The judges said those involved in the farming business brought an incredibly varied complement of skills, plus made a generous contribution to the wider community.

"Management of the business and environment is well thought-out and shared with peers and the wider community. They're exceedingly generous in their involvement with the community – from farm discussion groups to central government".
