Which consequence results when excessive irrigation accelerates eluviation in semi-arid farmland?

💡 Explanation

Decreased cation exchange capacity occurs because excessive irrigation leads to increased leaching, a form of eluviation, where cations essential for soil fertility are stripped from the soil profile. Therefore, reduced cation exchange results, rather than the water table rising substantially because aquifers are relatively deep.
