Currently, agricultural production faces numerous challenges, such as unscientific fertilization practices, insufficient fertilizer input, imbalanced crop investment structures, and a one-sided focus on yield without considering the long-term effects on product quality. These issues have led to serious problems in crop growth, affecting both yield and quality. To address this, it is essential to promote new, scientific fertilization methods that can improve efficiency and sustainability.
One of the most important technologies to be widely adopted is the soil-balanced fertilization technique. This method begins by analyzing soil fertility levels and then combines this data with the specific nutrient needs of crops. Based on organic fertilizer inputs, appropriate amounts of nitrogen, phosphorus, potassium, and micronutrients are determined and applied directly to the fields. This approach represents a major shift in China’s fertilization practices, integrating modern agricultural science and technology for more efficient and sustainable farming.
Expanding the use of organic fertilizers is another critical step. Farmers should be encouraged to build and maintain “three facilities†— toilets, livestock areas, and compost pits — to collect and decompose organic materials. By maximizing the use of available organic resources, farmers can ensure sufficient organic matter is returned to the soil. It is recommended that at least 1,500 kg of organic fertilizer be applied per mu (approximately 667 square meters). This helps maintain soil health, improves land fertility, and supports long-term productivity.
The use of specialized compound fertilizers tailored for different crop types is also gaining importance. These fertilizers contain balanced proportions of nitrogen, phosphorus, potassium, and micronutrients, addressing the limitations of traditional fertilization methods. Compared to simple or conventional fertilizers, they offer better nutrient balance, longer-lasting effects, and higher efficiency. They reduce waste and increase nutrient absorption, with nitrogen utilization rising from 20% to 30%, and phosphorus and potassium increasing by 20% to 40%. Typically, 50–60 kg per mu is recommended for optimal results.
Another promising innovation is the application of highly efficient bio-organic compound fertilizers. Developed by national research institutions, this technology is considered one of the best in the world. It combines organic, inorganic, microbial, and synergistic components into a single product, offering rapid, steady, and effective nutrient supply. This blend increases nutrient uptake by 30% to 50%, boosts grain and cotton yields by 10% to 20%, and specialty crops by 20% to 30%. It also enhances soil quality, improves the environment, and supports green agriculture.
Finally, the application of potassium and trace elements plays a vital role in crop nutrition. In addition to using organic fertilizers and incorporating crop straw into the soil, applying chemical potash is an effective way to replenish soil potassium. Trace elements like boron, zinc, and molybdenum, though needed in small amounts, are crucial for certain crops. For example, fruit trees require boron to avoid issues like "flowers without fruits" or "buds without blooms." A typical application rate for boron is 0.5–1.0 kg per acre, or 100–200 g mixed with 40–50 kg of water for foliar spraying. Zinc is commonly used in rice, wheat, and corn at 1.0–1.5 kg per mu, while molybdenum is often applied to peanuts at 12 g per 100 kg of seeds. These practices help optimize crop performance and ensure long-term soil fertility.
