Other claims from this paper (12)
- Observation Nitrogen- and phosphorus-treated oil palm trunk and empty fruit bunch composts had good stability and higher quality than other composts.
- Observation The selected oil palm composts had the lowest C/N ratios, at 14-18.
- Observation Their pH values were comparatively low, at 4.6-6.4.
- Observation Their total N was 0.95-1.84%.
- Observation Nitrate exceeded ammonium nitrogen in those composts.
- Observation Their specific respiration rates were very low, at 0.25-0.63.
- Observation The plant growth test supported the microbiological-test conclusions.
- Method / resource The applied nitrogen mineralization index could not serve as a stability index for every compost type.
- Observation Commercial composts had very low total and mineral nitrogen compared with oil palm residue composts.
- Recommendation The authors considered commercial composts low in nutritional value and unsuitable for planting media.
- Recommendation The authors considered the selected oil palm composts suitable for planting media.
- Recommendation The authors proposed bunch ash addition to further improve compost quality.
