reproductive stages, the nutrient content of the plant leaves will change, most noticeably nitrogen and potassium. These nutrients are mobile in plants, so as the plant starts transitioning to grain-fill, they may be translocated from the leaf to the grain resulting in low tissue test ratings that may not necessarily indicate a yield-reducing nutrient deficiency.

Another common trend in plant tissue test nutrient levels is an increase in micronutrient concentrations as the plants approach physiological maturity. This is a result of carbohydrates and other carbon-based molecules being translocated from the leaf tissues to the grain effectively reducing the biomass of the leaf. The micronutrients (iron, manganese, zinc, and copper) are immobile in the plant tissue, so they remain in the leaf that has a lower mass and are now present at a higher concentration. The micronutrients may be rated as high or very high, however, this may not be an indicator of excessive fertility or potential toxicity.

While plant tissue testing can be a very effective tool for fine-tuning a fertility program, be careful not to make drastic decisions based on late-season plant tissue test results alone.

UPS RS Label Expiration Dates

UPS RS labels can be printed at any time, and there are no charges associated with the labels until they are used. This means they can be printed in advance and ready to use when you are already to ship. One challenge in printing UPS RS labels too early is that the tracking capabilities for a given label decline 12 – 16 months after creation.

 

The date of creation can be tracked directly on the label. If you are nearing the expiration date printed on the UPS RS labels, you can request new labels by calling/emailing the lab, calling/emailing your ALGL agronomy sales representative, or ordering via our on-line store at www.algreatlakes.com.

2 Easy Steps to Shipping Samples:

1.     Order Boxes – We offer 4 convenient boxes for soil sample shipment. Order the boxes and associated labels online or by calling the lab. You purchase the boxes and we ship them with the labels to you at our cost.

2.     Pack Your Samples – Place the samples in the box so that they will not spill in shipment, tape the box shut, and affix the UPS RS label on the box. The box can be part of your usual UPS pickup, dropped off at a UPS pickup location, or you can call UPS to schedule a pickup. There may be a cost associated with a UPS on site pickup, please inquire with your local UPS representative.

You are not charged for the UPS RS labels until they are scanned by UPS upon pickup. The cost of the shipment is calculated using our discount, and that amount is transferred to your invoice. The cost of the sample analysis and shipping come to you on one invoice.

Keep Your Samples Safe!

With the growing season winding down, many of you are beginning to think ahead to collecting fall soil samples. With the time and effort that you put into collecting those samples, we want to make sure that they arrive safe and sound, and in good condition. Following are some suggestions to ensure that your samples arrive safely and can be processed without delay.

  1. Use appropriate sample containers. Soil samples in paper envelopes and liquid samples in ziplock bags may be lost in shipment. We can provide you with the correct bags, bottles and boxes.
  2. Send a sample that is representative of the material you are testing. Very small and extremely large volumes of samples may affect the analysis results.
  3. Make sure all sample containers are closed and securely fastened. If a sample can spill… it will. 
  4. Include a sample submittal form that lists all of the sample information, reference information, tests requested, special information, and your account number. Submittal forms can be found at algreatlakes.com, or you can contact the laboratory.  
  5. Pack your box carefully. Using the sample submittal form as your packing order can help you identify when a sample is missing before you ship the box.
  6. Use a shipping box that is the right size. Small samples packed in large boxes can bounce around and be damaged in shipment.  Pack open spaces with crumpled newspaper.
  7. Use a shipping box that is rated for the weight that you’re shipping. We receive boxes each year which have broken apart from the weight of the samples.
  8. Protect your back – and ours. Avoid shipping overweight sample boxes.  Our chiropractor will thank you.
  9. Make sure your return address is on the shipping box – even if it is inside one of the box flaps. This can help determine who to contact in case of a problem.
  10. If you are shipping samples in multiple boxes, please mark the boxes 1 of 3, 2 of 3, 3 of 3… this will help the lab technicians get your boxes back together, and will help us determine if a box is missing in shipment.

Helpful Tips for Submitting Fertilizer Samples

Quality analysis begins with a quality sample. When submitting fertilizer materials to the lab for analysis, please remember these helpful suggestions:

  1. Paperwork
  • Send in a completed ‘Fertilizer & Lime Sample Submittal Form’ with your sample.  This can be found on our website at www.algreatlakes.com.   Please be sure to include:
  • Account number. If you do not have an account with us, be sure to add your name, address, and phone number.
  • Email address if you would like your report emailed to you.
  • Analysis that you desire.
  • Approximate Analysis of your fertilizer, if known. This not necessary, but cuts down on the turnaround time by eliminating the need to do preliminary testing to determine which method is most appropriate.

 

  1. Submitting Liquid Fertilizers
  • When sending in a liquid sample, it is very important not to ship in a glass container. Instead choose a plastic bottle for liquid fertilizers. 
  • We need around 4-8 ounces of liquid fertilizer for most tests.
  • Please leave a little head space in your container so that the sample can expand if necessary, and so we can mix the sample properly.
  • Wrap electrical tape around the top of your sealed container. This helps ensure that the cap will not come loose during shipment.

 

  1. Submitting Dry Fertilizers
  • Place dry fertilizers in a “Ziploc” type baggie. We suggest that you double bag it to help contain sample if it leaks.
  • We need around 1 cup of dry fertilizer for analysis.

 

  1. Submitting Lime Samples
  • We need approximately 2 cups of limestone sample if sieve work is needed and 1 cup if it is not. If your sample is a wet sludgy type, we will need closer to 3-4 cups. Use the sampling container most appropriate for the material to be tested.

If you have any questions about submitting lime or fertilizer samples, please call Diane, fertilizer department manager, or one of our agronomists at 260-483-4759 and we will be happy to help.

Fall Management of Alfalfa

Fall is a critical time of year to manage alfalfa to ensure maximum productivity and stand longevity. Unlike annual crops such as corn and soybean, fall is when the alfalfa plant begins to store additional sugar, protein, and nutrient reserves in the crown and root system, which will provide protection from the cold winter weather and facilitate vigorous growth next spring. In a year such as this one, where hot and dry weather this summer was especially stressful to the plant, it is crucial to allow the alfalfa crop to prepare for the cold months ahead.


One of the most important management practices involves timely harvest. Final cuttings should be made early enough in the fall to allow the crop to regrow adequately and replenish necessary reserves before a killing frost, and should generally be completed by early to mid-September, depending on your location and local climate. More guidance on the exact timing can be obtained from state Extension publications or your local Extension agent. This is also a good time of year to assess the overall health and quality of an alfalfa crop, including evaluating stand density and root and crown health, allowing you to address any problems before they become serious.


Also critical for maintaining a successful alfalfa stand is managing the fertility of the crop. Fall is a good time of year to make fertilizer and lime applications. Low levels of nutrients, particularly potassium (K), can also lead to reduced stand health and vigor. In addition to the other essential functions of K in the plant, K plays an important role in the plants’ ability to resist subfreezing temperatures, and low levels of K in the plant can lead to increased winterkill if conditions are favorable. In addition, maintaining a proper pH with liming is critical for a number of reasons, including maximizing the availability of other nutrients and ensuring successful nitrogen fixation. Since lime requires adequate soil moisture and time in order to affect soil pH, making lime applications in the fall allows the liming material time to react and can have a greater effect on next year’s crop.


Careful management of your alfalfa crop this fall can mean a stronger, more vigorous crop next year. Therefore, taking some time to care for your alfalfa crop today can mean better results tomorrow and beyond.
