e0“Similar soil properties were observed between ST-BR and NT, which showed they had a significantly greater BD, >0.25 mm water stable aggregate content (WR0.25) (especially in the amount of >2 mm and 1–2 mm size proportion), aggregate stability, and SOC than ST-IR and CT-IR at a depth of 0–20 cm”

Other claims from this paper (10)
- Intervention effect ST-BR and NT had significantly greater aggregate stability than ST-IR and CT-IR at 0–20 cm depth.
- Intervention effect ST-BR and NT had significantly greater soil organic carbon than ST-IR and CT-IR at 0–20 cm depth.
- Intervention effect ST-IR increased soil temperature above NT by 1.64 °C.
- Intervention effect CT-IR increased soil temperature above NT by 1.80 °C.
- Intervention effect ST-IR had slightly greater soil moisture than CT-IR in the top 10 cm layer during seed emergence.
- Intervention effect Maize seed emergence was later under no tillage than under ST-IR and CT-IR.
- Intervention effect The average annual maize yields in strip tillage were slightly greater than under NT and CT, but the differences were not significant.
- Intervention effect CT-BR had a poor soil structure compared with other treatments at 0–30 cm depth.
- Intervention effect CT-BR had lower soil organic carbon than other treatments at 0–30 cm depth.
- Recommendation Strip tillage should be applied in the Mollisols region of Northeast China to improve soil water-heat conditions and maize yield.
