Why All Humic Acids Are Not Created Equal

What Is the Difference Between Humic Acid Products?

As the use of humic acid products continues to grow in agriculture, turf management, environmental applications, and home and garden markets, customers often ask an important question:

What is the difference between one humic acid product and another?

Humic products can vary considerably depending on their source material, processing method, humic acid concentration, and the other organic compounds present in the finished product.

Global Organics produces humic-based products designed to support soil health, nutrient availability, microbial activity, and plant development.

What Are Humic Substances?

Humic substances occur naturally in soils, sediments, and aquatic environments.

They are formed through the long-term decomposition and transformation of plant, animal, and microbial organic matter.

Unlike simpler organic compounds such as proteins, carbohydrates, and amino acids, humic substances consist of highly complex mixtures of naturally occurring organic molecules.

These materials play an important role in:

  • Soil organic matter

  • Nutrient cycling

  • Cation exchange capacity

  • Soil aggregation

  • Water retention

  • Microbial activity

  • Plant nutrient availability

Humic Acid vs. Fulvic Acid

Humic substances are traditionally classified according to their solubility under different pH conditions.

Humic Acids

Humic acids are generally insoluble under strongly acidic conditions but become soluble as pH increases.

Because of their relatively large and complex molecular structures, humic acids can contribute to soil structure, nutrient retention, and biological activity.

Fulvic Acids

Fulvic acids remain soluble across a much wider range of pH conditions.

Their smaller molecular size and greater solubility allow them to move more readily through soil and water.

Both humic and fulvic fractions can contribute to the overall performance of a humic-based soil amendment.

Why Humic Substances Are So Complex

Humic substances are not single, purified chemical compounds.

Instead, they are highly diverse mixtures of organic molecules created through natural decomposition processes.

Their composition can vary depending on:

  • Original plant and biological material

  • Geological conditions

  • Age of the deposit

  • Mineral composition

  • Environmental conditions

  • Extraction and processing methods

Because of this natural variability, two products labeled as humic acid may differ substantially in composition and performance.

How Humega® Is Produced

Global Organics uses a proprietary processing method to produce Humega®, a liquid humic product designed to retain a broad range of naturally occurring organic compounds.

The objective of this process is to provide humic substances while preserving additional organic components that may support soil biological activity and plant growth.

Laboratory analysis has measured Humega® at up to 8% humic acid using colorimetric analysis, while Global Organics guarantees a minimum 6% humic acid content using this analytical method.

Source Material Matters

The source of a humic product can influence its final chemical and mineral composition.

Global Organics selects source deposits intended to provide desirable humic characteristics while limiting excessive salts and other unwanted mineral constituents.

Careful source selection helps maintain the quality and consistency of the finished humic product.

Processing Methods Can Affect Humic Products

Humic materials may be extracted and processed using several different methods.

Some commercial products use strong alkaline extraction agents, including sodium hydroxide or potassium hydroxide, to separate humic substances from their source material.

Processing conditions can influence the chemical characteristics of the finished product and may affect which naturally occurring organic compounds remain after extraction.

For this reason, customers comparing humic products should consider more than the percentage of humic acid listed on the label.

Important factors may include:

  • Source material

  • Extraction method

  • Humic acid concentration

  • Fulvic acid content

  • Salt content

  • Mineral composition

  • Additional organic compounds

  • Product consistency

More Than Humic Acid Percentage

A higher humic acid percentage does not automatically mean that one product will perform better than another.

The overall effectiveness of a humic amendment depends on its composition, application rate, soil conditions, crop requirements, and management program.

Humega® is formulated to provide humic substances along with naturally derived organic components intended to support the biological and chemical functions of healthy soil.

Supporting Soil and Plant Health with Humega®

Humic-based products may help support:

  • Soil structure

  • Nutrient retention

  • Nutrient availability

  • Soil microbial activity

  • Root-zone development

  • Water-holding capacity

  • Fertilizer efficiency

Global Organics developed Humega® as a comprehensive humic product for use in agriculture, turf, environmental management, and home and garden applications.
