Soil aeration improves tomato fruit yield by regulating root characteristics and soil nitrogen cycle.

ABSTRACT: Soil aeration plays a critical role in regulating root development and soil nutrient dynamics, which are essential for optimizing tomato fruit yield. However, the mechanisms underpinning how different soil aeration techniques influence root characteristics and soil nitrogen cycling remain underexplored. This study aims to evaluate the effects of micro-nano bubble aeration and underground air layer treatments on soil oxygen concentration, root morphology, nitrogen cycling, and ultimately tomato fruit yield. A two-season field experiment was conducted in Xi'an, China. Micro-nano bubble aeration treatments were applied before irrigation with dissolved oxygen levels set at 6.5 mg/L (N1) and 8.0 mg/L (N2). Additionally, underground air layer treatments were implemented without vertical pipes (L
