 The M.D. has 915 line seeps which occupy a total of 11 359 ha (28 068 ac). The visibly saline areas have such high salinity levels that annual crops cannot be grown and forage crops have significantly reduced yields. Often the lands surrounding the visibly saline areas are also weakly saline, resulting in reduced yields especially for salt-sensitive crops.
