Which outcome accelerates subsidence in agricultural karst regions?

💡 Explanation

Increased nitrogen fertilizer use leads to runoff, causing acid soil conditions driving dissolution of limestone bedrock through acidification, which initiates sinkhole formation on the surface; therefore increased sinkholes, rather than changes in recharge, occur.
