Which consequence results when extended irrigation using qanats introduces salts?

💡 Explanation

Salinization concentrates dissolved salts via capillary action, leading to osmotic stress because the plant's water uptake is inhibited; therefore, crop yields decrease over the long term, rather than improvements from aggregation or nitrogen, which are unrelated.
