With the deepening of the concept of sustainable agricultural development, the reduction of chemical fertilizers and organic substitution have become important ways to improve crop yield and quality and protect the soil ecological environment. This study focuses on the fertilization mode of replacing part of the chemical fertilizer with organic fertilizer, systematically explores its effects on soybean yield, growth indicators and quality factors, and evaluates its feasibility and advantages. The results show that a moderate proportion of organic fertilizer substitution not only helps to improve the root vitality and biological yield of soybeans, but also improves the physical and chemical properties of the soil to a certain extent, and promotes nutrient absorption and utilization efficiency. Compared with the full chemical fertilizer treatment, the 50% substitution ratio performs better in multiple indicators, reflecting good yield stability and ecological benefits. This study systematically analyzes the yield performance and soil improvement effects under different substitution ratios, providing a theoretical basis and practical path for green and efficient planting models, so as to promote the ecological and sustainable development of soybean production.
