Other claims from this paper (8)
- Intervention effect Copper soil contamination reduced rice dry matter yield and yield attributes.
- Observation Soil enzyme activity rose to 30 DAS, then fell through harvest.
- Intervention effect Copper contamination significantly inhibited soil dehydrogenase activity at 100 to 250 mg Cu kg-1 soil.
- Intervention effect Copper contamination significantly inhibited soil urease activity at 100 to 250 mg Cu kg-1 soil.
- Intervention effect Copper contamination significantly inhibited soil acid phosphatase activity at 100 to 250 mg Cu kg-1 soil.
- Intervention effect Copper contamination significantly inhibited soil alkaline phosphatase activity at 100 to 250 mg Cu kg-1 soil.
- Observation Soil enzymes ranked dehydrogenases, urease, alkaline phosphatase, then acid phosphatase for copper sensitivity.
- Method / resource Dehydrogenases and urease were identified as better copper contamination indicators than phosphatases.
