Other claims from this paper (7)
- Association Higher nitrogen rates were associated with greater soil nitrate concentration in the 0–110 cm layer.
- Intervention effect Seventeen years of annual nitrogen application raised residual soil nitrate at 100–200 cm relative to the unfertilized control, with concentration increasing by rate.
- Association Soil nitrate at sowing was positively related to wheat grain nitrogen content.
- Association Soil nitrate at sowing was positively related to wheat grain yield.
- Intervention effect Nitrogen use efficiency declined with each increment of added nitrogen fertilizer.
- Association Nitrogen use efficiency was directly related to nitrogen harvest index and grain yield.
- Recommendation The authors recommend about 105 kg N ha−1 for spring wheat in the semiarid Loess Plateau.
