The Progress of Study on Soil Organic Carbon Dynamics in Cropland |
| |
| Abstract: | Study on soil organic carbon dynamics is the key of study on soil carbon cycling. Although a rapid progess was made lately ,there are many questions needed to be solved . The advancement of factors influencing dynamics of soil organic carbon(SOC) in cropland was summarized in this paper,new technologies in the study of SOC were introduced, their advantage and disadvantage were evaluated and a use level was identified; The questions for studying the dynamics of SOC were put forword, meanwhile,and the future research directions in study were suggested. |
