Review of Fertilizer Types, Benefits, and Sustainable Use in Modern

It discusses the major categories of fertilizers—namely inorganic, organic, biofertilizers, and controlled-release types—highlighting their advantages, limitations, and specific functions in different cropping systems.

Foliar fertilizers in the modern fruit industry come in a wide variety, which are extensively used in the nutritional management of fruit trees based on their composition, mechanisms of action, and application methods. Below are some common types of foliar fertilizers along with their characteristics:

1. Seaweed Fertilizers:

   • Main Components: Rich in minerals and vitamins essential for plant growth, derived from seaweed.
   • Mechanism of Action: Provides trace elements such as iron, zinc, manganese, copper, and boron, enhancing fruit quality and yield.
   • Application Method: Typically applied via foliar spraying, or mixed with water for direct application to the trunk or roots.

2. Amino Acid Fertilizers:

   • Main Components: Contain various amino acids like aspartic acid and glutamic acid that promote plant growth.
   • Mechanism of Action: Stimulates enzyme activity within plants, facilitating nutrient absorption and conversion, thereby improving fruit quality.
   • Application Method: Can be sprayed or soaked onto leaves, or mixed with water for application to the trunk or roots.

3. Humic Acid-Based Fertilizers:

   • Main Components: High in organic matter and trace elements, improving soil structure and water/nutrient retention.
   • Mechanism of Action: Promotes root development, enhances nutrient uptake, and improves fruit taste and quality.
   • Application Method: Used as a base fertilizer or mixed with water for root/leaf application.

4. Trace Element Fertilizers:

   • Main Components: Include essential micronutrients like iron, zinc, manganese, copper, and boron.
   • Mechanism of Action: Supplements deficient elements, supporting normal growth and boosting fruit quality and output.
   • Application Method: Usually sprayed onto leaves or applied to the trunk/roots after mixing with water.

5. Compound Foliar Fertilizers:

   • Main Components: A combination of single-component fertilizers tailored to different growth stages of fruit trees.
   • Mechanism of Action: Offers comprehensive nutrition, promoting tree growth and enhancing fruit quality and yield.
   • Application Method: Primarily through foliar spraying, but can also be applied to the trunk/roots when mixed with water.

6. Microbial Inoculants:

   • Main Components: Beneficial microorganisms like nitrogen-fixers, phosphate-solubilizers, and potassium-releasers, along with plant growth regulators.
   • Mechanism of Action: Improves soil health, strengthens disease resistance, and fosters plant growth.
   • Application Method: Used as base/topdressing fertilizers or applied to roots/leaves after dilution.

7. Bio-Organic Fertilizers:

   • Main Components: Made from fermented animal/plant residues, rich in organic matter and microbes.
   • Mechanism of Action: Enhances soil fertility and supports healthy plant development.
   • Application Method: Suitable as base/topdressing fertilizers or for root/leaf application when mixed with water.

8. Hormone-Based Foliar Fertilizers:

   • Main Components: Plant hormones such as auxins, gibberellins, and cytokinins that regulate growth processes.
   • Mechanism of Action: Stimulates growth and improves fruit quality and productivity.
   • Application Method: Sprayed onto leaves or applied to the trunk/roots post-dilution.

9. Photosynthetic Nutrient Solutions:

   • Main Components: Nutrients required for photosynthesis, including carbon dioxide, water, and inorganic salts.
   • Mechanism of Action: Provides ample raw materials for photosynthesis, driving plant growth.
   • Application Method: Used as base/topdressing fertilizers or applied to roots/leaves after mixing with water.

10. Chelated Trace Element Fertilizers:

    • Main Components: Micronutrients in chelated form (e.g., iron, zinc, copper) for enhanced plant uptake.
    • Mechanism of Action: Boosts the absorption efficiency of trace elements, supporting growth.
    • Application Method: Typically sprayed onto leaves or applied to the trunk/roots when diluted.

the modern fruit industry offers a diverse range of foliar fertilizers, each with unique compositions, functions, and application methods. When selecting foliar fertilizers, factors such as specific tree requirements, soil conditions, and climate should be considered to achieve optimal fertilization outcomes.
