Repeated application of irrigated water in dry climates leads to...

• a drop in productivity of the land by more than 10%, leading to desertification
• a build up of nutrients, leading to increased levels of erosion
• a build up of salts in the soil, leading to salinization
• decreased phosphorus and nitrogen, leading to eutrophication
