1、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.

2、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.

Foliar Nutrition in Vegetables

Observed effects of foliar fertilization have included in yield increase, resistance to diseases and insect pests, improved drought tolerance and enhanced crop 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.

Research Progress on Role and Mechanisms of Foliar Fertilizer in

Foliar fertilization can enhance the antioxidant activity of crops, regulate photosynthetic activity, energy metabolism and nutrient assimilation and other physiological processes to promote crop growth.

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.

Effects of Organic Foliar Fertilizers on Vegetable Crop Productivity

Traditionally, foliar fertilization has been used as an additional measure to eliminate nutrient deficiencies, but there is currently a trend towards the widespread use of foliar treatments with various fertilizer types (Carr et al., 2015).

Foliar Fertilization and its Role in Vegetable Production

From a practical standpoint, most fertilizers have the potential to injure plants when applied as foliar fertilizers unless they are sufficiently diluted. If a grower does not mix and apply foliar fertilizers correctly, significant plant injury (burning) may be observed.

Foliar Feeding of Vegetable Crops: An Overview of Why, Why Not, and

Proponents of foliar feeding mention that it can: a) be highly tailored, b) bypass soil-based issues, c) lessen the potential for leaching or other losses, and d) create quick responses that may boost crop quality and/or reduce or help plants recover from stress.

Foliar spraying of fertilizers on vegetables is a modern agricultural technique that involves applying nutrients directly onto the leaves of plants, allowing for rapid absorption by the植株. This method offers the following benefits:

1. Enhanced Nutrient Utilization: By delivering nutrients directly to the plant's roots and stems via foliar application, nutrient uptake efficiency is significantly improved. This is particularly crucial for vegetable varieties with weaker root systems.

2. Reduced Environmental Pollution: Unlike soil-based fertilization, foliar spraying prevents nutrient accumulation in the soil, thereby minimizing environmental contamination. It also mitigates issues like soil salinization caused by excessive fertilization.

3. Promotes Crop Growth: Foliar-applied nutrients quickly replenish essential elements, stimulating crop growth. For instance, spraying potassium dihydrogen phosphate can lead to plumper fruits in tomatoes and peppers, enhancing yield.

4. Increased Stress Resistance: The application strengthens plants' disease resistance and resilience against pests and diseases. Micronutrient foliar sprays, for example, effectively prevent yellow leaf disease and powdery mildew in tomatoes and peppers.

5. Resource Efficiency: Foliar fertilization reduces soil fertilization costs. A case in point: using potassium dihydrogen phosphate on tomatoes and peppers can boost yields by over 10%, while soil fertilization costs are only a third of those for foliar application.

6. Ease of Operation: Directly targeting the leaves simplifies the process. nutrient concentrations can be adjusted according to crop needs, ensuring flexibility.

7. Improved Quality: Foliar feeding enhances crop quality. Micronutrient sprays, for example, elevate the taste and nutritional value of tomatoes and peppers.

8. Space Optimization: Since it doesn't require soil space, this method is ideal for densely planted or limited land areas.

9. Crop-Specific Adaptability: Tailored to diverse crops, such as using potassium dihydrogen phosphate for tomato and pepper fruit development, or micronutrients to combat specific diseases.

10. Eco-Friendly: Foliar applications leave no residuals, preserving environmental integrity. They also contribute to biodiversity, fostering ecological balance.

foliar fertilization for vegetables boasts numerous advantages, including heightened nutrient efficiency, reduced environmental impact, accelerated growth, enhanced resilience, cost-effectiveness, operational simplicity, quality improvement, space optimization, crop versatility, and environmental sustainability. Consequently, it stands as a highly recommended and applicable modern agricultural practice.
