- Intervention effect Straw return improved soil structure more than potassium fertilizer.
- Intervention effect Straw return improved maize root growth more than potassium fertilizer.
- Intervention effect The interaction of straw return and potassium application was better than either alone.
- Intervention effect Straw return improved potassium fertilizer effects on soil bulk density by 3.99%–7.27%.
- Intervention effect Straw return improved potassium fertilizer effects on soil porosity by 3.89%–7.40%.
- Intervention effect Straw return improved potassium fertilizer effects on spring maize root length by 1.35%–71.01%.
- Intervention effect Straw return improved potassium fertilizer effects on maize root surface area by 19.16%–42.45%.
- Intervention effect Straw return improved potassium fertilizer effects on maize root volume by 10.49%–22.73%.
- Intervention effect Straw return improved potassium fertilizer effects on maize grain K-absorption efficiency by 13.57%–19.67%.
- Intervention effect Straw return improved potassium fertilizer effects on maize yield by 4.43%–7.05%.
- Recommendation Combined straw return and potassium fertilizer was recommended as the best measure for stable high maize yield, K-absorption efficiency and nutrient management.
