Tierra de Campos
Fields of the Leonese Region are arid and dry but very fertile, they dominate in dry farming. Even so, irrigation has become increasingly important in areas of the valleys of the Douro, the Pisuerga and Tormes. The most fertile area coincides with the Leon Valley Esla, Leon, and Tierra de Campos, a region lying between Zamora, Valladolid, Palencia and León.
