  Researchers Reveal Distinct Soil Carbon Sequestration Patterns and Saturation Levels Across Climate Zones in Eastern China

  The capacity of agricultural soils to store organic carbon and the point at which they become saturated remain critical unknowns in global carbon cycle. Understanding both the current saturation levels and future sequestration potential of soil organic carbon (SOC) is essential for developing targeted strategies to enlarge the soil carbon pool and mitigate climate change—yet how climate and land-use practices jointly shape these parameters across large geographic scales has remained poorly understood.
