The Windeby site is an arable farm characterised by the cultivation of seed potatoes at the highest multiplication levels and close cooperation with the breeding station. It was established as an important foundation after World War II in 1948. In addition, two biogas facilities are operated in Windeby, which generate enough energy to supply around 2,000 households with electricity.

We are focussing on the cultivation of many types of crops and thus on a broad crop rotation. The fertiliser produced as a by-product in the biogas facility is reused on our land as part of the circular economy. With these measures, we ensure a healthy soil structure and ideal starting conditions for the cultivation of healthy seed potatoes as well as food and animal feed.


Potato farming in Gransebieth has a long tradition. Even before the site became part of the Solana Group in 1991, potatoes were grown in Gransebieth. The soil conditions and the local climate provide optimal growing conditions for seed potatoes. In addition to the external conditions, we also ensure production through our sprinkling facilities.

Gransebieth is one of three locations for potato performance testing. Every current and future Solana potato variety has proven its suitability and performance in Gransebieth.


The Ranzin site is located in the centre of the healthy area for seed potato production, an EU protection zone. SaKa Pflanzenzucht (plant breeding) operates another breeding station in the immediate neighbourhood and produces, among others, seed potatoes of the very highest quality. This seed potatoes are propagated by our farm in Ranzin in the further stages. The high-quality seed potatoes are produced on site in an almost closed system.

The basis for the production of healthy seed potatoes is a wide and varied crop rotation. We participate in the EU's crop rotation programme with more than eight different types of crop. In addition to potatoes, we also breed, test, and multiply grain varieties on our land.

Our potato storage centre in Züssow (Kartoffellagerhaus: KLH Züssow) is also part of the Ranzin site. In Züssow, more than 15,000 tonnes of seed potatoes are sorted, prepared, and packaged for national and international shipping.


In Bömitz, too, the potato traditionally has a solid place in the crop rotation cycle. At our newest site, which was taken over in 2021, we produce potatoes as a basis for food and starch production.

In a highly diversified crop rotation cycle, we also produce peas alongside the major market crops, which are an excellent addition to vegetarian and vegan diets thanks to their high protein content.


Our farm in Stolpe is located directly by the Peene River. The Southern Peene Canal enables us to use the surface water to sprinkle our seed potatoes, which are cultivated in Stolpe.

At all of our locations, we ensure that our land is green all year round by growing catch crops. The cultivation of catch crops and the controlled use of organic fertilisers are particularly important in Stolpe due to the poor soil quality. Thanks to long-term systematic improvement of the soil structure, the ecological and economic value of the land can be steadily increased.

Location Stöffin

In the centre of the county of Ostprignitz-Ruppin, we cultivate arable land and green areas at the Stöffin site. Potatoes are also grown in Stöffin for the production of starch. The potatoes are delivered to the nearby starch factory in Kyritz.

The climatic conditions and the sometimes very poor soil quality at the site place high demands on a healthy soil structure, which we meet in Stöffin by consistently cultivating catch crops and using mostly organic fertiliser.

Some areas are not suitable for the production of food and animal feed due to their quality. These areas are cultivated as ecological priority areas. The aim of cultivation is to preserve and promote a high level of biodiversity.
