Agriculture keeps you on your toes — from changes in the economy, challenging weather conditions, to any of the other many variables you face — you’ve learned to be flexible. But if 2020 has taught us anything, it’s that we should be prepared for the unexpected.

Using a nitrogen stabilizer is one way you can help to insure your nitrogen investment and protect yourself from whatever this spring may have in store for you.

“Talking with your retailer now is a good idea,” says Jared Miller, master agronomy advisor for MKC. “It gives you time to look at what worked, what didn’t, and what your options are for the next growing season.”

Putting a plan in place and then knowing what to do if conditions change should give you peace of mind that you’re prepared for what may come your way.

Tim Laatsch, a farmer for more than 20 years in southern Illinois, is the director of North America agronomy for Koch Agronomic Services (Koch). He begins by following the best practices of 4R Nutrient Stewardship on his operation and supports having nitrogen management conversations in advance.

“Each grower needs to think through their options for managing nitrogen in order to reach their optimal yields,” says Laatsch. “Knowing that you are doing all you can to prepare for whatever spring will bring and not having to rush into a decision should put your mind at ease.”

Laatsch says he knows there are growers who unfortunately aren’t protecting the nitrogen they’re putting down in either spring or fall.

“Depending on the source, nitrogen is vulnerable to losses immediately following application or shortly thereafter,” he says. “If spring weather favors loss, nitrogen stabilizers will protect a grower’s nitrogen investment — preventing losses of valuable inputs to the water and the air, while avoiding added costs for rescue applications and sizable opportunity cost of lost yield.”

Spring Nitrogen Protection

There are many nitrogen loss myths — from false thinking that cold weather prevents loss of fall-applied nitrogen, to spring-applied nitrogen being safe from loss since it’s being applied closer to planting. Nothing could be further from the truth. Your nitrogen needs protected.

“The weather in spring can be unpredictable,” says Ed August, operations manager for Meherrin Ag. “A nitrogen stabilizer in general is pretty necessary. And at the end of the day, it’s the right thing to do.”

According to August, the vast majority of his growers are protecting their nitrogen with a stabilizer. Roughly 95 percent of them are using ANVOL® nitrogen stabilizer to keep their investment safe.  

ANVOL provides the longest-lasting protection against above-ground nitrogen loss — ideal for your spring applications.

Like its predecessor AGROTAIN®, ANVOL minimizes ammonia volatilization but has proven to extend the window of protection even longer. Dual active ingredients make the difference. NBPT, the same active ingredient found in AGROTAIN, blocks the hydrolysis of urea as soon as it’s applied. Then Duromide, Koch’s patented molecule, kicks in to keep that protection going longer than NPBT alone. That gives your fertilizer even more time before it has to be incorporated, helping to maximize nitrogen availability in your fields and providing a higher return on investment. 

ANVOL Yields

In a 2019 Michigan study1, UAN treated with ANVOL yielded 27 more bushels per acre of corn than untreated UAN. This yield increase was due to Duromide, which increases the window of inhibition by up to 27 percent compared to NBPT alone.


August added that there are several operational benefits to using ANVOL due to its higher active-ingredient concentration which enables a lower application rate. Benefits include fewer delays from spinner blade buildup compared to other products where you use twice as much product as ANVOL.

According to August, his team and the growers they work with are both very happy using ANVOL.

“Almost every ton that left my facility was treated with ANVOL to try to keep that nitrogen available for the plant as long as possible,” he says. “Our growers saw positive results. We cut the best corn crop we have ever grown.”

Nitrogen is one of the most critical nutrients for a corn crop and plays a large role in plant growth, development and yield potential. Depending on several environmental factors, nitrogen can be lost to from the rooting zone of the crop which can lead to a nitrogen deficiency.

Dealing with unknowns is nothing new in the world of agriculture. Rainfall levels, soil conditions, unforeseen maintenance costs — the list goes on and on. Local, national and international events are also capable of throwing a wrench in even the most well-run operation. The best growers don’t just understand this fact, they accept it and adapt their strategies to deal with whatever comes their way.
