Forest management causes soil carbon loss by reducing particulate organic carbon in Guangxi, Southern China

The loss of soil organic carbon (SOC) following conversion natural forests to managed plantations has been widely reported. However, how different SOC fractions and microbial necromass C (MNC) respond forest management practices remains unclear. We sampled 0–10 ​cm mineral from three one protected in Guangxi, Southern China, explore affect through changing mineral-associated (MAOC) particulate (POC), as well fungal bacterial C. Compared with the forest, POC abandoned, mixed Eucalyptus significantly decreased, but MAOC showed no significant change, indicating that was mainly decreased under management. Forest also reduced root biomass, extractable C, MNC, total biomass (measured by phospholipid fatty acid), increased fungi-to-bacteria ratio (F:B) peroxidase activity. Moreover, positively correlated negatively F:B These results suggested input properties together regulated dynamics during Overall, this study indicates intervention decreases reducing suggests protection can help sequester more ecosystems.

Increasing plant species diversity stimulates soil microbial necromass nitrogen accumulation in a subtropical forest

Abstract Soil nitrogen status is tightly related to vegetation productivity and ecosystem carbon sequestration. Therefore, how increasing plant species diversity (PSD) during restoration or afforestation affects soil pool would ultimately determine its effects on Though diversifying has been found benefit accumulation, it influences microbial necromass (MNN), which a major constituent of pool, remains unexplored. Forty‐five plots with different PSD were selected in subtropical forest the being calcareous. MNN was indexed by amino sugars growth, use efficiency, other biotic abiotic variables simultaneously measured explore influence pool. Increasing significantly ( p < 0.05) stimulated growth contents fungal, bacterial, total MNN, but only marginally = 0.07) enhanced efficiency. Structural equation modelling revealed that PSD‐stimulated content enhancing biomass through three paths, is, promoting via availability relative abundance copiotrophic taxa, inputs plant‐derived available substrates, improving mineral protection elevating exchangeable calcium magnesium levels. However, did not alter contribution likely owing proportional increase organic marginal Synthesis applications : These findings highlight an effective measure for accumulation. Considering importance supporting sequestration, current study advocates incorporation afforestation.
