Improving soil organic matter is essential for healthy crop growth and long-term soil fertility. To boost organic matter, it's important to take a balanced approach—both increasing the input of organic materials and minimizing their loss. This means focusing on two main strategies: "opening up" new sources of organic matter and "controlling" its depletion through smart farming practices. In simple terms, this involves three key actions: planting, returning, and practicing.
Planting green manure crops is one of the most effective ways to enhance soil health. These crops not only cover the soil and prevent erosion but also add valuable organic material when they decompose. According to field studies, adding just one ton of green manure per hectare annually over five years can increase soil organic matter by 0.1–0.2%, total nitrogen by 0.011%, humic acid by 6.1%, and active organic matter by 17.4%. It’s a natural and sustainable way to enrich the soil.
Returning crop residues like straw back to the field is another crucial practice. Straw is rich in carbon and minerals, and when left in the soil, it helps maintain nutrient levels and improve soil structure. If straw is removed or burned instead of being returned, it leads to a gradual loss of organic matter and nutrients, which can eventually harm soil fertility. Using a composting agent like golden fish bacteria can speed up the decomposition process and make the nutrients more available to plants.
In addition, applying organic fertilizers such as gold treasure bacteria fertilizer plays a vital role in maintaining soil balance. These fertilizers not only add organic matter but also promote beneficial microbial activity that enhances soil structure and water retention. Neglecting organic inputs in favor of chemical fertilizers can disrupt this balance. For example, China’s famous black soil in the northeast used to be extremely fertile, but due to over-reliance on chemical fertilizers and insufficient use of organic matter, its organic content has dropped from 10% to just 1–5% in some areas. As a result, once-black land is turning yellow, signaling a decline in fertility.
By combining these methods—planting green manure, returning straw, and using organic fertilizers—farmers can significantly improve soil quality and ensure long-term productivity.
