Description

Product Description

Potassium Humate is a natural organic macromolecule extracted from high-quality weathered coal, lignite, and peat via advanced alkaline extraction and purification. It presents as black/brown amorphous powder, flakes, or granules, with good water solubility (≥95%) and chemical stability, suitable for pH 4.0-10.0 and resistant to 120℃ without decomposition. Non-toxic, residue-free, and highly compatible, it serves as an eco-friendly agent in agriculture, animal husbandry, aquaculture, and environmental protection.

Core Features

Natural & High-Purity

Strong Chelation

Easy Application

Purified to remove heavy metals and harmful microbes, with humic acid content up to 70%-95%.

Active groups (carboxyl, hydroxyl) boost nutrient absorption by 30%-50% via chelating trace elements (Fe, Zn, Mn).

Fast-dissolving, no caking, mixable with fertilizers, pesticides, or feed additives.

Application

Agriculture

Improves soil structure (loosens compacted soil, retains water/fertilizer), activates beneficial microbes, and enhances crop stress resistance (drought/cold/disease). Applied via soil (5-10kg/mu), foliar spray (0.1%-0.3% solution), or drip irrigation (0.05%-0.1% solution).

Animal Husbandry

Aquaculture

1. Application in tertilizer water: organic weak acids composed ot carbonhydrogen, oxygen, nitrogen and other elements, which can supplementthe carbon source of water.
2. Purify water quality: strong adsorption.

3. Physical shading: After dissolving, it turns soy sauce-colored, which canblock part of the sunlight from reaching the bottom layer, thereby preventing moss growth.

Environmental Protection

Shop Humic acid 99% Humic Acid CAS 1415-93-6 for Fertilizer-Detailed Image 5

Humic acid plays a vital role in shading-induced control of excessive plant growth. By modifying light penetration and absorption, it regulates key plant hormones like auxin and gibberellin, suppressing abnormal stem elongation. This promotes compact, robust growth with enhanced root development and improved stress resistance. Additionally, it optimizes nutrient uptake, ensuring balanced development rather than overgrowth, making it a valuable aid in shading-based growth management for various plants.

oil-based drilling mud additive"

Humic acid serves as a high-performance additive in oil sludge drilling fluids. It enhances fluid viscosity and shear resistance, stabilizing the drilling mud system under harsh downhole conditions. It also inhibits shale hydration and dispersion, preventing wellbore collapse, while reducing fluid loss to protect formations. Additionally, it improves lubricity, lowers drilling friction, and boosts the overall efficiency and safety of oil sludge drilling operations.
