- Intervention effect Replacing plowing with flat-cut loosening decreased mean yield across 15 crops by 9.0%.
- Intervention effect In the authors’ experiment, spring crop mean yield also fell by 9.0%.
- Intervention effect Across 15 experiments, arable-layer soil density changed by only 0.7%.
- Intervention effect Across 15 experiments, agronomically valuable soil structure content changed by only 0.1%.
- Intervention effect In the authors’ experiment, soil density improved by 2.1%.
- Intervention effect In the authors’ experiment, soil structure improved by 1.4%.
- Intervention effect Flat-cut tillage decreased total arable-layer soil permeability by 1.9%, while it stayed acceptable.
- Intervention effect Five of 15 publications reported lower root-layer available moisture after non-moldboard loosening.
- Intervention effect The remaining 10 publications reported unchanged or increased available moisture.
- Intervention effect Available soil moisture under flat-cut loosening was 1.7% higher than under plowing.
- Intervention effect At mid-season, flat-cut cultivation gave a 6.1% advantage in available moisture.
- Intervention effect At season end, flat-cut cultivation gave a 6.4% advantage in available moisture.
- Intervention effect Crops had 27–31% higher weed infestation after moldboard-free autumn tillage.
