The Pampas (from Quechua, meaning "plain") are the fertile South American lowlands that include the Argentine provinces of Buenos Aires, La Pampa, Santa Fe, and Córdoba, most of Uruguay, and the southernmost end of Brazil, Rio Grande do Sul, covering more than 750,000 km² (290,000 square miles). These vast plains are only interrupted by the low Ventania mountain range near BahÃa Blanca (Argentina), with 1,300 m height. The climate is mild, with precipitation of 600 to 1,200 mm, more or less evenly distributed through the year, making the soils appropriate for agriculture.
