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.

There are several misconceptions when it comes to UAN, including that it is not subject to nitrogen loss via volatilization, with many believing the water content found in UAN is enough to protect it from above-ground losses. We’re here to dispel this myth and help growers make the most of their UAN investment.

While soil CEC is a critical component for soil, there are common misconceptions when it comes to its relationship with nutrients. To understand the relationship between soil CEC and nutrients, we need to understand the chemistry behind the soil and the nutrients found or applied to the soil.
