Simple answer: Rich organic matter, diverse nutrients, and living soil!

Longer answer:

1. Improve soil and fertilize soil. After organic fertilizers are applied to the soil, organic matter can effectively improve the physical and chemical conditions and biological properties of the soil, mature the soil, enhance the soil's fertilizer-retaining and fertilizer-supplying capabilities and buffering capabilities, and create good soil conditions for the growth of crops.

2. Increase output and improve quality. Organic fertilizers are rich in organic matter and various nutrients, providing nutrients for crops. After decomposition of organic fertilizers, it provides energy and nutrients for soil microbial activities, promotes microbial activities, accelerates the decomposition of organic matter, and produces active substances that can promote the growth of crops and improve the quality of agricultural products.

3. Improve fertilizer utilization. Organic fertilizers contain many nutrients but are relatively low in content and are released slowly, while chemical fertilizers have high nutrient content per unit, few ingredients and are released quickly. The two are used in reasonable combination and complement each other. The organic acids produced by the decomposition of organic matter can also promote the dissolution of mineral nutrients in soil and chemical fertilizers. Organic fertilizers and chemical fertilizers promote each other, which is beneficial to crop absorption and improves the utilization rate of fertilizers.

The above is a brief analysis of organic fertilizers, I hope it can help you choose organic fertilizers.
