- Observation Nitrate was the main soil inorganic nitrogen form after rotation.
- Association Soil nitrate increased with increasing nitrogen fertilization.
- Intervention effect Conventional fertilization had more topsoil nitrate than optimal fertilization and control at corn harvest.
- Intervention effect Optimized fertilization reduced residual nitrate relative to conventional fertilization.
- Intervention effect Optimized fertilizer with organic fertilizer reduced residual nitrate.
- Intervention effect Optimized fertilization with straw reduced residual nitrate.
- Intervention effect Slow controlled fertilizer with organic fertilizer reduced residual nitrate.
- Intervention effect Winter wheat and summer maize yields increased slightly.
- Intervention effect Optimized fertilization increased wheat fertilizer nitrogen use efficiency by 18.94%-51.20%.
- Intervention effect Optimized fertilization improved economic and environmental benefits versus conventional fertilization.
- Intervention effect Controlled release nitrogen fertilizer improved economic and environmental benefits versus conventional fertilization.
- Recommendation The authors recommended nitrogen fertilization measures.
