HISTORY
HISTORY
The Kerr family has farmed at Easton since 1939, when Alastair’s grandfather, Willie Kerr, moved from Ayrshire, Scotland, to establish himself as a tenant farmer in Suffolk. Over time, the farm expanded under Willie and later expanded by his son, John Kerr, housing two dairy farms and inventing the Kerr curved tooth harrow.
In 1972, Willie helped form the Suffolk Farming and Wildlife Advisory Group (FWAG) and introduced the Kerr Cup to honour farms excelling in conservation. This initiative was ground breaking at a time when conservation was not widely regarded as integral to farming practices. Beyond farming, Willie and John Kerr were deeply involved with Ipswich Town Football Club. Both served as directors, and John held the position of chairman during the club’s promotion to the Premier League in 1992.

FARMING AT ALTERRA FARMS
FARMING AT ALTERRA FARMS
Food production has always been at the heart of the business, with the farm growing wheat, barley, oilseed rape, sugar beet, and vining peas. At one point, the farm operated two dairy herds with around 250 cows and a beef herd. However, due to the economics of milk production in the UK, these operations ceased nearly 30 years ago. While there is no commercial livestock on the farm today, there is a strong desire to reintroduce livestock at an extensive level in the future.
The low-lying water meadows along the banks of the River Deben provide ideal conditions for growing cricket bat willow trees. These are cultivated commercially, with cricket legends Sir Ian Botham and Sir Alastair Cook both previously planting trees on the farm to support fundraising efforts for Beefy’s Foundation.
