Other claims from this paper (8)
- Intervention effect Subsoiling increased microbial biomass carbon in the 20–40 cm soil layer relative to rotary tillage.
- Intervention effect Subsoiling increased soil respiration rate relative to rotary tillage.
- Intervention effect Subsoiling increased summer maize grain yield, particularly with S35.
- Intervention effect S35 raised grain yield by 8.30% in 2018.
- Intervention effect S35 raised grain yield by 13.89% in 2019.
- Intervention effect Carbon emission efficiency was significantly higher under S35 than S40.
- Recommendation The authors identify S35 as the best treatment for summer maize yield and carbon emission efficiency.
- Recommendation The authors recommend applying and promoting S35 in the North China Plain.
