Other claims from this paper (12)
- Intervention effect Chemical N fertilizer increased silage yield, dry matter yield, plant height and total N uptake relative to control.
- Intervention effect The specified N and sludge rates produced almost the same silage and dry matter yields.
- Intervention effect N fertilizer increased sorghum leaf N, P, Ca, Mg, Fe and Mn content.
- Intervention effect Sewage sludge increased sorghum leaf N, P, Ca, Mg, Fe and Mn content.
- Intervention effect The specified N and sludge rates gave similar leaf nutrient contents.
- Intervention effect Neither treatment affected sorghum leaf potassium content.
- Intervention effect N fertilizer increased leaf Zn content.
- Intervention effect Sewage sludge increased leaf Zn content, with the highest level at 23.80 Mg ha(-1).
- Intervention effect Sewage sludge increased leaf Cu content.
- Intervention effect Sewage sludge increased soil Fe, Zn, Cu and Ni contents, highest at 23.80 Mg ha(-1).
- Observation No measured heavy metal reached a toxic level in plant or soil.
- Recommendation The authors concluded Van sewage sludge could be used as a sorghum nitrogen source without toxic heavy metal risk.
