Sodium Humate

Sodium Humate

Sodium humate is a sodium salt of humic acid, derived from natural humic substances found in soil, peat, and coal (especially leonardite). It is widely used in agriculture, animal feed, environmental remediation, and industrial applications due to its ability to improve soil structure, enhance nutrient uptake, and act as an organic stimulant.

Sodium Humate

Production Process of sodium humate:

Extraction: Humic substances are extracted from leonardite or peat using an alkaline solution (NaOH or KOH).
Precipitation & Purification: The extract is acidified to precipitate humic acid, which is then neutralized with sodium hydroxide to form sodium humate.
Drying & Crystallization: The solution is dried and processed into fine crystals or granules.


Applications:

  • Agriculture & Horticulture

  • Soil Conditioner: Improves soil structure, water retention, and microbial activity.

  • Chelating Agent: Enhances nutrient (N, P, K, micronutrients) availability.

  • Seed Treatment: Promotes germination and root development.

  • Organic Fertilizer: Used in organic farming as a natural growth stimulant.

  • Animal Feed Additive

  • Gut Health: Improves digestion and nutrient absorption in livestock.

  • Detoxification: Binds toxins and heavy metals in animal feed.

  • Immune Booster: Enhances immunity in poultry and aquaculture.

  • Environmental Remediation

  • Wastewater Treatment: Binds heavy metals and organic pollutants.

  • Soil Remediation: Helps in detoxifying contaminated soils.

  • Industrial Uses

  • Drilling Fluid Additive: Used in oil drilling for viscosity control.

  • Cosmetics & Pharmaceuticals: Sometimes included in detoxifying products.


Advantages of Sodium Humate Over Humic Acid:

Higher solubility in water compared to raw humic acid.
Easier to handle and apply in liquid fertilizers or foliar sprays.
More stable pH for agricultural use.
