e0“Grain yields of winter wheat with biochar application showed a trend similar to soil CEC”
e1“Biochar tended to increase the soil cation exchange capacity (CEC) in the 0–20 cm soil layer and nitrate retention to 1 m soil profile, but there was no significant difference between biochar treatments and CK”

Other claims from this paper (5)
- Intervention effect Biochar had no significant effect on soil water content to 1 m depth.
- Intervention effect Biochar at 2250 kg/ha (C1) improved winter wheat grain yield by 10.3% over the control, not significantly.
- Intervention effect Biochar at 4500 kg/ha (C2) significantly improved winter wheat grain yield by 16.9% over the control.
- Intervention effect The biochar-based fertiliser treatment (CN) improved winter wheat grain yield by 15.5% over the control, not significantly.
- Mechanism The authors attribute the grain yield increases mainly to improvements in soil CEC and soil nitrate retention from biochar.
