Traditional farming (of many particular kinds in different eras and places) was the original type of agriculture, and has been practiced for thousands of years. All traditional farming is now considered to be "organic farming" although at the time there were no known inorganic methods. For example, forest gardening, a fully organic food production system which dates from prehistoric times, is thought to be the world's oldest and most resilient agroecosystem. [1] The industrial revolution introduced inorganic methods, most of which were not well developed and had serious side effects. An organic movement began in the 1940s as a reaction to agriculture's growing reliance on synthetic fertilizers and pesticides. The history of this modern revival of organic farming dates back to the first half of the 20th century at a time when there was a growing reliance on these new synthetic, non-organic methods.
The first 40 years of the 20th century saw simultaneous advances in biochemistry and engineering that rapidly and profoundly changed farming. The introduction of the gasoline-powered internal combustion engine ushered in the era of the tractor and made possible hundreds of mechanized farm implements. Research in plant breeding led to the commercialization of hybrid seed. And a new manufacturing process made nitrogen fertilizer — first synthesized in the mid-19th century [2] — affordably abundant. These factors changed the labour equation: there were almost no tractors in the US around 1910, but over 3,000,000 by 1950; in 1900, it took one farmer to feed 2.5 people, but currently the ratio is 1 to well over 100. Fields grew bigger and cropping more specialized to make more efficient use of machinery. The reduced need for manual labour and animal labour that machinery, herbicides, and fertilizers made possible created an era in which the mechanization of agriculture evolved rapidly.
Consciously organic agriculture (as opposed to traditional agricultural methods from before the inorganic options existed, which always employed only organic means) began more or less simultaneously in Central Europe and India. The British botanist Sir Albert Howard is often referred to as the father of modern organic agriculture, because he was the first to apply modern scientific knowledge and methods to traditional agriculture. From 1905 to 1924, he and his wife Gabrielle, herself a plant physiologist, worked as agricultural advisers in Pusa, Bengal, where they documented traditional Indian farming practices and came to regard them as superior to their conventional agriculture science. Their research and further development of these methods is recorded in his writings, notably, his 1940 book, An Agricultural Testament , which influenced many scientists and farmers of the day.
In Germany, Rudolf Steiner's development, biodynamic agriculture, was probably the first comprehensive system of what we now call organic farming. This began with a lecture series Steiner presented at a farm in Koberwitz (Kobierzyce now in Poland) in 1924. [3] Steiner emphasized the farmer's role in guiding and balancing the interaction of the animals, plants and soil. Healthy animals depended upon healthy plants (for their food), healthy plants upon healthy soil, healthy soil upon healthy animals (for the manure). [4] [5] [6] [7] His system was based on his philosophy of anthroposophy rather than a good understanding of science. [4] : 17–19 To develop his system of farming, Steiner established an international research group called the Agricultural Experimental Circle of Anthroposophical Farmers and Gardeners of the General Anthroposophical Society. [8]
In 1909, American agronomist F.H. King toured China, Korea, and Japan, studying traditional fertilization, tillage, and general farming practices. He published his findings in Farmers of Forty Centuries (1911, Courier Dover Publications, ISBN 0-486-43609-8). King foresaw a "world movement for the introduction of new and improved methods" [9] of agriculture and in later years his book became an important organic reference.
The term "organic farming" was coined by Walter James (Lord Northbourne), a student of Biodynamic Agriculture, in his book Look to the Land (written in 1939, published 1940). [10] [11] In this text, James described a holistic, ecologically balanced approach to farming, "the farm as organism," [12] basing this on Steiner's agricultural principles and methods. One year previously to his book's publication, James had hosted the first Biodynamic Agriculture conference in England, the Betteshanger Summer School and Conference, at which Ehrenfried Pfeiffer was the key presenter. [11]
In 1939 James, Albert Howard, Ehrenfried Pfeiffer and George Stapleton joined at Farleigh to implement an experiment comparing Biodynamic, organic and chemical fertilization methods. "The Farleigh Experiment", had been planned since initial meetings in 1936 including ten participants. The experiment was cut short due to the fact that Biodynamic compost was not available until after the Betteshanger Summer School event, the disruption of the impending war, and lack of funding. Though inconclusive, this experiment was seen as providing impetus for the similar "Haughley Experiment" described below.
In 1939 Lady Eve Balfour, who had been farming since 1920 in Haughley Green, Suffolk, England, launched the Haughley Experiment. Lady Balfour believed that mankind's health and future depended on how the soil was used, and that non-intensive farming could produce more wholesome food. The experiment was run to generate data to test these beliefs. [13] Four years later, she published The Living Soil , based on the initial findings of the Haughley Experiment. Widely read, it led to the formation of a key international organic advocacy group, the Soil Association.
In Japan, Masanobu Fukuoka, a microbiologist working in soil science and plant pathology, began to doubt the modern agricultural movement. In 1937, he quit his job as a research scientist, returned to his family's farm in 1938, and devoted the next 60 years to developing a radical no-till organic method for growing grain and many other crops, now known as natural farming (自然農法, shizen nōhō), nature farming, 'do–nothing' farming or Fukuoka farming.
Technological advances during World War II accelerated post-war innovation in all aspects of agriculture, resulting in large advances in mechanization (including large-scale irrigation), fertilization, and pesticides. In particular, two chemicals that had been produced in quantity for warfare, were repurposed for peacetime agricultural uses. Ammonium nitrate, used in munitions, became an abundantly cheap source of nitrogen. And a range of new pesticides appeared: DDT, which had been used to control disease-carrying insects around troops, became a general insecticide, launching the era of widespread pesticide use.
At the same time, increasingly powerful and sophisticated farm machinery allowed a single farmer to work larger areas of land and fields grew bigger.
In 1944, an international campaign called the Green Revolution was launched in Mexico with private funding from the US. It encouraged the development of hybrid plants, chemical controls, large-scale irrigation, and heavy mechanization in agriculture around the world.
During the 1950s, sustainable agriculture was a topic of scientific interest, but research tended to concentrate on developing the new chemical approaches. One of the reasons for this, which informed and guided the ongoing Green Revolution, was the widespread belief that high global population growth, which was demonstrably occurring, would soon create worldwide food shortages unless humankind could rescue itself through ever higher agricultural technology. At the same time, however, the adverse effects of "modern" farming continued to kindle a small but growing organic movement. For example, in the U.S., J. I. Rodale began to popularize the term and methods of organic growing, particularly to consumers through promotion of organic gardening.
In 1962, Rachel Carson, a prominent scientist and naturalist, published Silent Spring , chronicling the effects of DDT and other pesticides on the environment. [14] A bestseller in many countries, including the US, and widely read around the world, Silent Spring is widely considered as being a key factor in the US government's 1972 banning of DDT. The book and its author are often credited with launching the worldwide environmental movement.
In the 1970s, global movements concerned with pollution and the environment increased their focus on organic farming. As the distinction between organic and conventional food became clearer, one goal of the organic movement was to encourage consumption of locally grown food, which was promoted through slogans like "Know Your Farmer, Know Your Food".
An early organic farmers' association, the Maine Organic Farmers and Gardeners Association was founded in 1971. [15]
In 1972, the International Federation of Organic Agriculture Movements (IFOAM) was founded in Versailles, [16] France and dedicated to the diffusion and exchange of information on the principles and practices of organic agriculture of all schools and across national and linguistic boundaries.
In 1975, Fukuoka released his book, The One-Straw Revolution , with a strong impact in certain areas of the agricultural world. His approach to small-scale grain production emphasized a meticulous balance of the local farming ecosystem, and a minimum of human interference and labour.
In the U.S. during the 1970s and 1980s, J. I. Rodale and his Rodale Press (now Rodale, Inc.) advocated for organic farming methods. The press's books offered how-to information and advice to Americans interested in trying organic gardening and farming.
In 1984, Oregon Tilth established an early organic certification service in the United States. [17]
In the 1980s, around the world, farming and consumer groups began seriously pressuring for government regulation of organic production. This led to legislation and certification standards being enacted through the 1990s and to date. In the United States, the Organic Foods Production Act of 1990 tasked the USDA with developing national standards for organic products, and the final rule establishing the National Organic Program was first published in the Federal Register in 2000. [18]
In Havana, Cuba, the loss of Soviet economic support following the collapse of the Soviet Union in 1991 led to a focus on local agricultural production and the development of a unique state-supported urban organic agriculture program called organopónicos.
Since the early 1990s, the retail market for organic farming in developed economies has been growing by about 20% annually due to increasing consumer demand. Concern for the quality and safety of food, and the potential for environmental damage from conventional agriculture, are apparently responsible for this trend.
Organic farming, also known as organic agriculture or ecological farming or biological farming, is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction to rapidly changing farming practices. Indeed, so-called "organic pioneers" wanted to keep farming with nature, without being dependent on external inputs. Certified organic agriculture accounts for 70 million hectares globally, with over half of that total in Australia. Biological pest control, mixed cropping, and the fostering of insect predators are encouraged. Organic standards are designed to allow the use of naturally-occurring substances while prohibiting or severely limiting synthetic substances. For instance, naturally-occurring pesticides such as garlic extract, bicarbonate of soda, or pyrethrin which is found naturally in the Chrysanthemum flower are permitted, while synthetic fertilizers and pesticides such as glyphosate are prohibited. Synthetic substances that are allowed, only in exceptional circumstances, include, for example, copper sulfate, elemental sulfur, and veterinary drugs. Genetically modified organisms, nanomaterials, human sewage sludge, plant growth regulators, hormones, and antibiotic use in livestock husbandry are prohibited. Organic farming positively impacts sustainability, self-sufficiency, autonomy and independence, health, animal welfare, food security, and food safety. Organic farming can therefore be seen as part of the solution to the impacts of climate change, as also established by the Food and Agriculture Organisation (FAO).
The following outline is provided as an overview of and topical guide to organic gardening and farming:
The organic movement broadly refers to the organizations and individuals involved worldwide in the promotion of organic food and other organic products. It started during the first half of the 20th century, when modern large-scale agricultural practices began to appear.
The Soil Association is a British registered charity focused on the effect of agriculture on the environment. It was established in 1946. Their activities include campaigning for local purchasing, public education on nutrition and certification of organic foods, and against intensive farming.
Lady Evelyn Barbara Balfour, was a British farmer, educator, organic farming pioneer, and a founding figure in the organic movement. She was one of the first women to study agriculture at an English university, graduating from the institution now known as the University of Reading.
The Haughley Experiment was the first comparison of organic farming and conventional farming, started in 1939 by Lady Eve Balfour and Alice Debenham, on two adjoining farms in Haughley Green, Suffolk, England. It was based on an idea that farmers were over-reliant on fertilizers, that livestock, crops and the soil should be treated as a whole system, and that "natural" farming produced food which was in some way more wholesome than food produced with more intensive methods. Lady Balfour believed that mankind's future and human health were dependent on how the soil was treated, and ran the experiment to generate scientific data that would support these beliefs.
Sir Albert Howard was an English botanist. His academic background might have been botany. While working in India he was generally considered a pathologist; this more than likely being the reason for his consistent observations of the value of compost applications being an increase in health. Howard was the first Westerner to document and publish the Indian techniques of sustainable agriculture. After spending considerable time learning from Indian peasants and the pests present in their soil, he called these two his professors. He was a principal figure in the early organic movement. He is considered by many in the English-speaking world to have been, along with Eve Balfour, one of the key advocates of ancient Indian techniques of organic agriculture.
Biodynamic agriculture is a form of alternative agriculture based on pseudo-scientific and esoteric concepts initially developed in 1924 by Rudolf Steiner (1861–1925). It was the first of the organic farming movements. It treats soil fertility, plant growth, and livestock care as ecologically interrelated tasks, emphasizing spiritual and mystical perspectives.
Biodynamic wines are wines made employing the biodynamic methods both to grow the fruit and during the post-harvest processing. Biodynamic wine production uses organic farming methods while also employing soil supplements prepared according to Rudolf Steiner's formulas, following a planting calendar that depends upon astrological configurations, and treating the earth as "a living and receptive organism."
Organic horticulture is the science and art of growing fruits, vegetables, flowers, or ornamental plants by following the essential principles of organic agriculture in soil building and conservation, pest management, and heirloom variety preservation.
The Biodynamic Federation Demeter International is the largest certification organization for biodynamic agriculture Its name is a reference to Demeter, the Greek goddess of grain and fertility. It is a non-profit umbrella organisation with 46 members organisations in 36 countries, and over participating 6,500 farmers around the world, representing both the global biodynamic movement and the Demeter certified biodynamic farms. The organization incorporates 19 certifying Demeter organizations, and the rest of the certification is done by the international certification committee.
Ehrenfried Pfeiffer was a German scientist, soil scientist, leading advocate of biodynamic agriculture, anthroposophist and student of Rudolf Steiner.
The Biodynamic Association is a United States–based company that promotes Biodynamic agriculture system through educational and research programs and has headquarters in Milwaukee, Wisconsin.
Walter Ernest Christopher James, 4th Baron Northbourne, was an English agriculturalist, author and rower who competed in the 1920 Summer Olympics.
The Wild Farm Alliance (WFA) is a non-profit organization dedicated to increasing biodiversity by expanding the idea and practice of wild farming.
Wild farming is a growing alternative to "factory farming" that consists of planting crops that are highly associated and supportive to the natural ecosystem. This includes intercropping with native plants, following the contours and geography of the land, and supporting local food chains. The goal is to produce large crop yields, while still promoting a healthy environment. Wild farming is a backlash against the dominance of factory farming which is a dominant factor in the food industry and has a 'myth' that industrial agriculture is more efficient. Up until the mid 20th century, agricultural crop yields relied on natural inputs such as rainfall patterns, natural soil resources, recycling of organic matter, and built-in biological control mechanisms. Currently, agricultural practices have been conventionalized to include large monocropped fields and the use of synthetic pesticides and fertilizers. Avoiding the conventional farming practices, wild farming adopts many practices from sustainable agricultural systems such as agroecology, permaculture, forest farming, and greywater systems.
Organic food, ecological food, or biological food are foods and drinks produced by methods complying with the standards of organic farming. Standards vary worldwide, but organic farming features practices that cycle resources, promote ecological balance, and conserve biodiversity. Organizations regulating organic products may restrict the use of certain pesticides and fertilizers in the farming methods used to produce such products. Organic foods are typically not processed using irradiation, industrial solvents, or synthetic food additives.
The effect of organic farming has been a subject of interest for researchers. Theory suggests that organic farming practices, which exclude the use of most synthetic pesticides and fertilizers, may be beneficial for biodiversity. This is generally shown to be true for soils scaled to the area of cultivated land, where species abundance is, on average, 30% richer than that of conventional farms. However, for crop yield-scaled land the effect of organic farming on biodiversity is highly debated due to the significantly lower yields compared to conventional farms.
Rodale Institute is a non-profit organization that supports research into organic farming. It was founded in Emmaus, Pennsylvania in 1947 by J. I. Rodale, an organic living entrepreneur. After J.I. Rodale died in 1971, his son Robert Rodale purchased 333 acres and moved the farm to Kutztown, Pennsylvania.
Patrick Holden, is a UK organic dairy farmer, campaigner for sustainable food and farming, and co-founder with Anthony Rodale of U.K. The Sustainable Food Trust and U.S. Sustainable Food Alliance.
Organic agriculture can be traced back to the early 20th century, initiated by the Austrian spiritual philosopher Rudolf Steiner.
