Bio-Organic Fertilizer Combined with Different Amendments Improves Nutrient Enhancement and Salt Leaching in Saline Soil: A Soil Column Experiment

Salt-affected soils frequently experience leaching and desalination issues, which severely restrict plant growth water uptake. Hence, in this experiment, four treatments including CG (no amendments addition); OF (organic fertilizer OH Hekang amendment OB fulvic acid addition) were designed to examine the effect of organic on soil chemical properties, salt transport, laws coastal saline soil. The results showed that addition significantly reduced pH (8.47–8.52) content (2.06–2.34 g kg?1), while increasing matter content, available phosphorus, potassium. treatment has a higher phosphorus than other treatments. elevated ratio (32.95% 32.12%, respectively) by raising volume rate. Organic promoted Na+ (4.5–32%) SO42? (12–27%) compared CG. treatments, particularly treatment, not only increased nutrients but also ion leaching, improved permeability rates. Our may provide theoretical basis for revealing law
