- Intervention effect Layered nitrogen placement redistributed soil nitrate nitrogen, organic carbon, available phosphorus, and enzyme activities relative to shallow placement.
- Association Specific root length and area were greater in deeper soil under the changed soil conditions.
- Association Root nitrate reductase activity was higher under the changed soil conditions.
- Association Root nitrogen and phosphorus concentrations increased under the changed soil conditions.
- Observation Root functional strategies shifted toward greater acquisition.
- Observation Genes related to lateral root formation and root hair development were upregulated.
- Association The 8–16 cm soil layer explained 43.0% of yield variation and contributed most to yield formation.
- Intervention effect Layered nitrogen placement increased subsoil nutrient availability, root functional differentiation, and depth-specific transcriptional activation.
- Intervention effect Layered nitrogen placement promoted nutrient accumulation.
- Intervention effect Layered nitrogen placement increased grain yield.
