Onions are the gem of our farm. We started with 2.5 hectares; today we grow around 150, with yields reaching about 60 tonnes per hectare, well above the national average.

Why Żuławy

Żuławy silt, soil made for vegetables

Żuławy is a land of fertile silt: heavy, humus-rich soils carried by water, full of nutrients and good at holding moisture. This ground cannot be copied, and vegetables repay it with yield and quality. Onions thrive here because they get even, steady conditions all season long.

How we grow onions in Żuławy
How we work

Precision farming, from sowing to storage

We run the whole field with precision farming. It is one of the reasons our yields are high and our work is accurate.

Precise sowing and guidance

We guide our machines with GPS Trimble RTK and John Deere Auto Pilot, accurate to the centimetre. We drive evenly, with no overlaps or gaps, saving seed and fuel.

Variable rate and spot spraying

We apply fertiliser at variable rates, giving each part of the field exactly what it needs. In 2025 we tested the Ecorobotix ARA spot sprayer, which uses cameras to detect weeds and spray only them.

Lifting onions on a Żuławy field

Fast and gentle harvest

A self-propelled harvester lifts the onions two rows at a time, up to 150 tonnes per hour, without damaging the skin. We harvest potatoes and beets with our own machines, each in its own time.

Drying and storage

After harvest we dry the onions for two to four days and keep them in our own store of around 1300 tonnes. That lets us ship for most of the year, not only after the harvest.
