Why are soybeans important to agriculture in Anhui province?

Soybeans are a significant agricultural product in Anhui province, which ranks as one of China’s most important producers of the crop.1

Their importance to the region's agricultural system is primarily defined by their role in crop rotation: soybeans are grown mainly in the northern part of the province, where they are cultivated in rotation with wheat or barley. This practice helps maximize the productivity of the land, as most of the province's agricultural area is utilized to produce two crops per year.1
