e2“Hence, RT presented higher corn yield compared to NT, even if the water content remained lower”
e3“we used a long-term field experiment located at the Dryland Farming Experimental Station in Shouyang, Shanxi Province, in northern China”
e5“In addition, bulk density, porosity, S index, and mean weight diameter showed irregular and different relationships with grain yield during the growth period, especially there were no significant relationships between these soil physical properties and grain yield (P > 0.05)”
Title

Other claims from this paper (14)
- Intervention effect Reduced tillage with residue incorporation (RT) gave higher corn yield than no-tillage with residue mulching (NT).
- Intervention effect Tillage management, soil depth and growth period significantly influenced soil physical properties (P < 0.05).
- Intervention effect No-tillage (NT) significantly increased the lower limit of least limiting water range (LLWR), which made root water uptake more difficult.
- Intervention effect RT and NT treatments increased the porosity of pores 55-165 μm in diameter.
- Recommendation RT treatment is the most effective tillage practice compared with CT and NT treatments from the perspective of grain yield.
- Mechanism Grain yield under RT was highest by increasing water sorptivity, LLWR and WUE.
- Association Soil water sorptivity had a significant influence on grain yield.
- Association Water repellency index had no direct effect on grain yield.
- Association Water sorptivity was the most favorable for grain yield improvement compared with soil organic carbon, mean weight diameter, penetration resistance and total porosity.
- Association Microbial biomass carbon had a closer relationship with the water repellency index than soil organic carbon did.
- Intervention effect Soil organic carbon and microbial biomass carbon were higher in RT and NT treatments than in CT treatment.
- Association Maize yield was mainly driven by a lower limit of LLWR and penetration resistance.
- Association Both water sorptivity and water repellency index had effects on soil water availability.
- Association The effect of soil water repellency on soil water content became more obvious as soil moisture decreased after rainfall.
