Other claims from this paper (8)
- Observation Safe nitrogen rates in the Non-Chernozem zone were 100-150 kg·ha-1 for mixed organic-mineral fertilization.
- Observation Safe nitrogen rates in the Non-Chernozem zone were 120-180 kg·ha-1 for mineral fertilization.
- Observation Nitrogen applied with organic fertilizers had lower availability and a smaller aftereffect.
- Association Wheat on chernozems had lower response to nitrogen fertilizer than on sod-podzolic soils.
- Method / resource The NUE indicator was applicable for connecting nitrogen efficiency with yield sustainability.
- Association Year-to-year variation in nitrogen output decreased when input exceeded 100 kg·ha-1.
- Association Rates over 250 kg·ha-1 showed nitrogen excess and higher environmental nitrogen losses.
- Recommendation The authors recommend increasing nitrogen fertilization to improve yield sustainability.
