Straw return enhances soil biological properties by increasing carbon and energy availability, thereby improving conditions for microbial communities. However, the introduction of beneficial bacteria, such as Bacillus subtilis, can further shape rhizosphere bacterial composition. In this study, we combined sugarcane straw with B. subtilis inoculation to test whether synergy reduces specialization in rhizosphere.

Saline-alkali land represents a crucial reserve of arable essential for ensuring food security. However, there remains significant deficiency in converting saline-alkali into productive cultivated or grazing areas. Microbial agents hold substantial potential the reclamation soils. In this study, moderately halophilic bacterium, Bacillus halophilus BH-8, was screened from coastal saline soil. We combined strain BH-8 with coal gangue to create composite microbial agent, which shown effectively increase levels available nitrogen, phosphorus, potassium, and organic matter, while reducing pH value Moreover, it significantly enhanced activity various enzymes altered community composition soil, notably increasing abundance Pseudomonas Bacteroidota. These results demonstrate application agent rehabilitating highlight as promising candidate research.

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.
