原始语种摘要: Soil biological activity is a key component of soil health assessments, as it (a) indicates soil nutrient cycling capacity from various organic matter sources to inorganic availability, (b) relates to soil structural conditions, (c) informs about the potential to harbour biodiversity in soil and (d) often parallels changes in soil organic C and N storage in surface soils. The flush of CO2 following rewetting of dried soil represents a burst of microbial activity that can be considered an artefact, but has a strong relationship with longer-term C mineralization and basal soil respiration across a diversity of soils. This review demonstrates also the strong association of the flush of CO2 with soil microbial biomass C and net N mineralization. Weaker associations occur...
