Reduced nitrogen losses through volatilization with coated urea

Nitrogen losses can decrease fertilizer efficiency dramatically. There are various pathways nitrogen can be lost, one of the main ones being volatilization. Urea and ammonia nitrogen are especially easily volatilized in ammonia (NH3) gas form, which means a substantial percentage of nitrogen fertilizer can be lost that way.

Governmental bodies have set clear measures to reduce the risk of losing nitrogen to the atmosphere. To comply with regulations, growers can look to incorporating fertilizer directly into the soil after application or using enhanced efficiency fertilizers, such as nitrogen inhibitors or coated, controlled release fertilizers.

Reduce nitrogen losses by at least 40%

Controlled release urea (like ICL’s Agrocote Max) protects against nitrogen volatilization thanks to its coating. Most losses through volatilization happen directly after a fertilizer is applied to the field, but the coating of a controlled release fertilizer ensures that ammonia gas losses are minimized. Research has proven that controlled release urea can reduce nitrogen losses through volatilization by at least 40%.

To show you how controlled release urea can reduce volatilization, we set up a simple experiment. Watch the video to find out more:
