farming which follows practices designed to minimise the human impact on the environment, while ensuring the agricultural system operates as naturally as possible; such practices may include wide crop rotation, very strict limits on chemical synthetic pesticide and synthetic fertiliser use, a prohibition of the use of genetically modified organisms, choosing plant and animal species that are resistant to disease and adapted to local conditions, and raising livestock in free-range, open-air systems and providing them with organic feed, crop production systems that generally exclude the use of synthetic fertilizers, pesticides, and other chemicals, taastuvail loodusvaradel põhinev ja loodusseadusi järgiv taime- ja loomakasvatus, selline põllumajanduslik tootmisviis, kus pööratakse suurt tähelepanu keskkonnahoiule ja ökoloogilisele tasakaalule
