Description :
In this study, the effects of N addition and vegetation removal after one growing season on soil properties were examined in a Calamagrostis angustifolia freshwater marsh at the Sangjiang Marsh Wetland Experimental Station in the Heilongjiang Province, Northeast China. It is showed that short-term nitrogen addition does not significantly affect soil dissolved organic C (DOC) pool in marshland; Nitrogen addition can affect the soil biochemical process indirectly through vegetation. It is concluded that nitrogen addition and vegetation removal significantly increased soil microbial biomass C (MBC) pool.
