e0“The soil organic carbon content in N2 was significantly higher; the soil C/N ratio was highest in N2, and T3 resulted in a significantly higher C/N ratio than T1 under the same N level; total soil respiration in N0 was significant lower, and T4 had higher respiration than T2 under the same N level.”

- Intervention effect Wheat yield increased with nitrogen.
- Observation Wheat yield peaked at 8949.81 kg·hm−2 under N2T3.
- Intervention effect Irrigation alone had no significant effect on wheat yield.
- Intervention effect At equal nitrogen rates T1 and T2 yielded less than T3 and T4.
- Intervention effect Soil organic carbon was higher under N2.
- Intervention effect T3 increased soil C/N over T1 at equal nitrogen.
- Intervention effect Soil respiration was lower under N0.
- Intervention effect T4 raised soil respiration over T2 at equal nitrogen.
- Intervention effect Nitrogen addition increased four soil microbial groups.
- Intervention effect Nitrogen addition decreased Proteobacteria and Acidobacteriota.
- Intervention effect Nitrogen addition did not reduce fungal phyla.
- Intervention effect Nitrogen upregulated pentose phosphate pathway enzymes.
- Intervention effect Irrigation increased phosphoserine aminotransferase abundance.
- Intervention effect Irrigation decreased methylmalonyl-CoA mutase abundance.
- Observation N2T3 maintained high soil carbon while attaining maximum wheat yield.
- Intervention effect N2T3 improved water use efficiency relative to T4.
- Recommendation The authors identify N2T3 as the best balance of yield and soil carbon sequestration.
