Fertilizer Guide – YaraVera Amidas – Nitrogen

The composition of YaraVera AMIDAS does not favor the ammoniacal phase (NH3) which is toxic for small roots in development, as urea does. In other words, unlike urea, with YaraVera AMIDAS 13% of the nitrogen released is in ammonium form which is available immediately.

A stronger granule, therefore, less dust and greater distribution

Using a hardness meter, YaraVera AMIDAS 40-0-0 5.5(S) has demonstrated to be stronger (average: 9.20 kg/granule) than granular urea 46-0-0 (average: 5.92 kg/ granule) and ammonium sulfate 21-0-0 24(S) (average: 1.32 kg/granule). In addition to the granule hardness, YaraVera AMIDAS offers superior handling due to particle uniformity and its virtually dust-free consistency.

A less volatile granule, therefore, fewer losses

YaraVera AMIDAS is unique because of its production process. Urea liquor and ammonium sulfate are combined during the manufacturing process to create a homogeneous granule. It is a truly homogeneous product that ensures uniform application. The ammonium nitrogen and sulfate sulfur are immediately available to plants. YaraVera AMIDAS’s N:S ratio of 7.3:1 is ideal for most crops.

YaraVera AMIDAS homogeneous composition of urea and ammonium sulfate will not segregate. The physical blend of urea and ammonium sulfate does. Note the ammonium sulfate (brown) concentration in the 1.4 mm to 2.8 mm size fractions in classic blends.
