← GeographyWhich outcome reduces nutrient availability during later-stage pedogenesis?
A)Formation of insoluble secondary minerals✓
B)Rapid decomposition of detrital bedrock
C)Increased capillary action within pores
D)Enhanced surface aggregation by microbes
💡 Explanation
In advanced pedogenesis, stable minerals form during weathering, thus reducing mineral dissolution; mineral precipitation causes immobilization of once mobile nutrients because they are now chemically bound, rather than unbound. Therefore, insoluble mineral neoformation reduces long-term nutrient availability rather than releasing them.
