None of these answers
- 3.Which of the following best describes how the process of irrigation can lead to salinization of soils?
- A.
Water associated with irrigation flows 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 is treated with dissolve salts to promote plant growth. Over time the plants become saturated with salts and do not need this macronutrient.
- D.
Irrigation is primarily accomplished through the use of abundant sea watre, which contains high concentrations of salts
