Liquid urea fertilizer solutions and fluid fertilizers are popular in many areas because they’re safe to handle, convenient to mix with other nutrients and chemicals, and are easily applied. Liquid Urea containing 44 percent nitrogen (N) is the most popular fluid N fertilizer.
Solutions of Liquid Urea are extremely versatile as a source of plant nutrition. Its chemical properties, make Liquid Urea compatible with many other nutrients and agricultural chemicals, so its frequently mixed with solutions containing phosphorus, potassium and other essential plant nutrients. Fluid fertilizers can be blended to precisely meet the specific needs of a soil or crop.
Liquid Urea solutions are commonly injected into the soil beneath the surface, sprayed onto the soil surface, dribbled as a band onto the surface, added to irrigation water, or sprayed onto plant leaves as a source of foliar nutrition.

What is nitrogen and why is it important?

Nitrogen plays the most important role in the world of plants. It is an essential nutrient to create plant mass and, therefore, appears in many fertilizers.

Management practices

When Liquid Urea is first applied to soil, the urea and the NO₃- molecules will move freely with water in the soil. The NH₄+ will be retained in the soil where it first contacts cation exchange sites on clay or organic matter. Within two to 10 days, most of the urea will be converted to NH₄+ and no longer be mobile. The originally added NH₄+ plus the NH₄+ coming from urea will eventually be converted to NO₃- by soil microorganisms.
