A Statistical Analysis of Organic Carbon and Crop Productivity of Croplands under Long-Term Agro-Ecosystem Experiments of Tillage and Fertilization of China
Long-term field experiments play an important role in studying agro-ecological process of croplands. Samples from the experiments with historical information are helpful to researchers to assess the environmental change. In this dissertation observations from long-term fertilization and tillage experiments were used to evaluate soil organic carbon (SOC) and crop productivity dynamics of China's croplands.
Data were collected from publications reporting SOC measurements under long-term agro-ecosystem exper...
