Benefits of Organic Farming



Organic farming is a form of agriculture that relies on sustainable techniques to enhance the natural fertility of a farm, including crop rotation, companion planting, biological pest control, and naturally-sourced fertilisers such as compost, manure, green manure, and bone meal.
Pest-control measures such as mixed crops and fostering natural insect predators, as well as naturally-sourced pesticides such as pyrethrin, are employed, while it excludes or BIO strictly limits the use of synthetic petrochemical fertilisers and pesticides, plant growth regulators such as hormones, antibiotic use in livestock, genetically modified organisms; human sewage sludge, and nano materials.
The agricultural approach emphasises sustainability, openness, independence, health, and safety.
The conservation of natural resources and biodiversity is a core principle of organic production. Three broad management practices (prohibition/reduced use of chemical pesticides and inorganic fertilisers; sympathetic management of non-cropped habitats; and preservation of mixed farming) that are largely intrinsic (but not exclusive) to organic farming are particularly beneficial for farmland wildlife.
In a research report, “Does organic farming benefit biodiversity?”, using practices that attract or introduce beneficial insects, provide habitat for birds and mammals, and provide conditions that increase soil biotic diversity serve to supply vital ecological services to organic production systems.
Advantages to certified organic operations that implement these types of production practices include: decreased dependence on outside fertility inputs; reduced pest management costs; more reliable sources of clean water; and better pollination.

·         Nearly all non-crop, naturally occurring species observed in comparative farm land practice studies show a preference for organic farming both by abundance and diversity.
·         An average of 30 percent more species inhabits organic farms. Birds, butterflies, soil microbes, beetles, earthworms, spiders, vegetation, and mammals are particularly affected.
·         Lack of herbicides and pesticides improve biodiversity fitness and population density. Many weed species attract beneficial insects that improve soil qualities and forage on weed pests.
·         Soil-bound organisms often benefit because of increased bacteria populations due to natural fertiliser such as manure, while experiencing reduced intake of herbicides and pesticides.
·         Increased biodiversity, especially from beneficial soil microbes and mycorrhizae have been proposed as an explanation for the high yields experienced by some organic plots, especially in light of the differences seen in a 21-year comparison of organic and control fields.
·         Biodiversity from organic farming provides capital to humans. Species found in organic farms enhance sustainability by reducing human input (e.g., fertilisers, pesticides).
Organic agricultural methods are internationally regulated and legally enforced by many nations, based in large part on the standards set by the International Federation of Organic Agriculture Movements (IFOAM), an international umbrella organisation for organic farming organisations established in 1972.
