Migrants from the southern Appalachians settled the forested Ozark Plateau and Ouachita Mountains in the early 19th century. Meanwhile, rich black soils along the Mississippi River attracted cotton planters to the east and south. Arkansas now leads the nation in rice, ranks third in turkeys, and places high in soybeans and sorghum. No other place in the world produces more bromine. Hot Springs National Park and the scenic Ozarks attract a growing number of visitors.
