The country of Olmantia has generally relied on growing soybeans as an export. Recently, the ministry of agriculture has implemented a system to reduce dependence on this single crop by encouraging farmers to grow other legumes. Olmantia currently grows more non-soy legumes each year than it consumes, and exports of soybeans are in decline, due to competition from suppliers in other nations.
