What was once barren, saline-alkali land is now a sea of green and a goldmine for the dairy industry. In Shuozhou, Shanxi Province, alfalfa is helping turn problem soil into profitable farmland.

The locally grown feed is not only restoring the land, but also cutting feed costs for dairy farms both in Shanxi and far beyond. It's a striking example of how turning saline soil green can pay off in more ways than one.
