YaraVera AMIDAS

YaraVera AMIDAS (40% N + 14% SO3) is a sulphur-enriched and urea-based granular fertiliser, which delivers higher yield results than urea alone. It’s designed for use on oilseed rape, arable crops and grassland.

YaraVera AMIDAS is formulated to supply nitrogen and sulphur to a wide range of arable crops and grassland. Its 7:1 nitrogen to sulphur ratio is ideal for oilseed rape and other brassica crops. By combining urea with sulphur in the sulphate form, sulphur uptake by plant roots is increased.

Immediate and long-term growth response

With 5% ammonium nitrogen, as well as 35% ureic nitrogen, your crop gets the best of both worlds:

Immediate growth response to the ammonium nitrogen
Long-term nitrogen availability with ureic nitrogen to sustain growth throughout the season.

Optimised sulphate availability

As industries have reduced their air pollution, we have seen a knock-on impact on sulphur levels in our soil. Sulphur deficiency is now widespread across UK soils.

YaraVera AMIDAS delivers plant-available sulphate to achieve improved crop quality and increased yields.

Sulphur deficiency in plants will cause stunted growth and the leaf will develop a pale green colour. Sulphur is essential for a plant’s basic functions - it is needed for plant amino acids, the building blocks of protein.

Decreased volatilisation

By adding sulphur into AMIDAS, you’ll see more efficient nitrogen uptake. Urea on its own will increase the pH of your soil, resulting in a significant loss of nitrogen after application. Sulphur counteracts this by reducing soil pH, therefore cutting down on nitrogen losses long enough for your crops to see the benefit.

The benefits of using YaraVera AMIDAS

Sulphur in sulphate form results in increased root uptake
As a true granular compound, AMIDAS guarantees an even spread with the same nutrient content in every granule
The ammonium/urea blend reduces volatilisation and increases use efficiency
Non-hazardous for storage.
