# Grupa Azoty introduces sulphur-based fertilizer as it reinforces core business

Publication Date: 03.03.2026, 12:00

Polish chemicals group expands nitrogen portfolio with product aimed at improving nutrient stability.

Grupa Azoty has launched a new nitrogen–sulphur fertilizer, adding to its portfolio as it continues to position fertilizers as the central pillar of its business.

The fertilizer segment is expected to provide company’s operational stability and competitive scale in the European market, while supporting agricultural production in Poland and neighboring countries.

The new product, DuoS,![](https://www.fertilizerdaily.com/wp-content/uploads/2026/03/643316548_1494853889317308_5237888290534681657_n.jpg) combines nitrogen, sulphur and calcium in a single formulation. It is designed to address nutrient losses linked to leaching and the instability of certain nitrogen and sulphur forms.

The formulation contains two types of nitrogen—nitrate and ammonium—and two sulphur sources, ammonium sulphate and anhydrite. Calcium has been added to support crop resilience and yield quality.

The product’s sulphur-release profile is structured to ensure availability both in early growth stages and later in the season. The nitrogen-to-sulphur ratio has been adjusted to better reflect crop uptake patterns and reduce the risk of excessive stimulation during sensitive periods such as early spring and late autumn.

The launch is part of a broader plan to expand the group’s range of more specialized fertilizers in the current season.
