Effects of tree mycorrhizal type on soil respiration and carbon stock via fine root biomass and litter dynamic in tropical plantations

Abstract Tropical forests are among the most productive and vulnerable ecosystems in planet. Several global forestation programs aiming to plant millions of trees tropical regions future decade. Mycorrhizal associations known largely influence forest soil carbon (C) stocks. However, date, little is on whether how different tree mycorrhizal types affect respiration (Rs) C stocks forests. In this study, we used a three-decade common garden experiment, with three arbuscular (AM) ectomycorrhizal (EM) monocultures, investigate impacts type Rs Associating biotic (e.g. root biomass, litter dynamic, microbes) abiotic factors microclimate) were also measured. Our results showed that AM stands supported significantly higher stock, turnover rate fine biomass than EM stands. Further statistical analysis displayed was important factor regulating stock compared other or factors. Moreover, found directly indirectly affected via i.e. production, standing crop rate. findings highlight effects cycle, suggesting planting species could contribute promotion ecosystems.
