Which downstream soil effect mainly results from prolonged agricultural irrigation in arid climates?

💡 Explanation

Increased surface salt concentration arises because capillary action causes dissolved salts to move upwards as water evaporates, a mechanism called salinization; therefore surface salt increases occur, rather than increased organic matter because minerals are leached from the deep layers.
