Organic methods reduce some of these costs. 72. Further work was done by Lady Eve Balfour (the Haughley Experiment) in the United Kingdom, and many others across the world. Suckling mammals must be fed with natural, preferably maternal, milk. :[96] In 2005 168,000 ha (415,000 ac) of land in Poland was under organic management. (2008). The feed should primarily be obtained from the farm where the animals are kept or from farms in the same region. Varieties of bacteria and fungi break down chemicals, plant matter and animal waste into productive soil nutrients. A few selective bioherbicides based on fungal pathogens have also been developed. Organic weed management promotes weed suppression, rather than weed elimination, by enhancing crop competition and phytotoxic effects on weeds. [59]:7 Europe farms 23 percent of global organic farmland (6,900,000 ha (17,000,000 acres)), followed by Latin America and the Caribbean with 20 percent (6,400,000 ha (16,000,000 acres)). [158] The researchers concluded that public debate should consider various manners of employing conventional or organic farming, and not merely debate conventional farming as opposed to organic farming. [59]:6 As of 2007 Australasia has 39% of the total organic farmland, including Australia's 11,800,000 hectares (29,000,000 acres) but 97 percent of this land is sprawling rangeland (2007:35). Also, horses and cattle were once a basic farm feature that provided labour, for hauling and plowing, fertility, through recycling of manure, and fuel, in the form of food for farmers and other animals. Interior, No. 6. 544 pp. Praying mantis tend to move more slowly and eat less heavily. This study's methodology and results were contested by D.J. In 2009, the proportion of organic land in the EU grew to 4.7%.

Committee on the Role of Alternative Farming Methods in Modern Production Agriculture, National Research Council. [120] For example, two studies - both comparing organically- versus conventionally-farmed apples - declare contradicting results, one saying organic farming is more energy efficient, the other saying conventionally is more efficient. In addition, organic foods currently enjoy a price premium over conventionally produced foods, meaning that organic farmers can often get more for their yield. [3] For instance, naturally occurring pesticides such as pyrethrin and rotenone are permitted, while synthetic fertilizers and pesticides are generally prohibited. [103] Between 2013 and 2014, organic agricultural land grew by 500,000 hectares worldwide, increasing in every region except Latin America. [103] As of 2014, the country with the most organic land was Australia (17.2 million hectares), followed by Argentina (3.1 million hectares), and the United States (2.2 million hectares). agri-environment schemes); (2) Many comparative studies encounter methodological problems, limiting their ability to draw quantitative conclusions; (3) Our knowledge of the impacts of organic farming in pastoral and upland agriculture is limited; (4) There remains a pressing need for longitudinal, system-level studies in order to address these issues and to fill in the gaps in our knowledge of the impacts of organic farming, before a full appraisal of its potential role in biodiversity conservation in agroecosystems can be made. Independent certification initiatives such as the Agricultural Justice Project, Domestic Fair Trade Working Group, and the Food Alliance have attempted to implement farmworker interests but because these initiatives require voluntary participation of organic farms, their standards cannot be widely enforced. [196] The final guidance also clarifies the role of certified operations (to submit an OSP to a certifier), certifiers (ensure that the OSP describes or lists practices that explain the operator's monitoring plan and practices to support natural resources and biodiversity conservation), and inspectors (onsite inspection) in the implementation and verification of these production practices. Organic wine has to be made with organic grapes and yeast, however, there are a number of other restrictions that also apply. By 2002, this was US$23 billion and by 2015 more than US$43 billion. [71], Synthetic pesticides allowed for use on organic farms include insecticidal soaps and horticultural oils for insect management; and Bordeaux mixture, copper hydroxide and sodium bicarbonate for managing fungi. Once certified by the USDA it can fall into one of four categories: "100 percent organic", "organic", "made with organic ingredients", or "made with less than 70 percent organic ingredients. Positive externalities include self-reliance, entrepreneurship, respect for nature, and air quality. Agriculture was practiced for thousands of years without the use of artificial chemicals. It also found that "significantly less fossil energy was expended to produce corn in the Rodale Institute’s organic animal and organic legume systems than in the conventional production system. Organic food products are grown under a system of agriculture without the use of harmful chemical fertilizers and pesticides with an environmentally and socially responsible approach. : a systematic review", http://www.adb.org/sites/default/files/publication/161042/organic-agriculture-and-post-2015-development-goals, The lowdown on topsoil: it's disappearing, « 100 arguments en faveur de l’agriculture biologique », 10.1890/1051-0761(2006)016[2011:BDADSS]2.0.CO;2, "Ecology of Earthworms under the 'Haughley Experiment' of Organic and Conventional Management Regimes", "USDSA Guidance Natural Resources and Biodiversity Conservation", "Organic fields sustain weed metacommunity dynamics in farmland landscapes", Aijuan Chen. [160] "The carbon sequestration efficiency of organic systems in temperate climates is almost double (575–700 kg carbon per ha per year – 510–625 lb/ac/an ) that of conventional treatment of soils, mainly owing to the use of grass clovers for feed and of cover crops in organic rotations.
