Other claims from this paper (8)
- Observation Ecosystem carbon density of Sonneratia apetala was highest in the oldest stand (44 years), at 461 t ha -1.
- Observation Soil organic carbon density of Sonneratia apetala showed a unimodal pattern with stand age, peaking at 195 t ha -1 in the 26-year-old stand.
- Observation The vegetation carbon density increase rate of Sonneratia apetala was greatest (13.17 t ha -1 yr -1) in the 18-year-old stand.
- Observation The soil organic carbon accumulation rate of Sonneratia apetala (6.39 17 t ha -1 yr -1) peaked in the 26-year-old stand.
- Observation The ecosystem carbon accumulation rate of Sonneratia apetala (19.79 t ha -1 yr -1) peaked in the 26-year-old stand.
- Mechanism The initial rise in soil organic carbon density of Sonneratia apetala plantations reflects high litter and root activity in middle-aged stands.
- Mechanism The later decline in soil organic carbon density is likely due to greater belowground carbon allocation to lower soil horizons in older stands with deep roots.
- Recommendation The authors recommend more widespread afforestation with Sonneratia apetala to enhance carbon storage.
