Litter decomposition is a key component of biogeochemical recycling. It is highly sensitive to changes in microbial community assembly. An interesting phenomenon in litter decomposition is the home-field advantage (HFA), where litter decomposes faster in native locations than in foreign sites. However, the role of the HFA in litter decomposition remains controversial. This review examines current evidence relating to the HFA using the leaf economics spectrum theory and the Lotka-Volterra niche competition model and explains its influence on the microbial assembly process. Here, it is proposed that the microbial community assembly could help to explain the HFA at spatiotemporal scales. This review improves understanding of the role of the succession of microbial communities in HFA litter decomposition and in the elemental cycle of forest systems.
