Richard is CEO of Devenish and the farm is used as part of Devenish’s research programme with innovations such as agroforesty, multispecies swards and rewetting peatlands currently being trialled across the unit. The farm is monitoring its carbon footprint from the production of meat and measuring the level of carbon sequestration in the soil over time. Oisin and Rian Kennedy, with farm manager Colin Gavaghan.
