Cropping System Conversion led to Organic Carbon Change in China’s Mollisols Regions

Abstract Land use change driven by diet, globalization, and technology advancement have greatly influenced agricultural production and environment in the mollisols region of China, with a marked impact on the depletion of soil organic matter, a signature property of mollisols. Here we report finding...
