Bio-organic fertilizers have demonstrated significant potential in enhancing saline-alkali soil properties, boosting crop yield, and reducing chemical fertilizer dependency. However, the extent of improvement optimal application rates for varying conditions remain unclear. We conducted a 2-year field experiment (2022-2023) to evaluate effects different bio-organic on nutrient availability, cotton yield across three fields with salinity levels 4.58, 9.07, 12.76 g·kg⁻¹ (T1-T3). Four treatments were implemented, involving reductions 0% (CK), 20% (F1), 40% (F2), 60% (F3). Results indicated that, compared CK, reduced bulk density, salinity, pH by an average 15.84%, 53.86%, 7.5%, respectively. Concurrently, moisture content, organic matter, nitrogen, phosphorus, potassium, increased 36.72%, 58.4%, 59.4%, 77.9%, 88.7%, 50.32%, Notably, improvements properties more pronounced 2023 2022. Principal component analysis revealed that rate was mild, moderate, severely salinized fields. These findings provide scientific basis use while improving productivity sustainability soils.
