Gleadell Agriculture

Dunns was privately owned until February 2012, when its shares were purchased by Gleadell Agriculture – the UK’s leading independent agricultural merchant.

Gleadell is jointly owned by ADM and InVivo. This gives fantastic financial security to both Gleadell and Dunns, as well as access to worldwide market information.

Collaborating closely with international and UK breeders we have secured access to new up-and-coming seed varieties for our farmer and consumer customers.

Dunns have access to market leading pea varieties that are sought after by many large pulse consumers. Our aim is to provide excellent service, with efficient collection and delivery followed by prompt payment.

Investing in the future

Dunns moved site from the centre of Long Sutton to a green field site in 1996, this allowed Dunns to sculpt a bespoke site specifically suited to its needs.

Dunns has invested significantly on the site in recent years, building 3 new stores, 2 new production lines and an automatic bag placer and palletiser in the last 7 years alone. This allows Dunns to process and store seed and pulses in different locations, eliminating the risk of cross contamination.
