The Grand Prairie diversified into rice agriculture during this period; and remains a major source of rice production. Economic forces also brought change in the Ozarks, where fruit orchards and vineyards more suitable to the soil, climate, and topography had long supplanted row agriculture. As fruit production moved to more productive areas of the United States, a variety of new crops and methods swept across the hills and hollers of the Ozarks. Poultry, dairy, and cattle production spread quickly in Benton and Washington counties, but did not follow into other parts of the Ozarks. Mining and logging were prevalent where natural resources remained available.
