Effects of Foliar Fertilization: a Review of Current Status

Foliar fertilizer application after soil fertilization is an effective method to increase the contents of trace elements in crops and crop yield, and to improve the soil environment. However, the application of inorganic foliar fertilizer results in difficulties in nutrient absorption and migration in plants.

Foliar nutrition: Potential and challenges under multifaceted

The potential of foliar fertilization in improving crop yield and quality under environmental stresses has been evaluated based on a meta-analysis. Foliar-applied fertilizers showed higher crop plants yield and quality traits by 15–19% and 9–29%, respectively, under different environmental stresses.

Corn is one of the world's most important food crops, and its yield and quality are influenced by various factors. The grain-filling stage is a critical period in corn's growth cycle, determining final yields. During this phase, corn plants require sufficient nutrients to support ear formation, kernel development, and maturation. Selecting the appropriate foliar fertilizers is crucial for improving corn productivity. Below is a detailed guide on effective foliar fertilizers for corn during the grain-filling stage.

I. Characteristics and Nutrient Requirements During the Grain-Filling Stage

1. Key Characteristics: The grain-filling stage spans from flowering to kernel maturity. During this period, corn plants have heightened nutrient demands to promote ear development, kernel充实 (filling), and stress resistance. Growth accelerates, and nutrient uptake increases significantly.

2. Nutrient Needs:

   • Macronutrients: Nitrogen (N), phosphorus (P), and potassium (K) are critical.
     • Nitrogen supports stem and leaf growth.
     • Phosphorus aids root development and reproductive structures.
     • Potassium enhances disease resistance and kernel quality.
   • Micronutrients: Zinc (Zn), iron (Fe), and others are essential for metabolic processes. Deficiencies can stunt growth or cause physiological disorders.

II. Selection of Foliar Fertilizers

1. Nitrogen-Based Fertilizers:

   • Role: Promotes vegetative growth and photosynthesis, providing energy for ear and kernel development.
   • Caution: Excessive nitrogen causes excessive stalk elongation, reducing kernel quality. Use balanced doses.

2. Phosphorus-Based Fertilizers:

   • Role: Enhances root systems and reproductive structures, improving yield and kernel plumpness.
   • Caution: Overapplication leads to yellowing leaves and abnormal ears. Stick to recommended rates.

3. Potassium-Based Fertilizers:

   • Role: Strengthens disease resistance, improves kernel density, and boosts marketability.
   • Caution: High concentrations may burn leaves. Apply in moderation.

4. Micronutrient Fertilizers:

   • Key Nutrients: Zinc, iron, manganese (Mn), etc.
   • Role: Prevents deficiencies (e.g., stunted growth, poor pollination) and ensures healthy development.

5. Compound Fertilizers:

   • Advantage: Combines multiple nutrients (N-P-K + microelements) for comprehensive nutrition. Adjust formulations based on soil tests and crop needs.
   • Note: Follow usage guidelines to avoid over-fertilization.

III. Application Methods

1. Timing:

   • Apply in early morning or late afternoon to reduce evaporation and enhance absorption. Avoid midday heat.

2. Concentration:

   • Follow product instructions or expert recommendations. Overly diluted solutions reduce effectiveness, while overly concentrated ones risk damage.

3. Target Areas:

   • Spray on stems, leaves, and ear silks. Focus on upper canopy for optimal absorption.

4. Frequency:

   • Typically, 1-2 applications during the grain-filling stage. Adjust based on weather, soil conditions, and plant health.

IV. Key Considerations

1. Monitor Plant Response:

   • Observe for signs of over-fertilization (e.g., leaf scorch, yellowing) or deficiency. Adjust strategies promptly.

2. Scientific Fertilization:

   • Combine foliar feeding with base fertilizers (pre-plant) and side-dressing (soil application). Avoid relying solely on foliar sprays.

3. Environmental Factors:

   • Heat: Avoid spraying during droughts; increase frequency if soil moisture is low.
   • Rainfall: Reapply if heavy rain washes off fertilizer.

4. Integrated Nutrient Management:

   • Supplement with organic fertilizers (e.g., compost) to improve soil health and provide sustained nutrients.

The grain-filling stage is critical for corn yield potential. Optimal foliar fertilization requires balancing macro- and micronutrients, adhering to application guidelines, and monitoring environmental conditions. By tailoring fertilizer types, concentrations, and timing, farmers can maximize kernel development, enhance stress resilience, and achieve higher-quality yields.
