Other claims from this paper (12)
- Intervention effect Excess irrigation and fertilizer did not significantly enhance nitrogen accumulation in cotton bolls.
- Observation Nitrogen transport efficiency decreased by 25.1% and 26.1%.
- Observation Nitrogen reproductive efficiency contributions to seeds decreased by 25.2% and 17.8%.
- Intervention effect Higher nitrogen application reduced nitrogen allocation to cotton bolls.
- Intervention effect Higher fertilizer and irrigation levels spread soil nitrate deeper and wider.
- Observation Ammonia was the primary reactive nitrogen loss from cotton fields, at 7.8–24.8 kg N ha−1.
- Intervention effect More intensive irrigation decreased nitrogen surplus.
- Observation Nitrogen deficiency occurred below 250 kg N ha−1.
- Observation Excess nitrogen occurred above 350 kg N ha−1.
- Intervention effect An irrigation lower limit of −20 kPa increased nitrogen accumulation in cotton bolls.
- Recommendation The authors recommend 275–307 kg N ha−1 to avoid nitrogen deficiency or excess.
- Observation The recommended system achieved a nitrogen footprint of 7.7–8.4 kg N t−1.
