The purpose of this book is to draw attention to the destruction of the earth's capital - the soil; to indicate some of the consequences of this; and to suggest methods by which the lost fertility can be restored and maintained. "An Agricultural Testament" is Sir Albert Howard's best-known publication, and remains one of the seminal works in the history of organic farming agricultural movement. Dedicated to his first wife and co-worker, herself a plant phsyiologist, it 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.
