органско земјоделство

органско земјоделство

There is no universally accepted definition of organic farming, and each country regulates what can and cannot be labelled "organic". In general, it describes a form of agriculture that avoids use of synthetic fertilisers, pesticides, growth regulators, and livestock feed additives, and relies instead, as far as possible, on "natural" products and techniques - such as crop rotation and animal manures.
