Organic farming

language culture Maturity 9-11 Next article →

Organic farming is an integrated agricultural system designed for sustainability. It focuses on enhancing soil fertility and biological diversity. This method relies on naturally occurring, non-synthetic inputs. Farmers avoid most man-made chemicals to protect the environment. Instead, they use biological processes to manage their land. This approach is built on principles of health, ecology, and fairness. Many see it as a solution to the impacts of climate change.

To manage a farm organically, practitioners use specific mechanical and biological techniques. One key method is crop rotation, where different plants are grown in sequence. This helps to renew soil nutrients and confuse pests. Farmers also use companion planting and mixed cropping to support plant health. Nitrogen is often added to the soil through legumes. Natural materials like compost, manure, and bone meal provide essential nutrients. For pest control, farmers use biological methods like fostering insect predators. They may also use natural substances like garlic extract or pyrethrin. Pyrethrin is a substance found naturally in the Chrysanthemum flower.

Organic standards include strict rules about what can and cannot be used. Most synthetic pesticides and fertilizers are prohibited. For example, the synthetic pesticide glyphosate is not allowed. However, some naturally occurring substances are permitted. These include bicarbonate of soda and potassium bicarbonate, which can act as a fungicide. In very rare and exceptional circumstances, certain substances like copper sulfate or elemental sulfur may be used. Most importantly, genetically modified organisms (GMOs) are excluded from organic systems. Other prohibited items include nanomaterials, human sewage sludge, and growth hormones. In livestock, the use of antibiotics is also restricted.

The history of organic farming began as a reaction to industrial changes. In the mid-19th century, artificial fertilizers were first developed. These were cheap and easy to transport in large amounts. By the 1940s, the "pesticide era" arrived with new chemical sprays. While these helped in the short term, they caused long-term problems. These issues included soil erosion, soil compaction, and declining soil fertility. Scientists also worried about toxic chemicals entering the food supply. In response, pioneers began looking for ways to maintain production using natural methods.

Several key figures helped shape the modern organic movement. In 1921, Albert Howard and his wife Gabrielle founded an Institute of Plant Industry in India. They combined scientific training with traditional Indian methods. They developed protocols for using compost and preventing erosion. Albert Howard is now known as the "father of organic farming." Around the same time, Rudolf Steiner gave lectures on biodynamic agriculture. This approach views the farm as a living organism. In 1940, Howard published "An Agricultural Testament," adopting the term "organic farming." In the United States, J. I. Rodale helped spread these ideas through the Rodale Institute.

Today, organic farming is a massive global industry with significant economic value. In 2022, the global market for organic products reached $150 billion. North America earned more than $64 billion of this total. Europe earned approximately EUR 53 billion. As of 2022, organic farming is practiced in 188 different countries. There are about 4.5 million organic farmers working worldwide. These farmers manage approximately 2 percent of all global farmland. Demand is growing rapidly, as organic farmland increased by 26.6 percent between 2021 and 2022.

Organic agriculture connects to several broader scientific and social fields. It is closely studied within the field of agroecology. This science looks at how farming interacts with natural ecosystems. The movement is also regulated by transnational organizations like the European Union. Much of the global standard-setting is done by IFOAM. This is an international umbrella organization established in 1972. While organic farming protects local biodiversity, it faces unique challenges. Because organic yields can be lower than intensive farming, it may require more land. This can create pressure to convert non-agricultural land into farms.
