Improving soil organic matter is essential for healthy crop growth. To effectively increase the levels of organic matter in the soil, a balanced approach that combines both "opening up" and "controlling" is necessary. "Opening up" refers to increasing the amount of organic material added to the soil through sources like compost, green manure, and crop residues. "Controlling" involves minimizing the loss of existing organic matter by adopting sustainable farming practices such as crop rotation, reduced tillage, and proper nutrient management. In simple terms, the key methods are planting, returning, and practicing. Planting green manure crops, returning straw to the field, and applying organic fertilizers are all effective strategies. Planting green manure not only helps cover the soil but also significantly boosts its organic content. According to experimental data, adding 1 ton of green manure per year on any type of land can lead to an increase in soil organic matter by 0.1–0.2% after five years. It also raises total nitrogen by 0.011%, total humic acid by 6.1%, and active organic matter by 17.4%. These improvements help create a more fertile and resilient soil environment. Returning straw to the field is another effective way to enhance the return of biological production to the soil. Straw is rich in organic matter and essential minerals. If it's not returned to the field, these nutrients are lost, leading to long-term depletion of soil fertility. Using a microbial agent like goldfish fermentation can further enhance the decomposition and nutrient release of the straw, making it even more beneficial for the soil. Adding organic fertilizers such as gold treasure bacteria fertilizer improves soil structure, increases organic matter content, and supports a balanced soil ecosystem. Neglecting organic inputs while relying heavily on chemical fertilizers can disrupt this balance. For example, the famous black soil in Northeast China was once known for its high fertility. However, due to over-reliance on chemical fertilizers and underuse of organic materials, the soil has gradually lost its richness. The organic matter content has dropped from around 10% to just 1–5%, causing the once-black soil to turn yellow. This highlights the importance of maintaining a proper balance between organic and inorganic inputs for long-term soil health.
