With world markets upset and economies in recession, the 1920s and '30s were not an easy time for farmers, who required great resilience to survive.Jonathan Brown here examines the challenges that farmers faced and the ways in which they responded.Some turned to new crops, with new markets emerging for sugar beet, eggs, milk and pork.Some used tractors and other machines to increase productivity, and the motor car and lorry opened up new possibilities for bringing produce to market.It was hard work whichever direction was taken, but the effects of these innovations was undeniably beneficial and the farming landscape was transformed from what it had been in Victorian and Edwardian times.
