A “poor sheep walk” in the hills of Dolfor, Montgomeryshire, is transformed during WWII into a luxuriant pasture after being ploughed up, fertilized and re-seeded. Ion Trant, Welshpool farmer/film-maker and a member of the county’s War Agricultural Executive Committee, exhorts fellow farmers to aim for the green, green grass of Dolfor themselves. For the cost of about £11 an acre they too can increase the land available for food production.
