Keeping You On Your Toes

As you plan for the next growing season, fluctuating commodity prices may have you looking at your expenses. In order to manage tighter margins, you could even be tempted to cut input costs but it may end up hurting your bottom line.

Studying the true costs of ag inputs, you will find that cutting stabilizers from your nitrogen management program may leave your crops – and your profitability – at risk. 

Looking at it in a Different Way

Two Nebraska agronomists compared some of the cost-cutting questions they’ve fielded from the growers they advise.

As a field sales agronomist with Country Partners Cooperative, Donnell DeLosh says he counsels growers to consider stabilizers as more like insurance for their nitrogen.

“They're always going to be asking you ‘well, how much more yield am I going to get if I use this product or that product?’,” says DeLosh. He asks them to think about it the other way around.

“It's not about how much more you're going to get,” he says. “But how much can you afford to lose. We want to keep that nitrogen right there where your corn can get to it and use it.”
Another field sales agronomist agrees. Thad Russell with Central Valley Ag says his growers are looking at ways to cut costs. But Russell says that growers “never know what Mother Nature is going to do” so stabilizers “are things that we've just got to keep in the plan.”


Fall Applications

In many areas, the practice of utilizing stabilized nitrogen in fall can help keep applied nitrogen where it belongs for a longer period of time. Both agronomists are using that strategy with their growers.
DeLosh says that application best practices have changed for the better over the years. “The days of going out there with 150 pounds of nitrogen in one shot is not the norm anymore. Spreading that nitrogen out, and then stabilizing – that, I think, has made a huge contribution.”

Stabilizing Solutions

With farms getting larger and the work force in rural areas shrinking, agronomists know that they need to find solutions that are cost effective and easier to use. Both DeLosh and Russell agree – they’re happy with the products they’re using from Koch Agronomic Services (Koch).

Protecting a nitrogen investment from loss via denitrification, volatilization and leaching can be one of the key components to an operation’s success. 

For instance, CENTURO® nitrogen stabilizer boosts nitrogen use efficiency by up to 25 precent1. By keeping applied nitrogen in the ammonium form three times longer than without an inhibitor2, CENTURO allows more nitrogen to remain available for plant uptake. 

  • The nitrogen protection of CENTURO was highlighted in the higher yields seen in a three-year study in Nebraska, Illinois and Missouri. It showed that fall-applied CENTURO-treated ammonia increased corn yield by an average of 6 bu/acre compared to untreated fall-applied ammonia. Spring-applied CENTURO treated ammonia also increased corn yield by an average of 6 bu/acre compared to untreated spring-applied ammonia.

If harsh weather conditions have hit your operation’s bottom line with all three types of nitrogen loss, then SUPERU® enhanced efficiency fertilizer is a good solution. SUPERU is the highest concentration of nitrogen available in a dual-stabilized urea-based granule that provides protection from all three forms of loss.

  • If you could improve yield by 26 percent over untreated urea, wouldn’t you do it? That’s what a study in Texas found with wheat at 63 lb. N/acre of SUPERU at-planting. In addition to that level of gain, the research also associated SUPERU with greater grain nitrogen uptake efficiency and protein content3.

When a significant amount of the nitrogen you’ve invested in is lost and your crops suffer, ANVOL® nitrogen stabilizer is the solution for you. Keeping urea-based nitrogen where it can benefit the plant most, ANVOL delivers the longest-lasting urease inhibitor protection over a wider range of soil conditions. The stabilizer features the patented active ingredient Duromide along with NBPT, the same proven active ingredient found in AGROTAIN®. Those dual active ingredients increase your window of inhibition by up to 27 percent compared to NBPT alone. 

  • Studied on different crops, ANVOL has been shown to protect your nitrogen investment. Research showed ANVOL-treated urea produced a 31 bu/acre average corn yield advantage compared to untreated urea in a 2016-2018 study4. In a study from Louisiana State University, untreated urea lost 32 percent of its available nitrogen, while urea treated with ANVOL lost just 12 percent5
