| Outline of Final Research Achievements |
Soil respiration consists of CO2 fluxes from free-living microbes, plant roots, and mycorrhizal fungi. Understanding the spatio-temporal pattern of CO2 fluxes from the three components can contribute to better understanding of soil organic matter dynamics, and in turn, prediction of global carbon dynamics. Many studies have measured root respiration and soil microbial respiration. However, mycorrhizal fungal respiration has been rarely measured, largely due to the lack of appropriate measuring method.
Here we developed a measuring method for ecto-mycorrhizal fungal respiration by using micro-pore mesh in-growth core. We first, in the field, examined the effects of host plants and soil nutrient availability on ecto-mycorrhizal fungal respiration.
