Facsimile of 1940 Edition. An Agricultural Testament is Sir Albert Howard's best-known publication and remains one of the seminal works in the history of organic farming movement. The work focuses on the nature and management of soil fertility, and notably explores composting. At a time when modern, chemical-based industrialized agriculture was just beginning to radically alter food production, it advocated natural processes rather than man-made inputs as the superior approach to farming. It was first published in England in 1940. Since this book first appeared in 1940, it has been regarded as one of the most important contributions to the solution of soil rehabilitation problems ever published. More importantly, it is regarded as the keystone of the organic movement.Louis Bromfield called it "the best book I know on soil and the processes which take part in it." Soil Science called it "the most interesting and suggestive book on soil fertility which has appeared since King's Farmers of Forty Centuries." And Mother Earth News
