Which outcome occurs when intensive agriculture reduces bioturbation?

💡 Explanation

Declining aggregates results from depleted aggregate formation ability. Bioturbation directly contributes to soil structure; reduced bioturbation lowers structure through activity rather than improving porosity because the absence of living organisms fails to mechanically bind soil, therefore the aggregate strength diminishes instead.
