Summary

This 12-year field study in temperate plantations investigates how sustained nitrogen addition alters soil microbial communities and their capacity to decompose organic carbon. The authors suggest that long-term nitrogen enrichment restructures microbial assemblages in ways that enhance carbon mineralisation, as mediated by changes in community composition. The findings contribute to understanding of how anthropogenic nitrogen affects soil carbon cycling dynamics in plantation ecosystems.

UK applicability

Findings from temperate plantation systems may be relevant to UK forestry and agroforestry practices, particularly where nitrogen deposition or fertiliser application is a management concern. However, direct applicability depends on matching soil type, tree species, and climate context to UK conditions.

Key measures

Soil organic carbon decomposition rates, microbial community composition (likely via molecular profiling such as 16S rRNA gene sequencing), soil nitrogen levels, microbial functional groups

Outcomes reported

The study examined how 12 years of nitrogen addition affects soil organic carbon decomposition rates and shifts in microbial community composition in temperate plantation systems. It measured changes in microbial taxa and their functional roles in mediating carbon cycling under elevated nitrogen conditions.
