Irrigation study finds local farmers efficient with water

Some people have driven by the many fields growing fresh vegetables in the Yuma Valley and wondered why there’s farming in the desert.  Or they see irrigation sprinklers watering empty fields for 24 hours a day and think it's a waste of water.  But an ongoing irrigation and salinity project has recently found that the irrigation techniques used by local farmers exceed 90 percent efficiency.  That means hardly any water is being wasted in growing vegetables -- even it the desert.
