Abstract
Aims
The combined effects of nitrogen (N) deposition and management practices on fine root decomposition remain unknown. The objective of this study was to investigate the effects of the two factors on fine root decay in Moso bamboo plantations.
Methods
This study was performed over a three-year period and included three nitrogen treatments (30, 60, and 90 kg N ha−1 yr.−1) and two management practices (conventional and intensive).
Results
Fine root decomposition was significantly affected by N inputs and management practices both separately and in combination (P < 0.01). N inputs had a stronger effect than management practices. The low-N input (30 kg N ha−1 yr.−1) accelerated fine root decomposition and nutrient release, whereas high-N inputs (≥ 60 kg N ha−1 yr.−1) inhibited decomposition and nutrient release. Moreover, intensive management practices strengthened the inhibitory effects of the high-N inputs.
Conclusions
Moderate N deposition (< 60 kg N ha−1 yr.−1) may decrease soil carbon storage but increase Moso bamboo productivity, while excessive N deposition (≥ 90 kg N ha−1 yr.−1) may have opposing effects. The combined effects of management practices and nitrogen amendment should be considered when estimating the effects of increasing atmospheric N deposition on plantation ecosystems.
