caption_attribution_description: English: Yield of wheat versus soil salinity (ECe, dS/m) measured in farmers' fields in the Nile Delta, Egypt
context_page_description: Salt tolerance of crops is the maximum salt level a crop tolerates without losing its productivity while it is affected negatively at higher levels. The salt level is often taken as the soil salinity or the salinity of the irrigation water.
  Salt tolerance is of importance in irrigated lands in arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. A regional distribution of the 3,230,000 km² of saline land worldwide is shown in salt affected area based on the FAO/UNESCO Soil Map of the World.
  Additionally, in areas where sprinkler irrigation is practiced, salty sprinkler water can cause considerable damage by leaf burning, whether the soil is saline or not.

  Salt tolerance is of importance in irrigated lands in (semi)arid regions where the soil salinity problem can be extensive as a result of the salinization occurring here. It concerns hundreds of millions of hectares. A regional distribution of the 3,230,000 km² of saline land worldwide is shown in salt affected area based on the FAO/UNESCO Soil Map of the World.

caption: The irrigated wheat crop in Egypt has a salt tolerance of ECe=7.6 dS/m beyond which the yield declines. The data were collected in farmers' fields.[1]
