Our trial fields

Quality starts here

Across multiple trial locations in Friesland, we conduct around 2,500 field trials each year. Selection in the field, confidence on the shelf.
  • Careful evaluation of varieties for colour, shape and size
  • Rigorous selection to safeguard varietal purity
  • Cultivation of foundation stock for further seed multiplication
Our Greenhouse:

Cultivation under our own management

With 6,000 m² of greenhouse space across two locations, we work proactively to build a healthy foundation for strong, vigorous plants. A solid cultivation base is the cornerstone of consistent quality.
  • Our focus lies primarily on maintaining
    open-pollinated varieties, heritage cultivars that are naturally pollinated and carefully preserved.
  • Biological crop protection is an integral part of our approach.
Our Laboratory:

Quality control as standard

In our laboratory, we carry out approximately 9,000 tests each year to safeguard the quality of every single seed. This is how we ensure consistent performance, batch after batch.
  • Germination testing tailored to each crop, in accordance with internationally recognised ISTA protocols
  • Newly harvested seed lots are immediately tested for purity and germination
  • Existing stock is re-evaluated periodically to guarantee ongoing quality
Our Cleaning Facility:

Purity, down to the finest detail

In our cleaning facility, every impurity is meticulously removed from the seed. Soil, plant debris and weed seeds are carefully separated, leaving only the highest quality seed behind.
  • With 18 specialised machines, including advanced technologies such as optical colour sorting, we process each lot with maximum precision.
  • Approximately 250,000 kilograms of seed are processed each year.
Our Conditioned Warehouse:

Optimal conditions for maximum quality

In our warehouse, seeds are stored under carefully controlled conditions to preserve both quality and germination capacity. This allows us to maintain consistent performance as well as reliable delivery.
  • Conditioned storage at 17 °C and 30% relative humidity
  • Strict batch coding and barcoding to ensure full traceability
Our Machinery:

Production fully managed
in-house

With 18 packaging lines, we ensure a fast and carefully controlled process. On average, we produce 60 million seed packets each year. This enables us to guarantee continuity, even at high volumes.
  • Each machine automatically folds, seals, cuts and fills every packet
  • Precise filling by weight or by seed count
  • Production codes and expiry dates printed directly during the process
Our Distribution Center:

Availability as a priority

From our distribution centre, we manage 10,000 m² of warehousing and order fulfilment. This enables us to guarantee reliable delivery, even during peak season.
  • Up to 1,000 orders per Up to 1,000 orders per week in high season in the high season
  • 3,500 finished products and approximately 2,000 semi-finished products kept in stock
