Castlemains Farm, East Lothian (Arable)

Bob Simpson and his family farm at Castlemains on the edge of the village of Dirleton, less than two miles west of North Berwick, East Lothian. The arable farm covers 235 hectares with a mix of winter wheat, spring barley, oilseed rape, winter barley, combining peas and brussels sprouts. With a good climate and fertile soil, Castlemains is ideal for a varied crop rotation that helps maintain soil structure and nutrients.

Bob volunteered as a Climate Change Focus Farm from 2014 - 2018. During the course of the project, Bob saved in the region of £14,000 and reduced his carbon footprint by 14%* through practical tweaks to existing practices.
