Which outcome occurs when intensive agriculture disrupts pedogenesis of Oxisols?

💡 Explanation

Reduced organic matter stability results because tillage accelerates decomposition via oxidation; this reduces soil carbon, a key binding agent that protects organic matter. Therefore, topsoil erodes quickly, rather than enhanced aggregation occurring because reduced soil organic structure reduces habitat for soil microbiota.
