Long-term subsoiling enhanced soil organic carbon sequestration via macropore optimization and iron-aluminum oxides enrichment

Puntos clave

• Soil organic carbon sequestration increased significantly with long-term subsoiling treatment, enhancing soil vitality.
• The study found a 25% rise in organic carbon levels over five years, showcasing effective soil management.
• Analysis of soil samples revealed that subsoiling creates optimal macropores and promotes iron-aluminum oxides enrichment.
• This suggests that improved soil management practices can lead to better carbon retention and ecosystem benefits.
