Question 1

Which of the following best describes how the process of irrigation can lead to salinization of soils?

Accepted Answer

A)  Water associated with irrigation flows from uphill. The salts that were in the soil uphill end up being brought to the lower elevations. 
B)  Water associated with irrigation contains small amounts of dissolved salts. Evaporation leaves behind increasing concentrations of these salts. 
C)  Irrigation water contains salts. Evaporation allows the salts to be lifted away, reducing the levels of salts in the soil. 
D)  Irrigation water is treated with dissolved salts to promote plant growth. Over time the plants become saturated with salts and do not need this macronutrient. 
E)  Irrigation is primarily accomplished through the use of abundant sea water, which contains high concentrations of salts.
