Salty soil is a growing threat to crops worldwide. Hotter, drier weather has increased evaporation rates, drawing moisture from the soil and leaving behind concentrated mineral salts. At the same time, water shortages are forcing farmers to irrigate using water from lower-quality
Salty soil is a growing threat to crops worldwide. Hotter, drier weather has increased evaporation rates, drawing moisture from the soil and leaving behind concentrated mineral salts. At the same time, water shortages are forcing farmers to irrigate using water from lower-quality, saline or recycled sources.
Scientists estimate that around half of the world's irrigated farmland is now affected by salinity to some degree.
