Detailed explanation-1: -Water table rise due to salinization reduces the earth’s ability for water infiltration. With heavy rainfalls or river flooding, soils cannot cope with high amounts of water flows. Thus, insufficient absorption results in runoffs and floods.

Detailed explanation-2: -“Irrigation inevitably leads to the salinization of soils and waters. … In many countries irrigated agriculture has caused environmental disturbances such as waterlogging, salinization, and depletion and pollution of water supplies.

Detailed explanation-3: -Salinity affects production in crops, pastures and trees by interfering with nitrogen uptake, reducing growth and stopping plant reproduction. Some ions (particularly chloride) are toxic to plants and as the concentration of these ions increases, the plant is poisoned and dies.

Detailed explanation-4: -Salinity along with drought is one of the leading abiotic stresses in agriculture which foster growth retardation, physiological abnormalities, and lower production output of field crops throughout the world. Salt stress remains a major growth-limitation factor mostly in arid and semiarid zones.
