Other claims from this paper (10)
- Intervention effect Sediment gave higher sudangrass yield than soil at the first cutting.
- Intervention effect Two percent scrubber sludge produced the highest average yield across soil and sediment combinations.
- Observation Eight percent scrubber sludge adversely affected plant size and color.
- Intervention effect At the second and third cuttings, soil with 8% scrubber sludge gave the highest yields.
- Intervention effect Sediment with 8% scrubber sludge continued to have lower yields than other treatments.
- Intervention effect Soil alone outyielded sediment alone at the second and third cuttings.
- Observation Total weight across three cuttings suggested sediment was better than soil for sudangrass growth.
- Observation Mixing soil with sediments offered little yield advantage.
- Intervention effect Scrubber sludge increased sudangrass yield in soil-rich combinations.
- Observation Scrubber sludge had little effect on yield in sediment-rich combinations.
