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

Amidas Homogeneous

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.

Amidas is hard
Amidas Distribution header
YaraVera Amidas is unique in its production process. Molten urea and ammonium sulphate are combined during manufacturing resulting in a homogeneous granule. The ammonium nitrogen and sulphate sulphur are immediately available to plants. Amidas has an ideal N:S ratio of 7.3:1, which is ideal for most crops.


Properties of YaraVera® Amidas

Amidas has 40% nitrogen and 5.5% sulphur in the same granule. It’s totally water soluble and very uniform in granule size. It is a truly homogeneous product that ensures uniformity of application.

Figure 1: Amidas homogeneous composition of urea and ammonium sulphate will not segregate. The physical blend of urea and ammonium sulphate does. Note the ammonium sulphate (brown) concentration in the 1.4mm to 2.8mm size fractions.
