Changes in the soil organic carbon balance on China’s cropland during the last two decades of the 20th century

Abstract Agro-ecosystems play an important role in regulating global changes caused by greenhouse gas emissions. Restoration of soil organic carbon (SOC) in agricultural soils can not only improve soil quality but also influence climate change and agronomic productivity. With about half of its land...
