- Intervention effect In sandy loam soils, higher biochar rates combined with urea enhanced wheat grain yield.
- Association In sandy loam soils, higher biochar rates combined with urea were associated with increased sub-root-zone NO3-N values in wheat.
- Intervention effect In silty clay loam soils, moderate biochar application (about 40 t ha-1) combined with ammonium nitrate improved nitrogen use efficiency.
- Intervention effect In silty clay loam soils, moderate biochar application (about 40 t ha-1) combined with ammonium nitrate limited downward nitrogen redistribution.
- Association Grain yield of wheat was strongly correlated with dry matter accumulation (r = 0.93).
- Method / resource APSIM-Wheat and HYDRUS-2D reproduced wheat crop growth dynamics across soil textures.
- Method / resource The simulations overestimated downward nitrogen redistribution at low biochar rates compared with higher rates.
- Method / resource The simulations underestimated downward nitrogen redistribution at higher biochar rates compared with low rates.
- Mechanism The simulation discrepancies likely reflect structural limitations in representing time-dependent biochar effects, dynamic sorption processes and microbially mediated nitrogen transformations.
- Recommendation Soil-specific integration of biochar rate and nitrogen fertilizer source is recommended over universal strategies for enhancing wheat productivity while moderating environmental risk.
- Observation Year, biochar rate, fertilizer source and soil texture had significant main and interaction effects in the wheat trials.
