Eating the right food keeps you healthy, gives you energy and helps you grow. Nourishing soils with the right plant food does the same thing for crops and forages. Plants need a balanced diet as much as you do, and the right nutrition leads to healthier soils, better yields and higher-performing animals. That’s not only good for the farmers, but it’s also good for the land and a rapidly growing world population.

The 2019 growing season was certainly memorable, but it may be one that many would like to forget. Despite the stress it put on both growers and input suppliers, I feel there are many lessons to be learned in such an extreme year.
Last year, MFA used a new nitrogen-modeling tool called Nutri-Track N. It was certainly an interesting year to roll out this new technology. While we had been experimenting and demonstrating Nutri-Track N since 2016, last year was the first time we had such extreme potential for nitrogen loss. Previously, we had seen this recommendation tool help improve nitrogen use efficiency to 0.8 pound of nitrogen for every bushel of corn yield in many areas. That wasn’t possible in 2019, with excess rainfall pushing nitrogen below the root zone of the corn crop before it could be utilized.
During the past growing season, it took significantly more nitrogen to raise a bushel of corn than it did in previous years. For example, in one field where a check strip was left with no top-dress application, there was a 40-bushel per acre yield penalty. Nutri-Track N let us see the trend developing and respond appropriately, which is exactly what we hoped would happen. This recommendation system allows us to tailor nitrogen applications to the current weather pattern.
What makes the Nutri-Track N system different? It is based on years of university research that explains and models nitrogen’s life cycle in a field. It collects rainfall, temperature, soil data and all the agronomic field practices we can provide, and then it estimates the amount of N that is available when the crop needs it most and models the need moving forward. Not only does it track what nitrogen is applied but also estimates what has been mineralized from soil organic matter (OM). The more information we can feed to the program, the better the recommendation.
The best recs are achieved with the combination of grid sampling to provide OM levels and historic yield data to give us variable yield potential. By evaluating all these factors, Nutri-Track N shows the current status of the field and where it is expected to be at the end of the season—assuming typical weather patterns. The model is constantly improving by updating every night with new adjustments based on the previous day’s actual recorded weather.......
In practice last year, this technology worked as we had hoped. In mid-May, the MFA Precision Agronomy team started to send out alerts to our staff, warning that fields with unprotected fall nitrogen applications were at extreme risk of running short of this essential plant nutrient. By late May, we began to see more fields—even some that had received spring applications— that would benefit from topping off the nitrogen mid-season. The windows were tight to get that N applied, but it paid dividends when the combines rolled this past fall. In my estimation, nitrogen management was second only to stand establishment in terms of importance to overall yields in 2019.
So, what did we learn from last year?
While we’ve always understood that using split applications with a planned top-dress application could improve nitrogen use efficiency, this past season, the system paid big yield dividends as well.
The later we can wait to make our overall total nitrogen investment, the better off we are. The more information we have about our growing season, the better N rate decisions we can make.
Protecting your nitrogen with proven stabilizers pays. Anything we can do to maintain nitrogen in the ammonium form in the soil for a longer period is critical, not only to protect your investment but also keeping that nitrate out of surface waters.
There is no single right rate or application method for all of our nitrogen needs. It is a system with many variables. However, with the right tools we can continue to improve efficiency and yields as we gain experience and knowledge.
I’m excited to see the results from those producers who used Nutri-Track N last year. While no two years are the same, I feel confident that we are managing nitrogen better today and will continue to improve into the future.

Turbocharged engines are popular in many vehicles today because of the improved performance they provide. The turbocharger boosts horsepower, or output, while increasing fuel efficiency. It works by capturing unused energy from the engine exhaust to power a turbine. This, in turn, powers a compressor, which forces air into the intake of the vehicle, allowing a greater percentage of fuel to burn with each stroke of the engine. The result is greater output with less fuel by introducing a little more air.
The turbocharger is a really good example of synergy, where the output seems to outpace the cost of the inputs. Synergies in crop inputs are often misunderstood, oversold or dismissed, but some combinations do work and pay big dividends. One such example of successful synergy is the use of foliar slow-release nitrogen (SRN) in conjunction with foliar-applied fungicides.Slow-release nitrogen products......
...are often touted as a more efficient method of N delivery in which low-use rates can replace multiple pounds of soil-applied N to reach a similar yield. In my opinion, this is the worst expectation to have from an SRN. It can’t replace sound base nitrogen fertility—just like a turbo would be useless if there were no oxygen to pump into the system.
Where slow-release nitrogen can really shine is when used with strobilurin fungicides. Beyond disease control, fungicide benefits include stay-green, stress tolerance and standability. What we don’t often discuss is where those advantages come from. With stress tolerance, increased photosynthesis and grain fill, the biggest impact comes from increased efficiency in nitrogen metabolism. The trick is having enough available N to “boost” that process.
Like the turbocharger increases the amount of oxygen for an engine to more efficiently burn fuel, SRNs provide enough nitrogen to allow fungicides to reduce stress and promote plant growth, resulting in more gain at higher N efficiency.
We’ve seen positive results of an SRN-fungicide combination in trials like the one conducted by Dr. Kelly Nelson with the University of Missouri’s Greenley Research Station. He added 1 gallon of SRN to a fungicide application of Headline AMP at tassel to corn. While Headline alone added 14.5 bushels per acre, adding SRN led to an increase of more than 25 bushels per acre. Thanks to the synergy created by the combined application, the amount of N is far less than required to add 9 bushels in traditional thinking.
Slow-release nitrogen products have been available for quite some time, and we have recommended them as a way to increase the efficiency of a fungicide application. Recently, MFA took it a step further by introducing a new proprietary product, Gold Advantage Trend-B, which is an SRN with boron added. Boron is an essential nutrient needed during the crop’s reproductive stages for grain development.
The issue with boron, unlike many plant nutrients, is that it is very mobile in the soil but not in the plant. This means that even if you do fertilize with boron up front, what is not taken up early is likely lost, and what is taken up early does not move in the plant to areas it is most needed. A plant with a fungicide plus SRN and deficient boron is like a turbo’s boost being held back by an engine with poor timing. Trend-B not only adds the small amount of available N necessary to help a fungicide “turbocharge” plant performance, but it also helps maintain optimal boron nutrition, which is often needed late in the season.\Proper timing is critical to get the most out of these applications. Talk with your Crop-Trak consultant or other experts at your MFA location today about the opportunity to improve your crop’s health and increase yields by combining fungicides with SRN foliar nutrition.

The world of weed control in forage systems has seen some growth in the past decades. Where growers in row-crop systems have been patiently awaiting new products to hit the marketplace, forage producers have been blessed with new options. Along with the ability to consistently remove broadleaf weeds from pasture and hay fields comes the ability to apply those herbicides in cost-effective ways, such as dry fertilizer impregnation (DFI).
With DFI, a pasture weed-control product is coated onto dry fertilizer being applied to forage fields. The real advantage of this system is the herbicide’s residual control, which suppress especially small or yet unemerged weeds. By allowing fertility and weed control to be applied simultaneously, DFI can be a tremendous cost and time savings during a busy time of year for many of MFA’s diversified growers.............
There are many advantages to this approach, but DFI still should be treated like any other weed-control system in forage production. Expectations should be based on when the product is applied and how much coverage is attained. The best control will still be achieved with good coverage in a broadcast spray scenario. Control of emerged weeds using DFI is expected to achieve 60-70% of that of a well-timed broadcast application. The good news is that residual control of unemerged weeds is excellent.
Here are a few considerations when using weed control with DFI:
Coverage is king. MFA recommends at least 250 pounds per acre of dry product applied with herbicide. The more product applied, the more even distribution of the weed control active ingredient placement. Double spreading is also recommended to ensure good, even coverage.
Adjust timing. Optimal time for controlling summer annual weeds in pasture is later in the season than most grass fertilizer applications. On pasture, May is an ideal time to get the residual control in products such as GrazonNext HL or the newly released DuraCor for summer annuals. For good control on hay fields, timing should be closer to early April. These later-season applications generally influence production of more leafy matter in the grass stand, resulting in higher-quality forage. Weed identification is still critical when planning for application timing. Contact your local MFA for assistance with both weed ID and optimal timing for application.
When looking at fertilizer applications later in the season, think about the growth curves of cool-season grasses such as fescue. Nitrogen uptake is winding down by May or June, so an application would be a great chance to catch up on some P and K based on needs identified in soil samples.
Advance the system. With land costs continuing to be high, maximizing the acres you currently operate remains critical to the economics of profitable forage production. Weed control is a good first step. Continue to move your forage growth forward by addressing fertility based on soil sample data, leaving residual forages to allow for faster regrowth, and diversifying your grass species to take advantage of hot, dry summers.
MFA is excited to be offering dry fertilizer impregnation at many of our locations this year. We think it’s an efficient way to manage weeds on acres that may have not had such control in the past. If you’re interested in pasture weed control this season, contact me or your local MFA for the product and system that will work best for you.
