👁 1 viewsSalinization of farmland from irrigation is worst when there is high evaporation and little rainfall. Dry, hot, and windy conditions accelerate evaporation from the soil surface, causing salts to accumulate as irrigation water evaporates and leaching is limited. In such climates, salts remain near the root zone, harming crops. The other options have less evaporation or more rainfall, which helps leach salts away or dilute them; hence they are less prone to severe salinization compared with dry, hot, and windy conditions.
In arid and semi-arid regions, soil salinity often increases due to high evapotranspiration surpassing precipitation and inadequate drainage.
Salinization is most severe when evaporation is high and leaching is minimal (dry, hot, windy climates).
