Abstract

Abstract:

The limitation of carbon availability on microbial respirat ion was studied in the Calamagrostisangustifolia soil in Sanjiang Plain. The results suggest that carbon availability limits the microbialrespirat ion in root layer soil and subsoil initially, whereas it does not limit the microbial respiration after115 h incubation for recovery from the disturbance in physical, chemical and biological structure causedby sampling from the field, then after 5 h incubation when the labile carbon has been mineralized theavailable carbon limits the microbial respiration again. At the same time the results show that the soilorganic matter affects carbon availability index significantly when its value is lower than 10%, but theeffect is little when the soil organic matter is higher than 10%. The microbial biomass carbon is linearlycorrelated with carbon availability in the Calamagrostis angustifolia soil.

Key words: microbial respirat ion, microbial biomass carbon, soil organic matter, Calamagrostisangustifolia, Sanjiang Plain
