Ecology 94:714–724Īrtursson V, Finlay RD, Jansson JK (2006) Interactions between arbuscular mycorrhizal fungi and bacteria and their potential for stimulating plant growth. This study provides valuable information that improves our understanding on the effects of N and P input on the belowground soil microbial community and functional characteristics in plantations of different stand ages.Īllision SD, Lu Y, Weihe C, Goulden ML, Msrtiny AC, Treseder KK, Martiny JBH (2013) Microbial abundance and composition influence litter decomposition response to environmental change. Moreover, the functional differences in the soil microbiomes were identified between the 6YMP and 24YMP soil. The P addition could impact the genes involved in inorganic P-solubilization and organic P-mineralization by increasing soil AP and TP. Glyptostroboides plantation land (5 years of experimental treatment) significantly enriched microbes (e.g., Lysobacter, Luteimonas, and Rhodanobacter) involved in nitrification, denitrification, and P-starvation response regulation, which might further lead to the decreasing in alpha diversity (especially in 6YMP soil). In this study, we designed three N additions and three P levels (5 years of experimental treatment) at two Metasequoia glyptostroboides plantations of different ages (young, 6 years old middle mature, 24 years old) to understand how different addition levels of N and P affect the soil microbiome. Also, trees of different life stages have different fertilization requirements. Nitrogen (N) and phosphorus (P) have significant effects on soil microbial community diversity, composition, and function.
