Which consequence occurs when Mesopotamian irrigation canals excessively saturate surrounding soil over time?

💡 Explanation

When canals oversaturate soil, capillary action draws groundwater upwards, depositing dissolved salts on the surface through evaporation; this salinization reduces soil fertility. Therefore, salt accumulation degrades fertility, rather than improving drainage or crop yields, which require different hydrological conditions.
