Soil is a nonrenewable resource that directly and indirectly produces about 95 percent of the world’s food1 — so while defining soil health may not be easy, understanding its value is.

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.

The process of keeping nitrogen available to nourish crops is complicated. Learn how you can protect against nitrogen loss with Koch solutions.

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.
