Physicochemical properties of soils from three different land use habitat types in the Sanjiang Wetland, northeastern China.
| Land use type | pH | Total organic carbon (g/kg) | Total nitrogen (g/kg) | Available nitrogen (mg/kg) | Total phosphorus (mg/kg) | Available phosphorus (mg/kg) | Soil gravimetric moisture (%) |
|---|---|---|---|---|---|---|---|
| Wetland | 5.5 ± 0.0c | 52.7 ± 1.3a | 4.3 ± 0.8a | 455.3 ± 29.6a | 6.4 ± 1.2a | 26.3 ± 1.8a | 52.8 ± 1.0a |
| Arable land | 5.8 ± 0.1b | 25.6 ± 1.4b | 3.1 ± 0.6b | 197.6 ± 7.5b | 3.7 ± 0.7b | 26.7 ± 3.6a | 32.9 ± 3.1c |
| Forest | 7.4 ± 0.1a | 25.1 ± 1.5b | 1.8 ± 0.3c | 143.8 ± 7.2c | 3.2 ± 0.5b | 32.7 ± 4.5a | 47.0 ± 1.2b |
Note: Statistically significant differences (P < 0.05; n = 3) between habitats is indicated by different superscript letters a–c in the same column.
