- Observation Caragana korshinskii gave the greatest root-soil shear strength increase, 60%, at natural moisture.
- Observation Astragalus adsurgens increased root-soil shear strength by 49% at natural moisture.
- Observation Astragalus adsurgens had the highest cohesion increase, 46%.
- Observation Hippophae rhamnoides had the lowest cohesion increase, 28%.
- Association Root-soil shear strength initially rose and then declined with increasing moisture.
- Association Root-soil cohesion initially rose and then declined with increasing moisture.
- Observation Optimal moisture was 7.5% for Caragana korshinskii.
- Observation Optimal moisture was 11.5% for Hippophae rhamnoides.
- Observation Optimal moisture was 7.5–11.5% for Medicago sativa.
- Observation Optimal moisture was 11.5% for Hedysarum fruticosum.
- Observation Optimal moisture was 7.5–11.5% for Astragalus adsurgens.
- Observation Root-soil internal friction angle declined by –1% to –25% against the control.
- Mechanism The authors concluded cohesion was the main contributor to increased shear strength.
- Observation Root-induced soil consolidation was pronounced under 12.5 kPa loading.
- Observation Root-induced consolidation diminished under 25 kPa, possibly because deeper roots were sparse.
- Intervention effect Mixed-species planting improved surface soil stability more than single-species stands.
