Intervention effect The tillage treatment difference was smaller in the cotton year.
Intervention effect Treatments influenced macroaggregate stability in the scarification year.
Recommendation The authors recommend ploughing every second year with compost and mineral fertilizer instead of annual ploughing with mineral fertilizer.

Title

Evaluating the impact of long‐term tillage practices on crop yield, soil properties, and greenhouse gas emissions in western Nebraska

Sujani De Silva; Christine Booth; Deepak Ghimire; et al. Soil Science Society of America Journal 2026. doi:10.1002/saj2.70273

Other claims from this paper (7)

Intervention effect Strip-tillage gave higher two-year mean maize yield than no-tillage.
Intervention effect Moldboard plow gave higher two-year mean maize yield than no-tillage.
Intervention effect No-tillage and strip-tillage improved soil organic matter, organic carbon and microbial activity relative to moldboard plow.
Intervention effect Macroaggregate stability (>250 µm) was greater under no-tillage and strip-tillage.
Association Mean CO2 emissions did not differ among tillage systems.
Intervention effect N2O emissions were higher under no-tillage and strip-tillage than under moldboard plow.
Recommendation Strip-tillage is recommended because it gives the benefit of localized tillage along crop rows while preserving no-tillage conditions between rows.
