Based on a 18-year-long experiment conducting at Baiyun experiment station in Wuwei City
theeffects of long-term fertilization on soil organic
inorganic and microbial biomass carbon in 0-20cm layer ofirrigated desert soil were analyzed.The results showed that long-term combined application of nitrogen andorganic fertilizer
as well as manure application led to increases of soil organic and microbial biomass carboncontents
but had no significant impacts on inorganic and microbial biomass carbon levels.Long-term application of nitrogen fertilizer had no significant influence on soil organic
inorganic and microbial biomass carbon contents.All results revealed that soil organic carbon contents negatively correlated with inorganic carbon contents
and positively with soil microbial biomass carbon contents.
