Amino acids, humic acid, and fulvic acid are all valuable organic substances used in agriculture to enhance plant growth and soil health. However, they differ in composition, function, and application.

1. Amino Acids
Source: Derived from plant or animal proteins through hydrolysis.
Function:
Directly absorbed by plants to boost metabolism and stress resistance.
Enhance nutrient uptake and photosynthesis.
Application: Foliar sprays, seed treatments, and hydroponic solutions.
2. Humic Acid
Source: Extracted from decomposed organic matter (peat, leonardite).
Function:
Improves soil structure and water retention.
Binds nutrients, reducing leaching.
Application: Soil conditioner, granular fertilizers.
3. Fulvic Acid
Source: A smaller, more soluble fraction of humic substances.
Function:
Increases nutrient solubility for better absorption.
Stimulates root growth and microbial activity.
Application: Liquid fertilizers, foliar sprays.
Conclusion
Amino acids feed plants directly, humic acid improves soil, and fulvic acid enhances nutrient mobility. Combining them can maximize crop performance sustainably.
