1、Foliar application of bioorganic fertilizer enhances plant nutrients

Results showed that fruit weight, fruit size and number of fruits per tree and total yield per tree were significantly increased in BIOF treatment by 10.2, 29.59, 13.56 and 31.9 percent respectively compared to CK.

2、Foliar Nutrition, Biostimulants and Prime

Particularly, Fe chlorosis is recognized as a suitable model to study foliar fertilization since it represents a common nutritional problem in several fruit crops, such as citrus, pear, and peach trees, grown on calcareous soils (Molassiotis et al., 2006).

3、Effects of Foliar Fertilization: a Review of Current Status and Future

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.

4、Foliar Nutrition in Vegetables

Foliar application is often timed to coincide with specific vegetative or fruiting stages of growth and the fertilizer formula is adjusted accordingly. In terms of nutrient absorption, foliar fertilization can be from 8 to 20 times as efficient as ground application.

5、Guide to Foliar Fertilization: Best Practices, Dosages, and Benefits

This guide provides a detailed overview of recommended application concentrations, key benefits, crop-specific usage, and technical considerations for successful foliar fertilization in agricultural practice.

Foliar Fertilization: Novel Approaches and Field Practices

In this Special Issue, special attention is paid to various aspects of foliar fertilization, especially with regard to plant growth and development, physiological traits, incidence of diseases and pest feeding, and quantity and quality of production.

Foliar fertilizers: Enhancing nutrient uptake for healthy plants

While foliar fertilization offers many benefits, proper application techniques are essential to maximize effectiveness and minimize potential risks. Factors such as spray volume, droplet size, adjuvant selection, and timing of application can all influence the efficiency of foliar nutrient uptake.

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.

Effects of Foliar Fertilization on Nutrient Uptake, Yield, and Fruit

The use of foliar fertilization enhanced the concentrations of P, K, and Mg in fruits, which have a strong correlation with fruit quality, leading to enhanced fruit quality.

Foliar Fertilization: Benefits, Uses & Importance for Crops

Foliar fertilization is an effective method of plant nutrition where nutrients are absorbed directly through the leaves instead of the roots. This method plays an increasingly important role in crop production, especially in cases where the soil is unable to provide plants with sufficient nutrients.

Foliar fertilizer is a commonly used nutrient source in modern agriculture. Applied by spraying directly onto plant leaves, it allows for rapid absorption and utilization. Foliar fertilization can effectively accelerate plant growth, enhance disease resistance, and improve fruit quality. The choice of fruit for foliar fertilization depends on the specific characteristics and nutritional needs of each crop. Below are detailed recommendations for several fruits well-suited for foliar fertilization:

1. Apple (Malus domestica)

Apple trees, widely cultivated globally, produce delicious and nutritious fruits. They thrive in fertile, well-drained soil. Foliar fertilization supplements nutrients, promotes growth, and enhances fruit quality.

• Timing: Apply before spring budding and after autumn defoliation, when leaves renew quickly and absorb nutrients efficiently.
• Dosage & Method: Dilute 200–300 ml of foliar fertilizer per mu (0.067 hectares) and spray evenly over leaves. Adjust based on specific conditions.
• Notes: Avoid applying during hot weather to prevent reduced absorption. Overuse may cause fertilizer damage.

2. Citrus (e.g., Oranges, Lemons, Grapefruits)

Citrus fruits are prized for their aroma and nutritional value. These trees require acidic soil (pH 5.5–6.5). Foliar fertilization replenishes essential nutrients, boosting growth and fruit quality.

• Timing: Apply before spring budding and after autumn defoliation, aligning with peak leaf renewal.
• Dosage & Method: Use 200–300 ml per mu, diluted and sprayed evenly. Adjust as needed.
• Notes: Avoid high temperatures and excessive application to prevent fertilizer burn.

3. Banana (Musa spp.)

Bananas, tropical favorites with unique flavor and nutrition, adapt to various soils but need abundant sunlight and water. Foliar fertilization optimizes nutrient uptake, growth, and fruit quality.

• Timing: Apply before spring budding and after autumn defoliation, when leaves absorb nutrients efficiently.
• Dosage & Method: Spray 200–300 ml per mu, adjusted based on conditions.
• Notes: Avoid heat and overapplication to prevent damage.

4. Strawberry (Fragaria × ananassa)

Strawberries, celebrated for their vibrant color, sweetness, and nutrition, require organic-rich soil. Foliar fertilization supplements nutrients, enhancing growth and fruit quality.

• Timing: Apply before spring budding and after autumn defoliation, matching leaf renewal periods.
• Dosage & Method: Use 200–300 ml per mu, diluted and sprayed evenly. Adjust as needed.
• Notes: Avoid high temperatures and excessive use to prevent harm.

5. Grape (Vitis vinifera)

Grapes, economically vital and nutritious, thrive in organic-rich soil. Foliar fertilization boosts nutrient intake, growth, and fruit quality.

• Timing: Apply before spring budding and after autumn defoliation, during peak leaf absorption.
• Dosage & Method: Spray 200–300 ml per mu, adjusted based on conditions.
• Notes: Avoid heat and overapplication to prevent fertilizer damage.

Selecting fruits for foliar fertilization requires consideration of growth traits, soil conditions, and climate. Scientific application methods and proper dosage control can improve fruit quality and yield while supporting sustainable agriculture.
