The Living Soil (1943) by Lady Eve Balfour is considered a seminal classic in organic agriculture and the organic movement.

[1] The book is based on the initial findings of the first three years of the Haughley Experiment, the first formal, side-by-side farm trial to compare organic and chemical-based farming, started in 1939 by Balfour (with Alice Debenham), on two adjoining farms in Haughley Green, Suffolk, England.

[2][3][4] The Living Soil was also published as The Living Soil and the Haughley Experiment.
