Irrigation
Irrigation inevitably leads to the salinization of soils and waters. In the United States yield reductions due to salinity occur on an estimated 30% of all irrigated land. World wide, crop production is limited by the effects of salinity on about 50% of the irrigated land area. In many countries irrigated agriculture has caused environmental disturbances such as waterlogging, salinization, and depletion and pollution of water supplies. Concern is mounting about the sustainability of irrigated agriculture.

Salinity
Saline and  alkali  soil  conditions  reduce  the  value  and  productivity  of  considerable  areas  of  land  in  the  United States. The problem  is  an  old  one,  and  there  is  much  information  on  this  subject  in  the  technical  literature. Many crop  failures  result  from  growing  crops  that have  low  salt  tolerance. Alfalfa, barley,  sugar  beets, and  cotton  are  tolerant  crops  that  can  often  be  grown where  salinity  is  a  problem.

Salt Farm
A farm on the island of Texel, The Netherlands, is testing the salt tolerance of crops. . An example of results is shown in the figure below. The figure is based on a figure in the report. The soil salinity is expressed in electric conductivity (ECe). The Maas-Hoffman model is used. Envelope lines (yellow) and error ranges (brown) have been added.
