Koch Agronomic Services’ (KAS) next-generation nitrogen stabilizer, ANVOL®, demonstrated extended protection against nitrogen loss due to volatilization in recent research. While untreated urea lost 32 percent of its available nitrogen, urea treated with ANVOL lost just 12 percent.
Nitrogen loss can be a serious problem impacting yield potential and return on investment. Depending on the soil type, nitrogen fertilizer is susceptible to losing more than 50% of its nitrogen through ammonia volatilization, denitrification and nitrate leaching.
The goal in crop production with nitrogen is to ensure as much of it as possible is available for plant uptake, where it can then be converted to grain throughout the growing season. While we know nitrogen is important to our crops, do we know what role it plays and how to ensure it’s available for optimal crop growth and production?
According to the National Weather Service Climate Prediction Center, growers across the U.S. may start noticing the impacts of El Niño as we progress into the fall and winter seasons.
Growers should soon be planning their winter top-dress applications. While crop progress and weather conditions vary, the 4Rs of fertilizer application pertain across the wheat belt.
Urea-Ammonium Nitrate, also known as UAN, is an excellent source of nitrogen for crops. However, farmers may dismiss the risk of nitrogen loss from UAN, incorrectly assuming that liquid forms of nitrogen are not subject to appreciable volatilization losses.
If it ain’t broke, don’t fix it. A cliché expression used by some to say there are things in life better left alone. For nearly 25 years, that phrase could accurately be applied to above ground urea and UAN nitrogen protection.
Record-setting rain during the 2018 fall limited or prevented fertilizer applications in many regions of the U.S. Add to that an abundance of late winter precipitation, below average temperatures and large snow melt have led to record-setting floods in parts of the Midwest and saturated fields in other parts of the U.S., making it difficult for growers to hit the ground running this spring.
With persistent wet weather patterns across the U.S. causing logistical strain and delay of many growers getting into their fields, some are already making the switch from anhydrous ammonia to other nitrogen sources. This means now is the time to discuss nitrogen source alternatives and nitrogen protection options with your growers.
Nitrogen volatilization can occur in all weather conditions, including both warm and cold temperatures. But no matter how or when fertilizer is applied, without a stabilizer, it’s vulnerable to loss.
UAN is a combination of urea, ammonium nitrate and water that forms to combine this liquid fertilizer.

氮肥流失可能成为影响产量潜力和投资回报的严重问题。根据土壤类型的不同, 氮肥很容易通过氨挥发、反硝化作用以及氮淋失而损失超过 50% 的氮。
For more than 25 years, AGROTAIN has been the dependable nitrogen stabilizer from Koch Agronomic Services (Koch) that has time and again helped growers optimize their yield potential. But what if there was something even better?
2019 was a record-breaking year in more ways than one – devastating floods plagued most of the Midwest, preventing many growers from planting spring crops on more than 19.4 million acres according to the USDA.
In a 2019 cotton study, urea treated with ANVOL® nitrogen stabilizer and SUPERU® premium fertilizer, applied at varying nitrogen rates, consistently outperformed untreated urea resulting in greater cotton lint yields.
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.
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.
Summer applications of nitrogen fertilizer on pastures can boost production, but there are risks of nitrogen loss.
Each year, new agronomic solutions are introduced for growers to consider using to help them better their operation. The best of those allow growers to use fewer resources, potentially saving them money in the long run and promoting a more sustainable future.
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.

The Field Notes podcast series from Koch Agronomic Services (Koch) will break down the science and technology behind agronomy to help growers do more with less. Crop science experts and others in the agriculture industry will discuss topics ranging from nitrogen loss and soil health to ways growers can increase operational efficiencies.
