Which outcome occurs when intense rainfall saturates ultisol horizons?

💡 Explanation

Intense rainfall causes nutrient depletion because leaching removes cations from the A horizon reducing fertility; soil colloids move downward via eluviation. Therefore reduced crop yields, rather than enhanced horizons, occur with leaching’s negative effects.
