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.
Applying livestock manure to crops is a cost-efficient way to fertilize. Unfortunately, when manure remains untreated, nitrogen content can be susceptible to loss through volatilization, leaching and denitrification. And when nitrogen isn’t available for crops, yield can be impacted.
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.
