| Abstract: | The CO2 release,SMBC and WSOC content in red soil samples respectively applied with organic fertilizer,chemical fertilizer,chemical + organic fertilizer were analyzed during their incubation period to study the effects of different fertilizers on organic carbon mineralization and carbon morphology in red soil.The results showed that the CO2 release rate of different treatments was high in the early incubation period and basically stable after 10d,there was very significant difference in CO2 release among di... |
