YaraVera premium fertilizers offer all the versatility of urea based products, with added agronomic benefits. With a nitrogen concentration of 40% and over, these highly efficient sources of urea ensure strong, sustained growth over a prolonged period through effective nutrient release. They can be applied to the soil as solid granules, in solution or, to certain crops, as a foliar spray.

The superior quality of YaraVera products helps to reduce handling, storage and transportation costs, and supports optimum-efficiency plant growth, leading to some of the highest yields possible and providing better return on investment for growers.

YaraVera products often contain added nutrients. If you are looking for an alternative to ammonium sulphate blends, YaraVera AMIDAS is the right choice for you.

YaraVera AMIDAS a highly water soluble homogeneous granulated product that offers an ideal N:S ratio of 7.3:1. The greater hardness of the granules maintains particle integrity, reduces dust and provides more uniform spreading.

YaraVera AMIDAS' unique homogeneous composition will not segregate

ammonium sulphate segregation

YaraVera 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.

YaraVera 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. The ammonium nitrogen and sulphate sulphur are immediately available to plants. AMIDAS's N:S ratio of 7.3:1 is ideal for most crops.

Optimal plant uptake of both N and S

YaraVera AMIDAS is a unique granular homogeneous fertilizer that contains nitrogen and sulphate sulphur readily available to the crops in an ideal N:S ratio of 7.3:1 - optimal for amino acid and protein synthesis. 
The presence of ammonium sulphate in the same granule as urea promotes optimal plant uptake of both N and S.
N and S are essential for plant structural and functional protein development. Applying these nutrients together with the AMIDAS homogeneous product helps assure top yields by supplying N and S in the forms the plant needs.

YaraVera AMIDAS produces an even distribution pattern

Each granule of YaraVera AMIDAS is a homogeneous chemical mixture of N and S in the form of urea and ammonium sulphate. It cannot segregate. Fertilizer blends can segregate during handling and storage in the bag, pile, in the spreader hopper and during spreading. Once segregated, an uneven application of nutrients results.

Another consideration is that the spreading width of small, light particles is less than that of a larger, heavier particles in a blended mixture. The result is uneven nutrient application causing striped fields and reduced yields. Also, nitrogen and sulphur in the same granule enhances root uptake compared to blends, resulting in balanced nutrition for optimal plant growth.

YaraVera 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 YaraVera 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.
