Effects of Soil Water Content on Soil Microbial Biomass and Community Structure Based on Phospholipid Fatty Acid Analysis

摘要：

Three different kinds of soils collected from Heilongjiang, Jiangsu and Guangxi province of China were used to test the effects of different water contents on soil microbial biomass and community structure. Soils were moistened to 40%, 60% and 80% of water holding capacity (WHC) first. Then the moist soils were incubated in the dark room at 25℃ for 56 days. Phospholipd fatty acid (PLFA) analysis were carried on days 0, 3, 7, 14, 28 and 56 to track the changes of soil microbial organisms. The results showed that soil microbial biomass and community structure based on PLFA analysis did not response to the different soil water contents. soil microbial organisms might get used to a wide range of soil water contents.
