Organic farming is the form of agriculture that relies on crop rotation, compost, biological pest control, mechanical cultivation, and other techniques using natural processes, to maintain soil productivity and control pests. Organic farming excludes or strictly limits the use of synthetic fertilizers, pesticides, and livestock feed additives. Genetically modified organisms are excluded, and organic standards in Britain and Australia exclude engineered nanoparticles.
"Organic agriculture is a production system that sustains the health of soils, ecosystems and people. It relies on ecological processes, biodiversity and cycles adapted to local conditions, rather than the use of inputs with adverse effects. Organic agriculture combines tradition, innovation and science to benefit the shared environment and promote fair relationships and a good quality of life for all involved..." -- International Federation of Organic Agriculture Movements

- Weeds are controlled with management practices and lots of work.
- Garden pests are handled with integrated pest management practices which include biological, physical, and mechanical controls.
- Some organic pesticides are permitted.
