Fertilizer urea

Quick facts

The agricultural industry widely uses urea, a white crystalline solid containing 46 percent nitrogen as an animal feed additive and fertilizer. Here, we’ll focus on its role as a nitrogen fertilizer.

In the past decade, urea has surpassed and nearly replaced ammonium nitrate as a fertilizer. This has brought up new questions about urea and how to use it.

Basics of fertilizer urea


Applying and storing urea


Urea do’s and don’ts

  • Store separately from ammonium nitrate.
  • Don’t use small, fast-moving augers to move the urea.
  • Don’t exceed a spreading width of 50 feet when urea is applied.
  • Don’t place urea in direct contact with corn seed.
  • Keep rates of nitrogen applied together with small grain in drill to 10 pounds on dry soils and 20 pounds when soil is moist.
  • Apply urea on sod crops when atmosphere temperature is below 60 degrees Fahrenheit.
  • When broadcasting urea on soils of high pH (above 7.5), incorporate the material into the soil as soon as possible.
