| Description: High salinity in agricultural fields has been a problem since the beginning of cultivation practices, since the evaporation of irrigated water of poor quality leaves behind salt solutes which accumulate in the soil over time. While irrigation has made it possible to extend agriculture to semi-arid and arid areas of land, and has been partly responsible for the large increases in food production of the last 40 years, it has also resulted in large-scale water lodging and salinity. |
