1、Humic Acid Fertilizer Improved Soil Properties and Soil Microbial

Humic acid is a kind of organic matter produced and accumulated by animal and plant remains through the decomposition and transformation of microorganisms with a series of geochemistry...

2、Studies on the humic acid structure and microbial nutrient restriction

There were few studies on humic acid structure during organic-inorganic co-composting, and studying this was conductive to elucidate the action mechanism of humic acid on inorganic nutrients.

3、Does humic acid fertilizer belong to organic fertilizer? How do I use

Humic acid organic fertilizer is a kind of organic fertilizer mainly containing humic acid, which is formed by the decomposition of plant residues. It widely exists in soil, river mud and shallowly buried weathered coal, peat and lignite.

4、Humic and fulvic acids: nutrients in organic fertilizers

To start with humic acids, which is a collection of organic compounds that are formed during the digestion of raw organic matter. Then fulvic acids, who are also a collection of organic compounds, but it are smaller molecules than humic acids.

5、Humic Acid Fertilizer Uses: Role, Application Methods, Dosage, and

Humic Acid is an organic compound in mature organic matter and prehistoric deposits. It’s made up mostly of carbon, hydrogen, oxygen, and about 4% nitrogen. It can be found naturally in leonardite and humalite deposits and artificially made by oxidizing coal deposits.

What are Humic Fertilizers

Humic fertilizers are a type of organic soil amendment that can help improve soil health and plant growth. These fertilizers are derived from humic substances, which are naturally-occurring organic compounds found in soil, peat, coal, and other geological deposits.

What Is Humic Acid Fertilizer? Unlocking Soil Potential

A: Humic acid fertilizer is a type of fertilizer made from humic acid, a complex organic compound composed of carbon, hydrogen, oxygen, and nitrogen. It’s a byproduct of the decomposition of plant and animal matter and is rich in nutrients and beneficial microorganisms.

HUMIC ACID

(HA) is a principal component of humic substances which is the major organic constituents of soil, peat, coal, dystrophic lakes and ocean water. It is produced.

Humic Acid Fertilizer: What It Is and Its Key Benefits

Humic and fulvic acids are components of humic substances, organic compounds found in soil. While both originate from decomposed organic matter, they differ in molecular size, solubility, and primary functions in soil and plants.

Humic acid fertilizers are organic fertilizers derived from the decomposition of animal and plant residues under microbial action. They are complex fertilizers containing multiple nutrients. Characterized by unique biological activity and multifunctionality, humic acid fertilizers hold broad application prospects in agricultural production. Below is a detailed analysis of their classification, properties, applications, and market dynamics.

I. Classification of Humic Acid Fertilizers

1. By Source:

   • Animal-based humic acid: Derived from animal manure (e.g., cow dung, chicken manure).
   • Plant-based humic acid: Derived from plant residues (e.g., straw, fallen leaves).

2. By Components:

   • Fulvic acid: Known for its water solubility and rapid absorption.
   • Humic acid: Main component with strong soil-binding capacity.
   • Hymatomelanic acid: Intermediate properties between fulvic and humic acids.

3. By Form:

   • Liquid humic acid: Suitable for foliar spraying or irrigation.
   • Solid humic acid: Used as soil amendments or granular fertilizers.
   • Gaseous humic acid: Rarely used; primarily in specialized applications.

II. Properties of Humic Acid Fertilizers

1. High Organic Matter Content:

   • Rich in nutrients that promote crop growth.
   • Improves soil structure, enhancing water and nutrient retention.

2. Biological Activity:

   • Stimulates root development and enzyme activity.
   • Enhances crop resistance to diseases, pests, and environmental stress.

3. Multifunctionality:

   • Balances soil pH and buffers salinity.
   • Chelates essential micronutrients (e.g., Fe, Zn) for better uptake.

III. Applications of Humic Acid Fertilizers

1. Soil Amendment:

   • Rejuvenates degraded soils by increasing porosity and microbial activity.
   • Reduces reliance on chemical fertilizers.

2. Crop Growth Promotion:

   • Particularly beneficial for acid-loving crops (e.g., tea, potatoes).
   • Improves yield and nutritional quality of fruits, vegetables, and grains.

3. Stress Resistance:

   • Mitigates damage from drought, salinity, and heavy metals.
   • Strengthens cell membranes and antioxidant systems in plants.

4. Sustainable Agriculture:

   • Biodegradable and eco-friendly, reducing environmental pollution.
   • Promotes circular agriculture by utilizing organic waste.

IV. Market Dynamics

1. Growing Demand:

   • Rising awareness of sustainable farming drives global market growth.
   • High demand in developing regions facing soil degradation (e.g., Africa, Southeast Asia).

2. Technological Innovations:

   • Nano-coated humic acids and slow-release formulations improve efficiency.
   • Bioengineered strains enhance humic acid extraction from low-cost sources.

3. Policy Support:

   • Subsidies and incentives for organic farming in countries like China, India, and Brazil.
   • Inclusion of humic acid products in green certification programs (e.g., EU Ecolabel).

Humic acid fertilizers, as organic inputs, offer significant advantages in nutrient supply, soil health, and crop resilience. Despite higher costs compared to synthetic fertilizers, their eco-friendly nature and long-term benefits position them as a key tool for sustainable agriculture. Future advancements in production and formulation will likely expand their adoption globally.
