Other claims from this paper (12)
- Intervention effect The 25% CS addition did not negatively affect root or shoot traits.
- Intervention effect The 25% CS addition improved flowering earliness.
- Observation At 50% CS, Buddleja showed moderate tolerance.
- Observation At 50% CS, Lythrum performed poorly.
- Observation At 50% CS, Veronica performed poorly.
- Intervention effect The substrate with 75% CS addition significantly reduced rooting and growth in all three species.
- Intervention effect High-CS substrates had elevated pH and electrical conductivity.
- Mechanism The authors suggest that elevated pH and electrical conductivity in high-CS substrates likely contributed to plant stress.
- Observation Physiological indicators confirmed minimal stress at 25% CS.
- Observation Physiological indicators showed increased stress response at 75% CS.
- Recommendation The authors conclude that coffee silverskin can replace up to 25% of peat in substrates without compromising plant performance.
- Recommendation The authors state that higher CS levels require structural or chemical adjustments to reduce compaction and stress effects.
