Agriculture and wildlife Much of the land in the San Luis Valley is used for grazing. Farming is generally concentrated around the towns of Alamosa, Monte Vista and Center. Principal crops include potatoes, head lettuce, wheat, and barley. The barley grown here is the main supplier for Coors beer company. In 1982, quinoa was successfully grown for the first time outside of South America in the San Luis Valley of Colorado, and commercial growth has occurred since 1987. Less favored areas with a shorter growing season and less access to water rights tend to be devoted to alfalfa and grazing. Broad areas, especially in Saguache County, Colorado have a high water table or are even flooded part of the year. Uncultivated land is often covered with "chico", low brush such as rabbitbrush, greasewood and other woody species. Cropland is typically irrigated with large ( mile radius) center-pivot irrigation systems, and a common feature of the Rio Grande Delta area where the Rio Grande enters the valley are large piles of potato-sized rocks screened from the soil.
