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.
You might think that when nitrogen fertilizer is in the ground, it's safe. New research suggests you need to think again. When shallow banding unprotected urea less than two inches deep, researchers found that nitrogen loss due to ammonia volatilization can be even greater than unprotected broadcast urea.
A study by Dr. Rick Engel from Montana State University proved that surface-applied urea still loses a significant amount of nitrogen due to ammonia volatilization in cold weather, even under freezing conditions. High ammonia volatilization loss under cold conditions was mainly related to high soil moisture and soil pH.
While fall applications of nitrogen can help take pressure off spring field work, allowing for more timely planting, these applications are still at risk of nitrogen loss. We’ve debunked two common myths concerning nitrogen loss in fall-applied nitrogen to help ensure growers are maximizing their nitrogen fertilizer inputs.
Soil is a nonrenewable resource that directly and indirectly produces about 95 percent of the world’s food* — so while defining soil health may not be easy, understanding its value is.
N-TEGRATION™ Technology from Koch Agronomic Services (KAS) seamlessly integrates an innovative technology platform with existing urea manufacturing processes to produce a homogeneous, 46% nitrogen, ready-to-use enhanced efficiency fertilizer.
Selecting what fertilizer best fits your operation can be a difficult process — this likely isn’t a surprise to you. With so many factors playing into the equation, how do you decide what details to consider to ensure your crops get the essential nutrients they need? This article discusses three key factors to think about as you explore your fertilizer options and how SUPERU® premium fertilizer from Koch Agronomic Services stacks up in each category.
Nitrogen management is essential to prevent nutrient loss, maximize yield potential and optimize economic return — it’s especially important when your nitrogen program includes a fall application.
While growers are familiar with the unpredictability of the weather, the varying impacts of weather systems in the fall and winter can mean leaving input investments to even more chance.

DCD or dicyandiamide is the active ingredient found in many fertilizers and additives marketed for their nitrification inhibition properties, including SUPERU fertilizer. SUPERU is a finished fertilizer with 8,500 ppm DCD that is backed by more than 25 years of research and hundreds of trials.
Packed with unsurpassed efficiency in every granule, SUPERU premium fertilizer has been scientifically formulated to protect a grower’s nitrogen investment against volatilization, leaching and denitrification. With both urease and nitrification inhibitors, SUPERU enhances nitrogen efficiency, boosts yield and minimizes potential nitrogen loss to nearby water sources.
In a study evaluating various enhanced efficiency fertilizers (EEFs) on effectiveness of reducing nitrogen loss from denitrification and leaching, SUPERU® premium fertilizer led the way.

We know that nitrogen is an important element. It makes up 78% of our atmosphere and is a key component in plant growth. But how do plants utilize this key nutrient? What role does nitrogen play as a crop nutrient? How do the three types of nitrogen loss differ?
To better understand why plants need nitrogen to grow, it’s important to know what the element does and why the nitrogen cycle is a necessary part of all living matter.
If the 2019 season taught us anything, it’s that things don’t always go according to plan. But that doesn’t mean looking ahead is a fruitless practice. With that in mind, have you started thinking about your 2020 nitrogen plan? A strategically planned anhydrous ammonia application can deliver significant agronomic and operational benefits. But how can you be confident your nutrient investment will still be available when crops need it?
There is resurgence in interest on topdressing nitrogen for a variety of reasons. First, the perception is that top-dressing nitrogen fertilizer during the growing season offers potential benefits in cost and efficiency. Second, recent weather patterns have forced many farmers to either skip or miss the opportunity for fertilizer application prior to or at seeding time. Finally, protein premiums for spring wheat can be enticing at times
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.
