Agriculture was practiced for thousands of years without the use of artificial chemicals. Artificial fertilizers were first created during the mid-19th century. These early fertilizers were cheap, powerful, and easy to transport in bulk. Similar advances occurred in chemical pesticides in the 1940s, leading to the decade being referred to as the 'pesticide era'.[14] These new agricultural techniques, while beneficial in the short term, had serious longer term side effects such as soil compaction, erosion, and declines in overall soil fertility, along with health concerns about toxic chemicals entering the food supply.[15]:10 In the late 1800s and early 1900s, soil biology scientists began to seek ways to remedy these side effects while still maintaining higher production. Biodynamic agriculture was the first modern system of agriculture to focus exclusively on organic methods.[16][17][18][19]: Its development began in 1924 with a series of eight lectures on agriculture given by Rudolf Steiner.[20][21] These lectures, the first known presentation of what later came to be known as organic agriculture,[16] were held in response to a request by farmers who noticed degraded soil conditions and a deterioration in the health and quality of crops and livestock resulting from the use of chemical fertilizers.[22] The one hundred eleven attendees, less than half of whom were farmers, came from six countries, primarily Germany and Poland.[16] The lectures were published in November 1924; the first English translation appeared in 1928 as The Agriculture Course.[23] In 1921, Albert Howard and his wife Gabrielle Howard, accomplished botanists, founded an Institute of Plant Industry to improve traditional farming methods in India. Among other things, they brought improved implements and improved animal husbandry methods from their scientific training; then by incorporating aspects of the local traditional methods, developed protocalls for the rotation of crops, erosion prevention techniques, and the systematic use of composts and manures.[24] Stimulated by these experiences of traditional farming, when Albert Howard returned to Britain in the early 1930s[25] he began to promulgate a system of natural agriculture. In July 1939, Ehrenfried Pfeiffer, the author of the standard work on biodynamic agriculture (Bio-Dynamic Farming and Gardening),[26] came to the UK at the invitation of Walter James, 4th Baron Northbourne as a presenter at the Betteshanger Summer School and Conference on Biodynamic Farming at Northbourne's farm in Kent.[27] One of the chief purposes of the conference was to bring together the proponents of various approaches to organic agriculture in order that they might cooperate within a larger movement. Howard attended the conference, where he met Pfeiffer.[28] In the following year, Northbourne published his manifesto of organic farming, Look to the Land, in which he coined the term "organic farming." The Betteshanger conference has been described as the 'missing link' between biodynamic agriculture and other forms of organic farming.[27] In 1940 Howard published his An Agricultural Testament. In this book he adopted Northbourne's terminology of "organic farming."[29] Howard's work spread widely, and he became known as the "father of organic farming" for his work in applying scientific knowledge and principles to various traditional and natural methods.[15]:45 In the United States J.I. Rodale, who was keenly interested both in Howard's ideas and in biodynamics,[30] founded in the 1940s both a working organic farm for trials and experimentation, The Rodale Institute, and the Rodale Press to teach and advocate organic methods to the wider public. These became important influences on the spread of organic agriculture. Further work was done by Lady Eve Balfour in the United Kingdom, and many others across the world. Increasing environmental awareness in the general population in modern times has transformed the originally supply-driven organic movement to a demand-driven one. Premium prices and some government subsidies attracted farmers. In the developing world, many producers farm according to traditional methods that are comparable to organic farming, but not certified, and that may not include the latest scientific advancements in organic agriculture. In other cases, farmers in the developing world have converted to modern organic methods for economic reasons.[31]
