Abstract
In a situ buried-bag experiment, the seasonal dynamics of soil total organic carbon (TOC) and labile organic carbon in soil amended with maize stalk (MS), chicken manure (CM), pig manure (PM) and mixture of them (MI) were studied in one year. MS with a low N content and high C/N ratio decomposed a little faster than other materials with low C/N ratios. Labile carbon pool – microbial biomass carbon (MBC) and light fraction of organic carbon (LFOC) exhibited an absolute difference in the 365-day incubation period: MS in MBC showed a gentle ascendant tendency; however, CM and PM displayed a rapid decrease. The concentrations of LFOC in all the treatments decreased coincidently nevertheless. MBC was more sensitive to organic material addition than other labile pools, despite of its low level.
