Which process reduces soil profile development if organic matter decomposition slows significantly?

💡 Explanation

Slower decomposition limits the formation of humic substances necessary for pedogenesis, which restricts horizon differentiation because fewer distinct soil layers develop in the soil profile; therefore A, rather than enhancements to profile development.
