An Agricultural Testament, a book by Sir Albert Howard, is credited by some with launching the organic farmingagriculturalmovement. 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 over than man_made inputs as the superior approach to farming. It was first published in 1940, and is now out of print.

According to the international organic farming organisation IFOAM : The role of organic agriculture, whether in farming, processing, distribution, or consumption, is to sustain and enhance the health of ecosystems and organisms from the smallest in the soil to human beings[1].
An international framework for organic farming is provided by the International Federation of Organic AgricultureMovements (IFOAM), the international democratic umbrella organization established in 1972.
An organic operation that imports the manure it uses to replace the nutrients taken out of the soil by crops, must factor in the resources required to produce and transport that manure, when calculating sustainability.
