FOSFAN S.A. is currently one of the most dynamic multicomponent agricultural and horticultural fertilizers producer operating in the market. A new company brand, i.e. "Port Nad Odra", covering transshipment and warehousing services, has been effectively competing in the regional and national transshipment market.
The origins of the company date back to the 19th century, when the research on plant nourishment, carried out by Justus von Liebig, aroused the interest in chemical compounds that could help farmers increase their output. At the time agriculture needed fertilizers, while quickly developing industries were in need of more and more chemicals. Industrialist of Szczecin answered the market's call. It was here that several chemical plants were founded. One of them, set up in 1872 as a joint stock company, was Fabryk Chemischer Produkte UNION A.G.
The location of that new factory was ideal - it was erected on the bank of the Odra River, right next to a railway station. Today two Szczecin districts border here: Glinki and Krasnica (then: Glinke and Kratzwieck villages), that is why some sources quote that the company headquarters are in Glinki, other in Krasnice, still others the nearby Stolczyn (then: Stolzenhagen).
In the early years, fertilizers constituted UNION A.G. chief production profile, mostly superphosphate and basic slag phosphate (ground powder). As early as the 1880's the company greatly increased its output, first in 1887 from 18 thou. to 25 thou. tons, only to nearly triple it by 1890. The plant started playing an increasingly greater role in the economic life of the city, further compounded by successive takeovers of smaller chemical plants. In the 1890's UNION A.G. gained control over an old Metz factory, located in Grabowo district.
According to the inventory records of 1946, the factory was nothing more than ruins. The reconstruction of the destroyed UNION A.G. was already started in Szczecin in August 1946, but formal handover of the company property in the administration of State Superphosphate Factory,  especially set up for that purpose in Szczecin, took place only on 23 November 1946. In 1949 the factory name was changed into Phosphoric Industry Plant in Szczecin, and then into Pomeranian Phosphoric Industry Plant as a State Enterprise isolated in Szczecin.
Under a decision of the Minister of Heavy Industry of 18.08.1949, UNION Fabrik Chemischer Produkte A.G. company, until then managed by the state, was now taken over to become the state property.  1951 was the year of another change in the name, this time into Szczecin Phosphoric Fertilizers Plant in szczecin. It will turn out to be the name in the longest use in the post-war history of the company so far. The start of sulfuric acid manufacture in April 1949 was a beginning of the period of constant and stable operations of the factory. In 1955 work on building a granulation section commenced, and the following year its first line was already put in operation - 31 862 tons of fertilizer was manufactured, while the second production line started operating in 1957. each production line constituted a separate, independent technological run.
Next to the basic product, that is granular superphosphate, the factory also produced microelements-enriched fertilizers. 1973 is the starting point of a long tradition of horticultural fertilizers, currently the best ones in the market. It was then that the installation for the production of horticultural fertilizer was started, a well-known FRUCTURS brand. A technical factory reconstruction, carried out over the period from 1974 to 1977, involving a complete change of fertilizer manufacture technology, turned out to be a turning point in the company's post-war history and a crucial moment in its development. The economic system transformations of 1989-1990 constituted a serious challenge for the company. A falling demand for fertilizers, liquidation of the previous central distribution system and the need to create its own commercial network posed new difficulties. In the face of this new reality and new market demands, a series of adaptation actions were undertaken, which enabled the company to survive and maintain its basic employment level. Uncertain management conditions forced the company to seek new sources of revenue. Offering services based on its own port quays and infrastructure turned out to one way of revenue diversification. In 2005 the plant started manufacturing a wide range of FRUCTUS horticultural fertilizers, which can be applied on leaves or into the soil. 1998 - 2005 brought changes in the company's legal position and its ownership. At present FOSFAN is a joint stock company with a private, fully Polish capital.
