YaraVera AMIDAS Urea is hard, homogeneous and provides no segregation.

AMIDAS is harder than many other fertilizers.

Storing and handling of fertilizers can result in a breakdown of particles due to crushing. Harder fertilizers, such as Amidas, have fewer broken granules, produce less dust and provide more uniform spreading.

In a demonstration, non-Yara urea crushed at just 4.5 kilograms of pressure. Amidas is much stronger, withstanding 7 kilograms of pressure before crushing. The result is a product that maintains a more uniform particle size all the way through to spreading on the crop. Fertilizer granules with a crushing strength of <3 should not even be used with spinner speeds >700 rpm.
