- "Organic farming depends on encouraging a diverse ecosystem to maintain soil fertility and to keep pests under control naturally. It does this by encouraging nature’s own predators by maintaining hedgerows and creating open, ‘wild’ spaces at the side of fields, and changing the crops planted each season, to keep soil fertile and avoid the need for chemicals."
