Other claims from this paper (5)
- Intervention effect Soil penetration resistance increase reduced the average number of sugarcane roots by 45%.
- Intervention effect Compaction reduced sugarcane root volume, surface area and length.
- Intervention effect Mechanical stress weakly impacted coarse sugarcane roots (1–2 mm diameter).
- Intervention effect Fine sugarcane roots (0.5–1 mm diameter) were more growth limited in compacted soils.
- Association Sugarcane root elongation rate was modelled as a function of mechanical and water stress.
