Which pedogenesis process decreases topsoil fertility with intense rainfall?

💡 Explanation

Leaching removes soluble nutrients like nitrogen, potassium, and phosphorus from topsoil because water transports them downwards, therefore reducing fertility. This occurs rather than capillary action which draws minerals upwards or bioturbation which mixes material.
