Oat production is concentrated in cold climate regions like the European Union, Canada, Russia, Australia, the United States, and Argentina, with Argentina being the second-largest producer after Russia. The province of Buenos Aires is the leading oat-producing region in Argentina, primarily for export, while La Pampa is the second-largest producer, mainly for local use by cattle farmers. Oats are preferred by livestock producers as an alternative to winter greening due to their adaptability, easy production, and soil protection properties.
