|
|
| | Starland County has 1 542 saline seeps which occupy a total of 2 320 ha (5 731 ac), representing 0.9% of the municipality's total area. 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.
