Which outcome commonly resulted from irrigating Mesopotamian farmland relying solely on Tigris and Euphrates river floods?

💡 Explanation

The repeated flooding and subsequent evaporation of water leads to increased soil salinity because dissolved salts are deposited in the soil, accumulating over time due to capillary action. Therefore, soil became less fertile, rather than rich with nutrients or promoting optimal growth.
