High traceability

We take care of the entire chain from production to packaging. Therefore we always know the origin of our seeds.

Extensive quality control

To ensure the quality of our seeds, we apply a strict quality check on all our seed lots. First, we select the best and experienced organic growers. Most of the growers we work with, have several years of experience in growing the specific crops. Moreover, we focus on long-term collaboration with these growers to mutually improve the seed productions where possible. Second, all our seed productions are under our own supervision. We regularly visit the production locations and check on diseases and good uniformity. Obviously, we subsequently apply selection on these seed productions when necessary. Moreover, we conduct disease checks on seed lots in collaboration with NAK tuinbouw (agriculture). You can read more about this organisation on www.naktuinbouw.com  Finally, we perform germination tests for all seed lots each year.

Sprouting seeds

All sprouting seeds at De Bolster are produced, cleaned, stored and packed according to strict HACCP criteria. Moreover, we conduct microbiological tests on all seed lots. We work together with an accredited lab who conducts these laboratory tests according to EU regulations. The following tests are conducted: Salmonella spp, E.Coli (VTEC/STEC) and L. Monocytogenes. For more information on this, please contact our Manager Breeding, Maarten Vosselman (mvosselman@bolster.nl).
