Abstract
This study was designed to examine the reaction of microbial communities to the associated impact of inorganic fertilizers and pesticides during laboratorial simulation for 90 days. Soils were sampled from fields in three different stations of Chinese Ecosystem Research Network (CERN). The metabolic profiles were characterized by using BIOLOG GN2 microplates. The Shannon Index (H) showed that the metabolic diversity of the three types of soil exhibited similar profiles. PCA and CLUSTER further explored the variance in community structures with the same H. There were obvious changes in the structures of microbial communities during the 90-day duration of the work and the three different types of soil showedsimilar profiles for most of the period of the experiment.[PUBLICATION ABSTRACT]
