In 1939 Lady Eve Balfour, who had been farming since 1920 in Haughley Green, Suffolk, England, launched the Haughley Experiment. Lady Balfour believed that mankind's health and future depended on how the soil was used, and that non-intensive farming could produce more wholesome food. The experiment was run to generate data to test these beliefs. Four years later, she published "The Living Soil", based on the initial findings of the Haughley Experiment. Widely read, it led to the formation of a key international organic advocacy group, the Soil Association.
