Description

Humic Acid CAS NO 308067-45-0 is a complex mixture of naturally occurring organic acids derived from the decomposition of plant and animal matter, primarily found in leonardite, peat, and lignite. This versatile substance plays a crucial role in enhancing soil structure, promoting nutrient uptake, and stimulating plant growth, making it a cornerstone of modern sustainable agriculture. It is an essential input for manufacturers of high-efficiency fertilizers, soil conditioners, and animal feed supplements, serving the needs of the global agricultural, horticultural, and aquaculture industries.

Application

• Agricultural Fertilizers & Soil Conditioners: As a key active ingredient to improve soil cation exchange capacity (CEC), water retention, and microbial activity.
• Horticulture & Turf Management: For enhancing root development, seed germination, and stress tolerance in lawns, gardens, and greenhouse crops.
• Animal Nutrition & Feed Additives: Incorporated into livestock and poultry feed to improve gut health, nutrient absorption, and overall animal performance.
• Environmental Remediation: Used in bioremediation projects to chelate heavy metals and bind organic pollutants in contaminated soil and water.
• Industrial Processes: As a drilling mud additive in the oil & gas industry and a binder/dispersant in various manufacturing applications.
• Biostimulants & Organic Farming: A fundamental component in certified organic plant growth promoters and sustainable crop production systems.

Quality Control

Our Humic Acid is produced under a stringent quality management system. Each batch is tested to ensure consistent performance and meets specifications for key parameters such as humic acid content, fulvic acid content, solubility, and pH. Certificates of Analysis (COA) documenting these results are provided with every shipment to guarantee traceability and compliance with relevant agricultural input standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent caking and maintain product efficacy.
