Söderfjärdens draining in the 1920s gave the area significantly expanded cultivation. A demand for hay in large quantities for the cattle-dominated agriculture arose. Thus, came Söderfjärden to be a kingdom of barns. At most, there were 3 000 hay barns in the 1940s and 1950s.
Söderfjärden's cultivated area is about 2 300 ha. Today cereals are grown on about 80% of the area. Barley is the dominant legume, but also wheat and oats are grown. Sugar beet, oilseeds and potato are other growing plants.
Pumps in the pump house drain continuing 2/3 of the crop land. Söderfjärden's crop land is a Natura 2000 site, meaning the crop land is a protected nature/cultur area. Söderfjärden and parts of near by villages Sundom, Munsmo and Solf provides a nationally valuable landscaping area.
