Other claims from this paper (15)
- Observation Soil alkali-hydrolyzable nitrogen under N0 decreased then increased during growth.
- Observation In other nitrogen treatments, soil alkali-hydrolyzable nitrogen fell, rose after topdressing, fell again, then rose after boll opening.
- Observation Soil available potassium fell and then rose at both locations.
- Observation Available soil nutrients decreased with soil depth.
- Observation In Nanjing fertilized plots, soil alkali-hydrolyzable nitrogen decreased farther from cotton plants.
- Observation In Nanjing fertilized plots, soil available phosphorus decreased farther from cotton plants.
- Observation Under N0, soil alkali-hydrolyzable nitrogen and phosphorus had no significant horizontal variation.
- Observation Soil alkali-hydrolyzable nitrogen varied more across space and time in Nanjing than Anyang.
- Observation Soil available phosphorus varied more across space and time in Anyang than Nanjing.
- Observation Soil available potassium decreased farther from cotton plants in Nanjing 0–60 cm layers and Anyang 20–60 cm layers.
- Observation Soil available potassium increased farther from cotton plants in Anyang 0–20 cm layers.
- Intervention effect At 360 kg ha-1 in Anyang, cotton yield components were relatively optimal and yield maximal.
- Intervention effect At 240 kg ha-1 in Nanjing, cotton yield was maximal.
- Intervention effect At the stated regional nitrogen levels, cotton fiber length and strength were better.
- Recommendation The authors recommend region-specific fertilizer rates based on spatial and temporal soil nutrient variation.
