Growing onions in Pomerania: why it is a rarity and what the numbers say

Onions are a rarity in Pomerania: Statistics Poland puts them at around 531 ha. We explain why nearly half of that area is our own fields in Żuławy.

Polish onions grow above all in the centre of the country, and Pomerania is a footnote in those statistics. According to Statistics Poland (GUS) data on field-grown onions, the whole Pomeranian Voivodeship grows around 531 hectares of them, of which nearly half, around 250 hectares, are our fields in Żuławy. In this post we show what the numbers say about onions in the region and why this rarity works in buyers' favour.

Where Polish onions really grow

The national onion map has looked similar for years. According to data from Poland's Agency for Restructuring and Modernisation of Agriculture (ARiMR), in 2025 onions were grown in Poland on around 22.3 thousand hectares, and the clear leader is the Kuyavian-Pomeranian Voivodeship with over 9.5 thousand hectares. Next come Greater Poland and central Poland. That is where the tradition, the service infrastructure and most of the large plantations sit.

Pomerania barely exists in this ranking. Around 531 hectares of field-grown onions in the whole voivodeship is less than 3 percent of the national area. In practice it means that in our area almost nobody grows onions on a commercial scale, and we do it on around 250 hectares, nearly half of the entire onion area in the voivodeship.

For the record: the area figures come from public statistics (GUS, ARiMR) and change from year to year. The scale of the disproportion is constant, though: onions in Pomerania are a niche, and Żuławy is the exception within that niche.

The numbers: the region versus our farm

The most interesting thing in the GUS data is not the 531 hectares itself, but the yields. The average yield of field-grown onions in the Pomeranian Voivodeship is, according to those statistics, 276 decitonnes per hectare, just under 28 tonnes. We harvest around 60 tonnes of onions per hectare, more than twice the regional average.

This difference in yield does not come from one thing. It is the sum of soil, varieties, irrigation, precision farming and the fact that onions are our main specialisation, not an add-on to other crops.

Why there are almost no onions in Pomerania

Onions are a demanding crop: they need good soil, equipment, knowledge and facilities for drying and storage. Where a lot of them are grown, a single farm draws on its neighbours' experience, local services and the machinery market. In Pomerania that ecosystem never existed, so the entry barrier is everything at once: from agronomy to a storage facility.

We got into onions more than a decade ago, starting from 2.5 hectares, mainly to widen our crop rotation and not base the farm solely on cereals. Over time it turned out that Żuławy conditions give onions more than anyone assumed, and the area grew to today's roughly 250 hectares. We describe the whole journey in our post on growing onions in Żuławy.

Żuławy is the exception, because the alluvial soils make the difference

The fact that onions are practically absent from Pomerania does not mean the conditions for them are missing. It is exactly the opposite: the Żuławy alluvial soils are river-deposited soils with a high humus content, comparable in their parameters to the Dutch polders on which Europe's onion powerhouse grew. The difference is that in the Netherlands those soils have been sown with onions for decades, while in Żuławy cereals and oilseed rape dominated for years.

We write more about that comparison in our post on Polish versus Dutch onions. The short version is simple: we play on similar soil, with the same variety genetics and comparable technology, just on the cheaper side of the border.

What the region's rarity means for a buyer

For a buyer, our position in Pomerania translates into concrete benefits. First, logistics: we are near the Tricity, close to the ports, the ring road and the markets of northern Poland, so the onions do not have to travel halfway across the country. Second, scale in one place: around 250 hectares of onions and a 13 000 tonne storage facility let you contract large, repeatable volumes from a single supplier instead of gathering produce from many small ones. Third, quality: we grow according to Integrated Plant Production, using technology with no pesticide residues, with GlobalG.A.P. and GRASP certificates.

Frequently asked questions

According to GUS data on field-grown onions, around 531 hectares in the whole Pomeranian Voivodeship, less than 3 percent of the national area. Nearly half of that, around 250 hectares, are our fields in Żuławy.

The leader is the Kuyavian-Pomeranian Voivodeship with over 9.5 thousand hectares according to 2025 ARiMR data. Greater Poland and central Poland also have large areas. The whole national area is around 22.3 thousand hectares.

Quality is decided by soil, variety and technology, not by the map itself. The Żuławy alluvial soils are among the best soils in Poland and comparable to the Dutch polders, which is why our onions reach yields of around 60 t/ha with full quality control of every batch.

We got into onions to widen our crop rotation, and we hit on soils that serve them brilliantly. Having no onion-growing neighbours meant a higher entry barrier, but today it gives us the unique position of the only grower of this scale in the region.
