How can irrigation lead to salinization of soils?
A) Water associated with irrigation flows through the soil.
B) Water associated with irrigation contains small amounts of dissolved salts, and evaporation leaves behind increasing concentrations of these salts.
C) Wells for water are drilled too near the ocean coastlines.
D) Irrigation water is treated with dissolved salts that then lead to oversaturation.
E) Irrigation is primarily accomplished through the use of abundant seawater, which contains high concentrations of salts.

Question

Quizplus · Accepted Answer

When water associated with irrigation contains small amounts of dissolved salts, and this water is used to irrigate crops, the water seeps deep into the soil. The water evaporates very quickly in the hot climate leaving the salts behind, which accumulate over time, and this leads to salinization of the soil.
