1、Foliar application of bioorganic fertilizer enhances plant nutrients

Foliar Bio-organic fertilizer (BIOF) enhanced soil properties including soil enzymes, except soil P and pH. The foliar application has mitigated the uptake of the cadmium and iron to the plants. Foliar organic fertilizer increased yield parameters, including fruit size and numbers.

2、我国微量元素肥料研究及应用的历程与展望

Applying micronutrient fertilizers is an effective measure to alleviate micronutrient deficiencies of crops. The large-scale and systematic research and application of micronutrient fertilizers in China began in the 1970s.

3、Effect of Nutrient Forms in Foliar Fertilizers on the Growth and

This research aimed to evaluate how different chemical forms of key nutrients, delivered through an advanced foliar product (PRO) and a standard formulation (TRA), influence maize performance when grown on contrasting soil types.

4、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.

5、A Case Study on the Effect of Foliar Nitrogen Fertilization on the

This study aims to show whether the use of foliar nitrogen fertilizers in combination with sulfur in a two-year field experiment with triticale stimulates the multiplication of selected groups of microorganisms and the level of soil enzymatic activity.

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

Chelated foliar fertilizers are effective for improving element utilization efficiency, crop yield, and quality. The physicochemical properties, molecular structure, chelating strength, and chelating rate of chelating agents modulate the effects of application of nutrients.

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 Fertilizer Overview and Analysis

Foliar fertilizer composition can vary with the type of product you opt for and its purpose — these products are often made for distinct families of plants to counter specific nutritional deficiencies.

Understanding Foliar Fertilizers: A Guide for Farmers

Micronutrient Foliar Fertilizers – These provide trace elements such as zinc (Zn), iron (Fe), boron (B), manganese (Mn), and copper (Cu), which are crucial for plant metabolism but needed in smaller quantities.

Foliar Feeding

Foliar feeding is defined as the application of liquid fertilizer directly to the leaves of plants, allowing for the absorption of essential nutrients like potassium, phosphorous, and nitrogen through the epidermis and stomata, thereby enhancing growth and increasing crop yield.

Foliar fertilizer, also known as foliar spray fertilizer, foliar nutrient supplement, etc., is a fertilizer directly applied to the surface of plant leaves. It is absorbed through the leaves, acts quickly, enhances stress resistance, promotes growth and development, and improves crop quality and yield. Foliar fertilizer is a type of microfertilizer, but not all microfertilizers are suitable for foliar application. Below are detailed explanations about foliar fertilizer:

1. Definition of Foliar Fertilizer Foliar fertilizer refers to fertilizers applied to plant leaves via spraying, including liquid, granular, and powdered formulations. They are directly absorbed by leaves, rapidly enhancing growth rates, disease resistance, stress tolerance, and fruit quality.

2. Characteristics of Foliar Fertilizer

• Rapid Absorption: Quickly absorbed by leaves, faster than soil fertilization.
• Resource Efficiency: Easy to use and reduces environmental pollution from soil application.
• Yield Increase: Promotes plant growth and boosts crop output.
• Quality Improvement: Enhances crop traits, such as sugar content and vitamin levels.
• Disease Reduction: Lowers the incidence of plant diseases and improves disease resistance.

3. Types of Foliar Fertilizer

• Water-Soluble Fertilizers: Dissolve in water for spraying (e.g., amino acid-based, algal extract-based).
• Oil-Based Fertilizers: Contain oils and require mixing with water (e.g., mineral oil-based).
• Emulsion Fertilizers: Milky formulations needing shaking before use (e.g., sodium alginate-based).
• Suspension Fertilizers: Suspended particles requiring shaking (e.g., polyethylene glycol-based).
• Solid Fertilizers: Granular forms dissolved in water (e.g., compound fertilizers).

4. Precautions for Use

• Select Appropriate Formulations: Choose based on plant type and growth stage.
• Dilute Properly: Follow product instructions to avoid overconcentration and damage.
• Uniform Application: Ensure even spraying to prevent localized overdose.
• Avoid Direct Sunlight: Apply in shade to maintain effectiveness.
• Follow with Watering: Irrigate after application to aid absorption.
• Safety First: Prevent ingestion or skin contact during use.

5. Practical Applications

• Fruit Trees: Example: Spraying microelement-rich foliar fertilizer on apple trees increases sugar content and taste.
• Vegetables: Example: Nitrogen-rich foliar fertilizer on cucumbers accelerates growth and yield.
• Flowers: Example: Potassium-rich foliar fertilizer enhances color and fragrance in roses.
• Grain Crops: Example: Phosphorus-containing foliar fertilizer boosts corn growth and productivity.

Foliar fertilizer, as a type of microfertilizer, offers advantages such as rapid absorption, resource efficiency, yield increase, quality improvement, and disease reduction. careful selection and proper usage are essential to maximize its benefits.
