Corn fertilization method

As temperatures continue to rise, farmers are entering the busy season of spring plowing and corn fertilization. The process of applying fertilizer to corn has become a major concern for many agricultural workers. To ensure effective and safe fertilization, it is essential to follow these key technical guidelines: 1. **Deep Fertilization**: Apply fertilizer at a depth of 10–15 cm, ensuring that it is separated from the seeds by 8–10 cm. This helps prevent seed burn and ensures better nutrient absorption. 2. **Balanced Nutrient Proportion**: A proper balance of nitrogen (N), phosphorus (P), and potassium (K) is crucial for healthy corn growth. During the growing season, corn requires more nitrogen and potassium while needing less phosphorus. Nitrogen and potassium are more efficiently absorbed by plants, whereas phosphorus has a lower utilization rate. Therefore, it's recommended to focus on nitrogen application, with an appropriate amount of phosphorus and potassium. Additionally, soil testing should be used to determine the right ratio based on soil fertility and crop needs. 3. **Appropriate Fertilizer Quantity**: The amount of fertilizer applied should be determined based on soil fertility levels and expected yield. Soil test results serve as the foundation for deciding the correct dosage, helping to avoid over-fertilization or under-fertilization. 4. **Fertilization Techniques**: Combine base fertilizer with top-dressing to ensure a steady supply of nutrients throughout the growth stages. This approach not only supports plant development but also improves the efficiency of fertilizer use. 5. **Proper Application Method**: When using ridge cultivation, first plow the field and apply fertilizer in the furrow before forming the ridge. For fields with uneven terrain, ridging should be done before planting, or it can be combined with machinery to keep the seed and fertilizer separated by 8–10 cm, preventing damage to young plants. By following these practices, farmers can optimize their fertilization strategies, reduce waste, and enhance both crop quality and yield. It’s important to stay informed about the latest agricultural techniques and adapt them to local conditions for the best results.
