e1“Our results indicated that short-term reduced tillage (rotary-till and no-till) and residue incorporation promoted soil properties and maize growth”
e4“For both years, root characteristics of root diameter (RAD) and root surface area density (RSD), biomass indexes of root biomass (RB), shoot biomass (SB) and root-shoot ratio (R:S) were increased under these short-term treatments”

Other claims from this paper (8)
- Intervention effect Rotary-till and no-till decreased soil bulk density and compaction below the plough layer compared with plow-till in maize.
- Intervention effect Rotary-till and no-till increased soil organic carbon, total nitrogen and C:N of surface soil layers in maize fields.
- Intervention effect Residue incorporation increased soil organic carbon, total nitrogen and C:N in the 0-30 cm soil layers of maize fields.
- Intervention effect Short-term reduced tillage and residue incorporation increased root biomass, shoot biomass and root-shoot ratio in maize.
- Mechanism Structural equation modeling indicates maize yield is directly controlled by root-shoot ratio.
- Association Soil water content and C:N were positively related to maize yield.
- Association Root diameter, root surface area density and root biomass were positively related to maize yield.
- Association Shoot biomass and root-shoot ratio were positively related to maize yield.
