Maize is one of the world's most critical food crops, and its yield and quality directly impact global food security. In agricultural production, rational fertilization is a key measure to enhance maize productivity and quality. Foliar spraying of nitrogen fertilizer is a common practice that effectively replenishes soil nitrogen and promotes maize growth and development.

I. Effects of Foliar Nitrogen Fertilization

  1. Promotes Maize Growth Nitrogen is an essential nutrient for plant growth, playing a vital role in the development of maize stems, leaves, and flowers. Foliar nitrogen application provides sufficient nitrogen to meet the crop’s demands, thereby accelerating growth.

  2. Increases Yield Appropriate nitrogen levels enhance tillering, root development, and leaf quantity, boosting maize yields. Additionally, nitrogen improves photosynthetic efficiency, increasing the accumulation of photosynthates, which further stimulates growth and yield.

  3. Improves Quality Foliar nitrogen application raises protein content, enhancing taste and nutritional value. It also promotes starch accumulation, improving overall maize quality.

II. Methods for Applying Nitrogen Fertilizer

  1. Timing The optimal period for foliar nitrogen application is during the early growth stage of maize, when nitrogen demand is high. Spring (early growth) and summer/autumn are ideal times for application.

  2. Application Methods

    • Spraying: Dissolve nitrogen fertilizer in water and apply using a sprayer.
    • Drip Irrigation: Dissolve fertilizer in water and deliver it via pipelines near the roots. Choose methods based on specific conditions.
  3. Dosage Control Apply 5–10 kilograms of nitrogen fertilizer per mu (~0.067 hectares). Adjust dosage according to maize variety, soil fertility, and climate.

  4. Safety Precautions Avoid skin or eye contact with nitrogen solutions. Clean application equipment promptly to prevent environmental contamination.

III. Key Considerations for Nitrogen Application

  1. Avoid Overapplication Excessive nitrogen leads to excessive vegetative growth, reducing quality and yield. Use nitrogen judiciously.

  2. Prevent Mixing with Alkaline Substances Combining nitrogen fertilizers with alkaline materials reduces efficacy. Apply separately from other fertilizers.

  3. Coordinate with Other Fertilizers Combine nitrogen with phosphorus, potassium, and other nutrients to optimize fertilizer use and improve yield/quality.

  4. Soil Conditions Matter Factors like soil pH and organic matter influence nitrogen absorption. Tailor application plans to soil-specific needs.

Foliar nitrogen fertilization is an effective method to supplement soil nitrogen, enhance maize growth, and increase yields. To maximize benefits, control dosage, avoid overuse, pair with complementary fertilizers, and account for soil conditions. With scientific management, this practice can significantly improve maize productivity and quality, contributing to national food security.
