Animal Feed
Sodium humate is a versatile feed and water additive used in livestock and aquaculture production. Its humic substances may help support a balanced intestinal environment, improve digestive function, and enhance nutrient utilization, contributing to healthier growth and better feed efficiency. Sodium humate can also bind certain undesirable compounds in the digestive tract
OUR STORY
From Lignite Seams to Living Soil
organiccarbon.net is Saint Humic Acid’s platform for soil organic carbon (SOC): the lignite- and leonardite-derived humic acid, fulvic acid, and humate inputs that rebuild the carbon fraction of cultivated soil. This chemistry underpins our Carbon Fertilizer line — Carbon Base Plus, Carbon Guard, and Carbon Rich Base Fertilizer — built to return stable organic carbon to depleted, high-intensity farmland.
- Agriculture: Rebuilding soil organic carbon to improve structure, water retention, and nutrient efficiency.
- Industry: Providing additives for drilling mud, battery expanders, and ceramic binders.
- Animal Feed: Developing natural additives to improve livestock digestion and immunity.
- Environmental Protection: Using humic substances for heavy metal removal and wastewater treatment.

Core Products
Saint Humic Acid’s product catalog is categorized by its chemical base and intended industry application. “Main Products” are generally grouped into the following four categories:
Humic Acids
Humic acids are macromolecules containing various functional groups (like carboxyl and phenolic groups) that give them a high “cation exchange capacity.” This is a fancy way of saying they are excellent at grabbing onto nutrients and holding them.
Sodium Humate
While regular humic acid is often slow-releasing and only partially soluble, sodium humate is the sodium salt of humic acid. It is created by reacting humic substances (like leonardite or peat) with sodium hydroxide (NaOH).
Potassium Humate
It is produced by extracting humic acid from leonardite using potassium hydroxide (KOH). The result is a highly soluble,”plant-ready” salt that provides two benefits in one: the soil-conditioning power of humic acid and a boost of essential potassium (K).
Fulvic Acid
Fulvic acid is the smallest, lightest, and most biologically active fraction of humic substances. While humic acid is a large molecule that mostly stays in the soil to improve its structure, fulvic acid is small enough to pass directly through plant cell membranes—taking nutrients with it.
Amino Acid
In nature and in premium fertilizers, amino acids rarely exist in isolation. They are often bonded together or “complexed” with minerals to perform specific metabolic functions.
Seaweed Extract
Seaweed extract (usually derived from the brown alga Ascophyllum nodosum) is packed with natural plant growth regulators (PGRs) that tell the plant exactly what to do and when to do it.

Products
Saint Humic Acid’s product gallery is defined by the physical form of the humates, which dictates how they are applied (e.g., as a dry soil amendment, a liquid spray, or a feed additive)
How we work
Our Structured Process to Achieve Your Goals
01
Physical Action: The “Soil Architect”
Saint Humic Acid’s products (especially the granular forms) act as a glue for soil particles.
Thermal Regulation: The dark color of the humate helps the soil absorb more solar energy, warming the root zone faster in the spring.
Aggregation: It combines with clay particles to create “crumb structure.” This prevents soil from cracking and keeps it airy so roots can breathe.
Water Retention: In sandy soils, the high surface area of the humic molecules helps hold onto water molecules that would otherwise drain away.
02
Chemical Action: The “Nutrient Manager”
This is the most critical function. Humic acid has a very high Cation Exchange Capacity (CEC).
Fertilizer Efficiency: It stabilizes Nitrogen (preventing it from gassing off as ammonia) and prevents Phosphorus from bonding with Calcium or Aluminum, which usually makes it useless to plants.
Chelation: It “wraps” around metallic micronutrients (like Iron, Zinc, and Manganese) to keep them from getting locked up in the soil. This keeps them in a “liquid-ready” state for the plant.
pH Buffering: It helps neutralize both highly acidic and highly alkaline soils, creating a “sweet spot” (pH 6.0–7.0) where most nutrients are naturally available.
03
Biological Action: The “Microbe Fuel”
Saint Humic Acid doesn’t just feed the plant; it feeds the living soil.
Cell Permeability: On a cellular level, humic acid makes the plant’s cell membranes more permeable. Think of it as opening the “windows” of the cell so nutrients can flow in more easily
Microbial Stimulation: It provides a rich carbon source for beneficial bacteria and fungi (like Mycorrhizae). This causes a “population explosion” of microbes that further break down organic matter.
