Foliar feeding of tomatoes in open ground: an effective scheme for 2025

Foliar feeding of tomatoes in open ground: an effective scheme for 2025. During the phase of formation of the first tassel and until the beginning of ripening, tomatoes actively form a crop.

Foliar fertilization is a critical measure for improving yield and quality in open-field tomato cultivation. Selecting the appropriate foliar fertilizer is essential to ensure healthy growth. Below, I will detail suitable foliar fertilizers and their application methods to help you better understand and choose the optimal options for your crops.

1. Criteria for Selecting Foliar Fertilizers

(1) Comprehensive Nutrient Content

• Nitrogen (N), Phosphorus (P), Potassium (K): These are foundational elements for plant growth. Nitrogen promotes leaf development, phosphorus supports root growth, and potassium enhances disease resistance.
• Micronutrients: Such as iron, zinc, and copper, which are vital for plant health. While less prominent than macronutrients, deficiencies can lead to physiological disorders.
• Organic Matter: Provides essential nutrients, improves soil water retention, and enhances aeration.

(2) High Safety

• Harmless Treatment: Choose fertilizers treated to minimize residual chemicals, reducing environmental and human health risks.
• Hormone-Free: Avoid products containing plant hormones to prevent abnormal growth or toxicity.

2. Types of Foliar Fertilizers and Their Applications

(1) Water-Soluble Fertilizers

• Characteristics: Easy to apply, high absorption efficiency.
• Advantages: Rapid effects, ideal for urgent nutrient needs.
• Disadvantages: Higher cost.

(2) Oil-Based Fertilizers

• Characteristics: Stable, low volatility, easy storage and transport.
• Advantages: Convenient for targeted spraying.
• Disadvantages: Slower absorption.

(3) Suspension-Type Fertilizers

• Characteristics: Uniform composition, good suspension to prevent sedimentation.
• Advantages: Ensures even distribution during spraying, aiding nutrient uptake.
• Disadvantages: Avoid contact with strongly alkaline substances.

(4) Solid Powder Fertilizers

• Characteristics: Stable, long shelf life.
• Advantages: Suitable for long-term storage and use.
• Disadvantages: Requires dissolution before application, adding operational steps.

3. Timing and Methods of Application

(1) Optimal Timing

• Before Flowering: High nutrient demand during this period supports flower bud differentiation and fruit development.
• Fruiting Stage: Crucial for improving fruit quality and yield.

(2) Application Methods

• Spot Spraying: Target specific areas like leaf undersides or stem bases.
• Strip Spraying: Apply vertically along the main stem for broad coverage.
• Surround Spraying: Spray around plants, suitable for large-scale fields.

4. Key Considerations

(1) Adjust Based on Soil Conditions

Nutrient needs vary with soil fertility. Tailor applications flexibly to crop requirements.

(2) Avoid Overapplication

Excessive use wastes resources and risks soil salinization. Apply judiciously.

(3) Consider Weather

Avoid application during rainy or cold weather to prevent nutrient loss or growth disruptions.

By following these guidelines, you can select the most suitable foliar fertilizer for open-field tomatoes, optimize application timing and methods, and achieve superior yields and quality. Proper foliar fertilization not only boosts productivity but also provides essential nutrients for robust plant health.
