The organic movement broadly refers to the organizations and individuals involved worldwide in the promotion of organic farming and other organic products. It started around the first half of the 20th century, when modern large-scale agricultural practices began to appear.
The term “organic” can be broadly described as food grown without the assistance of man-made chemicals. The term "organic farming" was coined by Lord Northbourne in 1940. The beginnings of the organic movement can be traced back to the beginning of the 1800s. In 1840 Justus Von Liebig developed a theory of mineral plant nutrition. Liebig believed that manure could be directly substituted by certain mineral salts. Many years later in 1910, preceding the First World War, chemists Fritz Haber and Carl Bosch developed an ammonia synthesis process, making use of nitrogen from the atmosphere. This form of ammonia had already been used to manufacture explosives, so after the war, it was implemented into the fertilization of agriculture.
The organic movement began in the early 1900s in response to the shift towards synthetic nitrogen fertilizers and pesticides in the early days of industrial agriculture. A relatively small group of farmers came together in various associations: Demeter International of Germany, which encouraged biodynamic farming and began the first certification program, the Australian Organic Farming and Gardening Society, the Soil Association of the United Kingdom, and Rodale Press in the United States, along with others. In 1972 these organizations joined to form the International Federation of Organic Agriculture Movements (IFOAM). In recent years, environmental awareness has driven demand and conversion to organic farming. Some governments, including the European Union, have begun to support organic farming through agricultural subsidy reform. Organic production and marketing have grown at a fast pace.
